The headstock design is still preliminary, I just stuck it on there quickly in photoshop, without giving it anything like the careful attention I gave the curves of the body.

I'll be trying some alternative designs for it soon- I dont think the current one compliments the body curves very well. I might even go with a 3X3 or 4X2, since the 6 in a line headstock does look kinda large.

Thanks for the comment though... I might go back into cad/ photoshop and make a perfect rendering of what I want to achieve. This one has a few flaws cos its basically a load of previous renderings I made for other ideas chopped up and reassembled :D

Or perhaps a more elongated top horn an inch or two and increasing lower fret access? I guess the access depends on whether you'll actually use those frets! An inch back on the neck and an inch on the top horn would make a huge difference. As you say Ben, it's a mockup at this stage :-D

With a 27"-28" scale and a neck-body join at #18-20, methinks you might be really reaching for #1. You might consider moving the entire scale back toward the a** end by a few frets. It will also help with balance.

maybe... but I'm fairly big (6 foot 2"), and when I hold my guitar and imagine an extra 2 or 3" on the end of it, it doesnt seem like I'd have any problem with reach.

I'll be drawing it out full size/ getting someone to print my cad drawing soon, so I'll get a better feel for the dimensions then. Thats probably going to be the easiest way to imagine it when finished.

Thanks for the comments!

In that case you could probably scale the width of the body say 10-15% wider and not ruin the aesthetics - that would help you resolve any neck joining point/access issues....

I'm six foot, but i'm not a skinny guy so I tend to make five-string basses almost look small! It's made me consider the issues of bridge placement and balance on the eight-string 30"!

I'm finalising my wiring diagram now...

Quick poll of opinion;

What sounds would you choose to fill the last 2 spaces on my 6 way rotary switch?

I have decided upon:

1. Bridge humbucker (series)

2. Bridge humbucker (series) + Neck P90 in series with bridge

3. Bridge humbucker (parallel) + Neck P90 in parallel with bridge

4. Neck P-90 on its own.

5. ????

6. ????

The options that I am considering for 5 and 6 are:

A. Bridge single coil (split humbucker) in series with the neck p90

B. Bridge single coil (split humbucker) in parallel with the neck p90

C. Bridge single coil (split humbucker) on its own

D. Bridge single coil (split humbucker) in series and out of phase with the neck p90

E. Bridge humbucker (series) in parallel with the neck p90

F. Bridge humbucker (parallel)

What do you think would provide the best sound/ most tonal variation?

No problem then! That's the beauty of building your own.

As for the pickup options, I can imagine that you might be able to wire the pickup outputs up to a mini set of terminals inside the control cavity that allow you to make connections through the use of tiny jumpers that are just a U-shaped piece of metal covered in plastic, which slides over (and connects) pairs of pins. I've seen such things several times in the electronics we use in our lab at work.

Send the outputs to your rotary switch. This way you could try all sorts of different combinations without having to resolder.

Today I bought a load of MDF and drew everything out full size in preparation for making templates. I wish I had my camera- it's looking really promising as a design.

I settled for a 27.5" scale length in the end

Done B)

When I first printed out my cad drawing, seeing it full size made me realise that the body was too small. I made it about 1.5 inches wider and now it looks fine. Wont help me with my aim to minimise the weight (since zebrano is very dense), but it definitely needed enlarging.

very cool design I like alot.

Cheers!

A and C would be the most versatile.

Cool, thanks for the opinion. I may just take your word for it and go with that in fact.

I really have no idea what the others will sound like. I'd guess that B and 3 would sound similar, and I think that D may not be possible with a 4 pole switch, given some of the other configurations I've chosen, but otherwise I've no way of deciding.

That is a good idea... could end up pretty complicated though, I have enough trouble getting my head around it on paper. I'd have to make sure I laid it all out logically. I thought about prototyping it with a breadboard somehow, but your idea is a lot better.

The configurations are all easy to understand; the challenge is figuring out how to achieve them all when limited to only 4 poles.

i think the design looks great. I think the large headstock suits it well.

Cool; because the 6 in a line is staying :D

When I drew it out full size I tried a few different headstock shapes and tuner arrangements- the one that looked best was the 6-in-a-line, but on the final design the headstock has ended up a little smaller and a slightly different shape to in that image.

Plus the 6 in a line was the only one that would allow me to use an idea I had, that should let me use higher gauge strings without making the strings any harder to bend (I'll explain it fully when I get to that stage in the building process :D )

I just wish my wood would arrive now

Damn postal strike :D

Still no sign of the wood... its been a while now. I'm going to phone craft supplies on monday if its not here by then.

I did however finish my templates for the body and neck (I placed it next to my sisters guitar to give a better indication of its size).

I settled for a 27.5" scale in the end.

Just one more template to make for the neck pocket, trem and pickup routes.

In the new knob layout, the smaller knob nearest the neck is volume, the other small knob is tone and the 3rd larger knob is the pickup selector.

a few more pics:

Thanks for the positive comments!

Prostheta- I hadnt really thought about it yet... I'll probably wait until its finished and then see what looks and feels most natural.

I got bored today and decided to make something...

PHTO0002-1.jpg

Its a poor-man's drill press :D - a stand that holds my electric drill. It doesnt bear the wait of the drill or anything, its basically just a bit that holds the drill, and a set of guide rails that keep it it perpendicular to the surface being drilled.

I tried it on scrap and it actually works pretty damn well. It only works on flat surfaces, but that's all I'll need it for. I made it pretty sturdy and it seems to work accurately without the bit wobbling around.

I just ordered my pickups and trem,

I decided on:

GFS Crunchy Paf for the bridge, GFS 'Mean 90' for the neck and this trem

Edit: And now I just ordered everything else I need from stewmac :D

That makes the overall cost for the guitar, including the new tools I bought, just under £150. Not bad!

My Wood AND My stewmac order both arrived today :D

My stewmac stuff made it to my doorstep in like 30 hours... wow.

I spent the afternoon thinning my body blank, and then I made a start on rough cutting the outline.

Things I learnt:

1. Zebrano is damn hard to plane.

2. A better plane would be a wise investment.

3. removing less than half an inch of zebrano can make a surprising amount of mess!

4. Zebrano is damn hard to cut (my jigsaw seems to work its way through it at about 1mm a minute :D )

I'll have to take some pics of the wood tomorrow- it looks really nice

Also I tried the tap test thing on the wood out of curiosity- the zebrano just made a standard noise really... but the wenge however was a different story- my neck blank rang like a bell! I was really surprised by the sound it made, sounded more like I was knocking on metal tubing or something.
