  1. No more stalling. The title says most of it, but a few pictures should fill in the blanks. White Limba, Padauk, Wenge, Hipshot stuff, single TV Jones Filter'Tron Classic Plus, 628mm ~ 648mm Multiscale (approximately Gibson to Fender)
  2. I am on the warpath of trying to figure out what scale I should use for the 1st and 6th strings on a multiscale electric guitar. I used to use .009s, but after trying .010s and liking the tone (and using them for a long time), I recently tried .011s and discovered (much to my surprise) that they weren't noticeably more difficult to bend. So now I am wondering what gauge strings I should use for the "best" tone (perhaps thicker is better to a point), but this post is not about that. If I settle on .011s, does that dictate an optimum scale for the 1st string to get very good tone? 24.5" to 25.5" seems like a bit too big of a range to arbitrarily choose just based on how close together I want the frets to be. Presumably there are tradeoffs and people differ in the qualities they prefer, so I am speaking in general terms. Then I wonder, having chosen X for the 1st string scale length, does that dictate an ideal scale length for the 6th string (which would be a .049 in my case)? (Math doesn't bother me.)
  3. View File Surunmaa 8-string compound scale guitar The Surunmaa design is an outline for a basic compound scale 8-string guitar over a 720mm (28,35") and 666mm (26,25") compound scaling. Initially designed for a single soapbar pickup (EMG 40-style, Seymour Duncan soapbars, etc.) with a minimal control pattern, the Surunmaa is a guitar focused on a tight toneful low end whilst maintaining a looser top end for more expressive solo work. The bridge configuration features the recently-released Hipshot Solo bridges allowing through-body stringing to be added. The modern headstock style derives from both an 80s Japanese influence with the a more modern Parker Fly-ish slant.

  4. We are currently about to start developing a range of kits for the DIY community, based around our Multiscale designs. These will be manufactured in Indonesia, rather than the usual Chinese kits, to allow for a high quality level. This will of course mean they are a little more $$$ too. We plan on 6 and 7 string versions, but there are some things we arent sure about. Most kits come as a premade body, and you basically finish it yourself with oil or lacquer, then assemble. Usually a headstock is either precut, or its the paddle arrangement so you can design your own. We'd like to consider either having a precut body, OR simply a body blank with all relevant routs completed (eg: pickups, controls, neck joint, plus bridge location). This will allow end users to cut their own body, but still avoid the more difficult parts like routing. So, you'd be free to design and cut your own body shape, plus your own headstock, but still have a completed neck shaft, frets, control and pickup routs, neck joint, etc. Of course, all kits will include hardware and pickups too, with upgrades available. Thoughts?
  5. Hello again everyone! It's been a year since I finished my explorer and I'm getting the itch again! This is one which has been in the pipeline for ages, but I wanted it to be right and it has slipped down the order a bit. As it happens, it works out quite well - This will be my seventh guitar build/renovation project, and to celebrate I'm biting the bullet and making it a seven string! At the moment, I'm sourcing parts/measurements/info/ideas but here are the current specs (subject to change through revealed ignorance!). * Through-neck (with contrasting lams) * "Black nickel" hardware all-round (if possible) with a medium-dark, figured top and contrast binding over a darker body * Probably two passive humbuckers (although not ruling out actives totally) * Ibanez RG/S/JS inspired body, but subtly more asymmetric - generally aiming for a clean super-strat look but not a flat-top * Asymmetric 4-3 headstock (matching body top) Right now, I can't decide between a multi-scale or a floating trem. I have long wanted to try out a multi-scale and with the benefits much greater for extended range instruments it seems a good time to do it! (I know that you can get hold of floating multi scale bridges, but to my eyes they are quite bulky (and horrifically expensive!).) It will be a while before I can start all this due to being on secondment with work in Spain, but I thought I would get a page up to collect some ideas. I have a couple of questions to start.. any help offered would be greatly appreciated! 1) Do I need to consider strengthening the neck beyond a normal DA truss-rod and the laminates for the sake of string 7 / long scale length? 2) I was thinking along the lines of a 26.5" - 25" fan with the perpendicular between 7 and 12. A 27" bottom would be nice, but I imagine that makes the fan quite tight(?). I'm not sure what the rules are here in terms of permissible scale differences. Any pointers regarding multiscales? 3) What are the best options for single-saddle bridge parts? So far I'm aware of ABM and Hipshot, but neither come in the black nickel finish I'm after (everything has chrome or black and I'm not bling enough for gold!) 4) Do people prefer a slanted nut, or a zero-fret and straight nut for multi scales? or is it another case of "bone vs plastic etc" where the jury is out?! Below are the current sketches for the floyd-based design - I found an "Imbuya" top online which looks a promising candidate! I have some cool ideas for fret markers, but I'm keeping them under wraps for now.. I'll upload plans/ target woods as they materialise to keep the ball rolling. Again, any help would be much appreciated! Cheers, D
  6. I've been itching to build a multiscale and I've never personally owned a 7 or 8 string. I decided to give them a go in one build. Some of the details are, as of yet, undecided. So far I have: 27.5"-25.5" multiscale 29 frets, Dunlop 6100 Seven Strings, I'll probably do the ABM single string bridges Instrumental Pickups, some sort of custom set Alder or African Mahogany Body Curly Maple and Black Walnut Neck Indian Rosewood or Birdseye Maple Board Painted in some sort of Dayglo color. I have the neon green, red, or yellow. First things first. I drew my full size plan. I also drew an additional 6 string plan that is not pictured. The "straight fret" is the 9th fret. The body is an offset dinky. My apprentice and I picked up some quartered hard maple, flat sawn curly maple, african mahogany, and alder. Ran it though the thickness planer, ripped it on the table saw and got ready for some glue ups. For the neck I ended up doing a seven piece laminate alternating curly maple and walnut. I rotated the maple to orient the grain to quarter sawn after I ripped it. Glue shot: While the neck blank was drying I hand planed three alder body blanks and glued those up as well. Purchased that No.5 Stanley on eBay for $25. As far as I can tell that plane was made around 1910? After all that jazz I ran the neck blank through the thickness planer. I have to make some big decisions. Birdseye or Rosewood board? Later this week I'll build the compound angle scarf jig, the table saw slotting jig for the fretboard, and maybe get to my body template squared away. I'm still on the fence about the body material and if I want to order a figured top and do a burst instead of a neon color. Thanks for looking.

    Is It Multiscale or Fanned Fret?

    Guitars and basses using compound scale lengths have exploded in popularity over the last two decades. Originally the province of boutique luthiers such as Ralph Novak, Ormsby Guitars, Conklin Guitars & Basses, blackmachine, Dingwall, .strandberg* (plus too many others to list) with several luthiers here on ProjectGuitar.com having designed and built their own, the last few years have seen compound scale length instruments become a mainstream feature. How and why would we incorporate more than one scale into an instrument? What advantages or differences do they actually offer? What are the most common misunderstandings or misconceptions? Why are terms being used incorrectly or interchangably? We'll cover a brief history of compound scale instruments, explore the theory and demonstrate how they're designed including their strengths/flaws.... ----==---- Obligatory boring history lesson The concept of a strung instrument utilising different lengths per string is not a new one, the most obvious and recognisable example being a grand piano or instruments such as harps, lyres, psalterys, hammered dulcimers, etc. Grand pianos commonly have over 200 strings with similar length/tension/pitch relationships This arrangement of using longer strings for the lower notes and shorter ones in the upper range is part of a greater relationship; the fundamental frequency of a vibrating string is a function of the free vibrating length, the tension within the string and physical mass by length ("gauge"). We don't need to go into the exact mathematics behind this relationship (more can be found through the virtues of Google, however this is very good, as is this) it can be summarised as: Higher pitches require.... short vibrating string length higher string tension lighter string gauge Lower pitches require.... long vibrating string length lower string tension heavier string gauge This is true for the most part. As this is simply a relationship, not all of these have to be true at the same time, however the other components of the relationship need to compensate. Okay, this has probably lost a few people already who just want to see the weird-looking instruments. At least we're not looking at the math! Simply, a lower pitch can still be produced by a lighter string gauge, however an even lower tension and/or longer string length will be required to make up. Harps, et alia. leveraged the parts of the relationship the best that they could given the limited string material engineering capabilities of the times; high tensions and gauges simply weren't possible. This placed greater emphasis on long string lengths for lower string tunings with the reverse for higher ones; a naturally-evolved solution for instruments covering a wide range of octaves. The Spanish guitar - the blueprint for what we might recognise as guitars - covered barely 3-1/2 octaves. String-making was such that it could meet the relatively modest demands of six strings over such a small range; string tension and mass by length were more than sufficient in the relationship to produce required tunings; a simple single scale across the entire instrument worked perfectly well. The model established by the Spanish guitar carried itself through to steel-strung acoustics, Hawaiian steel guitars, archtops, solidbody guitars, basses, etc. without the underlying single-scale architecture altering. Hold a Les Paul next to an original Torres (good luck with that) and the DNA is clearly apparent. Disadvantages of single scale instruments Standard guitars and basses sit on the cusp of practicality when it comes to the string pitch/mass/length/tension relationship. Many modern solidbody guitar/bass designs feature more than the "normal" number of strings and utilise tunings significantly beyond standard. Such "extended range" guitars and basses fly beyond the limits of our calm island of 6/4-string standard-E safety. This fundamental shift highlighted the inadequacies of a single-scale arrangement; adding strings to a standard scale produces flabby lower strings with insufficient string tension, requiring excessively-heavy gauges to compensate. Increasing scale length to compensate increases string tension over the higher strings requiring super-low gauges for playability! Accompanying alterations in the number of string courses and scale lengths is a shift in timbre around the instrument; baritone scale lengths with longer strings tensioned higher than usual emphasises the fundamental, lower and uppermost harmonic overtones becoming (appropriately) "piano-like" in timbre. Much of the softer tonality generally preferred in the upper ranges easily becomes strident, harsh and less "musical". It was only a matter of time before these limitations in single scale lengths had to evolve in the same direction as other wide octave range instruments. Enter the compound scale instrument At its simplest, a compound scale instrument features two or more scales. This can be as simple as having a hybrid extension beyond the nut (not entirely unrelated to a plectrum banjo).... Amfisound Hellbass .... or more commonly, non-parallel frets.... Ormsby Guitars GTR TX Production Model Advantages of compound scale instruments Having full access to the relationship between pitch/length/tension/gauge opens up design possibilities both as a luthier and as a musician. Single scale instruments only allow us to leverage gauge and tension within a limited range before playability, tonality and practicality become too significant to ignore. We don't want cheesecutter high strings simply because we extended scale length for the benefit of the lower notes. We don't want flubby nu-metal low notes simply to keep expressive bendier high ones. Compound scales allow us to pick and choose what works best for us. A 24" 1st string and 27" 6th string? Do-able. A 16" 1st string and 30" 22nd string? Strange, but theoretically workable. A welcome (but not strictly deliberate) side effect of introducing non-parallel frets in compound scales is a more ergonomic feel; as a 5-string bassist I can attest strongly that parallel frets require a degree of compromise and automatic playing adjustment....potentially with painful hand/wrist problems. That the architecture of your instrument starts affecting how easily you play the thing is a Big Thing. In the playing position, the wrist and elbow (even the shoulder) have mutually comfortable ranges of movement. Parallel frets on a single-scale instrument (especially those with longer, wider necks and many high frets or for players that barre like crazy) can often pretzel your arm out of an optimally relaxed playing position. Some say that Hendrix himself played behind his head thanks to the limitations of single scale guitars and that Eddie Van Halen jumped around simply to get himself into a playing positions. All we know is.... ....compound scales tend to angle the fretting hand more naturally from the lowest notes to the highest. Even designing in an additional 1" to the lowest scale of a standard 6-string guitar produces a more organic feel with non-parallel frets. In addition to this natural arc, instrument designers commonly specify a "perpendicular" fret or position; a single point on the fingerboard where the fret (or proportional relation between scales if not actually a fret) is perpendicular to the centreline between outer scales. This aspect of a compound scale is highly personal, being affected by playing style, personal physical differences and also those of the instrument. What is comfortable for one person may be different for another. This point is most commonly found anywhere from the 5th fret to the 9th, however in theory it can exist anywhere on the neck; even between frets or beyond the nut or saddles! The advantages of compound scales to instruments are distinct; they unlock design aspects which are otherwise constrained through habit and tradition, plus they allowing instruments to be voiced more fairly from the lowest to the highest registers. The Novax® Fanned-Fret® System In spite of a fretted compound scale instruments existing hundreds of years ago, Ralph Novak patented the idea (more accurately, the process) for a compound scale guitar in 1989: the Fanned-Fret® system. The patent itself has expired, however Ralph continues to enforce intellectual property rights over the system and its trademark, licencing its use to luthiers selling their instruments within the US. Unlike a single-scale instrument where frets are parallel to each other, the Fanned-Fret® system arranges frets according to a geometric pattern whereby the straight line paths of each fret (plus the nut and theoretical bridge witness line) converge on a single point in 2D space, not entirely dissimilar to representing depth within single-point perspective. As a simple method of producing compound scales across several strings, it is elegant and very easy to implement: Generalised layout of a Fanned-Fret® system It does however possess one crucial flaw; the system only truly works if all of the strings are parallel to the reference scale. As with most things, taking an idea to a logical extreme serves to highlight fundamental issues. Consider a convergence point way off to one side with respect to the centre of the reference scale: (zoom to embiggenate) Theoretical extreme of a Fanned-Fret® system on a seven-string instrument As can be seen from the (nth root of 2) reference scales transposed onto outer string paths, a Fanned-Fret® system fret placement would leave bass strings progressively flatter further up the fingerboard and treble strings progressively sharper; so much so, that the 24th fret is approximately one semitone sharp! Plotting true nth root of 2 fret locations along each string path demonstrates that the usefulness of fret placement from a single convergent point in space is poor at best unless one wants to work with no string taper. Whilst discrepancies in a real-world Fanned-Fret® system implementation will be in the order of a few cents, the theoretical basis of the system is not truly a sound one; those cent errors add up. A reliable system for producing compound scales should be fit for purpose as opposed to being merely simplistic, clever-sounding, approximate and trademarked. Extending out true nth root of 2 fret placements disproves the convergent point idea Regardless of these yawning chasms, the Fanned-Fret® system introduced compound scale instruments into the consciousness of guitarists and luthiers, and is an important milestone to recognise in compound scale instrument design. Languagewise, it is important not to confuse the term "fanned frets" with anything but the Novax® Fanned-Fret® System. Not all non-parallel/compound scale instruments are "fanned frets". The Fanned-Fret® System is a distinctive and specific enough method that the term is not a catch-all for non-parallel fret design. Whenever you hear the term "fanned fret" used, ask if it's actually Fanned-Fret® or not. Interpolated Dual Scale Fret Placement Okay, I just made that name up. It does however describe a better way of producing a working multiscale fret placement for any range of equally-spaced strings. Referring back to the previous diagram showing why a single point in space does not work demonstrates that by subdividing the two outer string paths and "joining the dots", each intermediate string's placement is perfectly in line. Theoretical 22-string instrument. joining the dots from an nth root of 2 scale placed over the outer strings This system is more or less the basis behind how FretFind2D works when plotting multiple scales, and produces fine instruments that intonate well. If like myself, you prefer to design your instruments by hand in CAD then it is sufficient to test your multiscale layout by stretching a scale template over each string path as in the diagram above. If the points between string paths and the interpolated frets coincide, the design is proven to be good. In Closing.... Compound scales in guitars and basses have represented a significant evolution in our instruments, and one that would be ridiculous to ignore. Amongst the many fundamental compromises and imperfections baked into our perceptions as what constitutes a guitar, continuing to maintain a single scale length is one we can happily grow out of, and continue evolving. -------- All trademarks, service marks, trade names, product names and logos appearing in this article are the property of their respective owners and used under the doctrine of Fair Use for educational purposes.
  9. Well i think it's time to announce my next build. This guitar will be a Multiscale (25,5 - 26,5) hollowbody. With flamed maple on top, middle piece will be red alder, and the bottom is flamed maple. Im planning on doing a carve on both top and bottom. Neck will be flamed maple with black and white ebony fretboard. bindnings will be claro walnut,black abs and with abalone purfling. the hardware will be gold. The finish of this guitar will be transparent white. I will take a lot of influenses from this guitar. http://iheartguitarblog.com/wp-content/uploads/2012/03/0616EXXX54BPFMT3OX_01.jpg Here is a picture of the fretboard blank and neck blank.
  10. Greetings! I'm new to the forums and have enjoyed looking at all the awesome projects other builders have shared! I'd love to get your opinions of the two new models I just completed.
