  1. I'm most likely going to do both: shield the cavity/unit and use the cap. We'll see what occurs.
  2. Hey all; it's been a while since I've stopped by this forum. I've been really busy with my repairs business and haven't had much time for recreational luthierie in a while. But I'm back!!! Here's my dilemma. I recently purchased an Artec VR2 on-board guitar preamp (it's a variable boost that's not over-the-top). Well, before I install it into a custom build that I'm about to begin, I built a small project box to test it out... When I engage the boost (no guitar hooked up to the cable leading in) and turn the boost up, I begin to hear it pickup AM radio transmissions (think Spinal Tap folks, it's the same issue)... I need to make this stop before I begin the routing job for its installation. If I can't make it act only as a boost and not pickup the radio frequencies, then I can't use it for this project. Now I currently suspect the cause for this is a lack of shielding from outside frequencies. It's mounted in an old Seymour Duncan pickup box for testing purposes only. So, could a good copper-foil shield keep out the frequencies? Virok
  3. So now that I see where I went wrong (actually, as I drove home from the shop tonight I had the epiphany)... 24 - 16.865 = 7.135 So, the distance from the bridge to the neck pocket is 7.135 inches. Well, since I need as close to 7.135 inches to finish the scale length from the heel of what ever neck I use, I calculated this using a 25.5 scale 22-fret neck... 25.5 - 18.344 = 7.156 I think I can do it using this and just adjust the saddles on the bridge to make up for the difference. I am going to give it a shot...
  4. Ok... I kindof did the math this way and I think it should work out ok... Scale length divided by the difference of the 21st fret from the nut and the total scale length would equal the approximate ratio of where on the scale the neck must be placed... So, I ran a few tests... 25.5 (scale length) - 17.919 (distance of 21st to nut) = 7.581/25.5 = 3.363 24 (scale length) - 16.865 (distance of 21st fret to nut) = 7.135/24 = 3.363 24.75 - 17.392 = 7.358/24.75 = 3.363 28 - 19.676 = 8.324/28 = 3.363 Doesn't this mean that if the heal of the neck of a 21 fret guitar (regardless of the scale length) will most likely bolt into the same place?
  5. I have a customer who has a 24" scale guitar with a 21 fret neck installed, but he wants it to have a 25.5" scale 21 fret neck installed instead. Before I order the neck and end up with a headache in the shop trying to make this work, is this a possibility?
  6. Hey all; I've been MIA for quite some time. Things at the repair shop over the past year have been craZy (any VERY busy too). But alas I am back during the holidays to pick your brains a bit! A buddy of mine bought an old Mosrite 335-ish guitar. The frets are really worn down and since he is a semi-professional touring musician, we concluded that a refret would be in order. Now I've done quite a few refrets in my time as a luthier, but not yet one on a "zero-fret" guitar. In general, I'm thinking that using a slightly larger fret wire for this fret may be in order, but when I think about a normally constructed guitar, as long as the guitar is set-up properly, wouldn't the same height/size fret used on a zero fret work just as well with less need to address lowering the nut (in this case zero-fret) action? Anyone with experience in a zero-fret job, let me know your approach. Greatly appreciated as always fellas.
  7. That's a great start... only the switch I am attempting to use is the one in the diagram below... .... so how do we make your suggested wiring scheme work on this style switch?
  8. A friend of mine showed me the pick-sized strobe tuner back in October of last year. It was interesting. I didn't really like it much, and since I tune my own guitars to Eb, I wouldn't be able to use it at all. The only tuners I use are Petersons (I use a Strobo-Flip at my workbench & a Strobo-Stomp on my remote station). They are quite small and very accurate. This pick-sized thing isn't exactly something to holler about.
  9. Y'know, it may be able to re-tune itself, but what about the truss rod? A guitar is set up properly with the correct tension on the truss rod to counter the tension of a particular gauge of strings in an equally particular tuning. Take a guitar set up for 10's in standard tuning and then detune the guitar for, let's say, dropped Db, then you have a boat load of buzzin' all over the neck. I'm not too happy with the robot guitar concept... but alas, that is only my opinion.
  10. Instead of using sandpaper, I like to use a flat-head screwdriver to gently scrape any film from the surface of the pot back. Also, instead of taping (since over time electrical tape will leave a gooey residue on the covered areas) try using heat-shrink tubing. You can pick it up at your local hardware store (or Home Depot, Lowes, etc.). It's fairly cheap.
  11. Here is a guitar that a fellow student built in luthierie school this past summer. It is completely bloodwood, and yes it was heavier than heck!
  12. Hello again everyone! I know it's been quite some time since I posted anything on this forum, but I've been extremely busy with my repair shop & I haven't had the time to do much else of anything. A friend of mine recently decided to modify his Epiphone Les Paul (I haven't seen it personally, so I cannot elaborate much on the model), and he wants to install a 5-way rotary switch to select between three pickups. He was going to bring his guitar and the 5-way/4-pole rotary switch to another friend of his to do the work for him since I had no clue as to how this could be done. Unfortunately, I think he ran into some issues getting this done through his friend and I am now going to tackel this project personally. So, my question is: how can I wire a 5-way, 4-pole rotary switch to select between 3 humbuckers ala Strat-style?
  13. Yeah, I already looked into that. I'm not trying to replace all of the tuners for this guy. Instead, I just want to replace the one tuner that is broken & retain as much of the original spec's & appearance as possible.
  14. I have tried eBay, and I can't find it anywhere else. I need ONE Gibson Firebird-style tuner for a Gibson I am repairing for a friend. I know that Gibson used a modified banjo-tuner for these things, but I can't find a replacement tuner anywhere!!! Can anyone help?
