This is what i hope to be the first of many.
See the whole build over at http://decibelguitars.com/proto1.
2010.07.14 Update: Complete! At least until i decide to start modifying it and swapping out components to test other ideas.
Rear view. The aluminum control cavity cover is a quickie that i fabricated just to keep the innards from spilling out. It does a decent job, though! I’ll probably get better plates fabricated, likely from aluminum.
View from the butt end of the guitar. Custom humbuckers from Nordstrand Pickups with 1/4″ pole pieces. Badass.
Here you can see the radius on the top of the body. It’s approximately 16″, so everything follows the arc of the fretboard radius. It’s slightly flattened in the middle to allow easier mounting of the bridge.
Recessed controls. I like that they’re sunk out of the way. Future builds may be a little less recessed, as it does pose some issues, mainly because there’s some wobble to most pots, which causes the knurled knobs to make contact with the walls of the recess when attempting “pinky” swells.
A close-up of the player’s view of the controls. The toggle is out of the way enough for me, but some players may not like it. I may consider moving the controls further back.
One niggly little imperfection i’m disappointed with… the depth stop on the drill press i was using either wasn’t set right or it slipped, and one of the “pin” holes for the Sperzels got drilled right through the face. I did a quick fill, but didn’t try very hard to make it disappear. It’s there as a reminder to ALWAYS TRIPLE-CHECK THE DEPTH STOP! And hey… it’s a prototype!
The amazing disappearing upper horn! It’s incredibly comfortable, and surprisingly strong! In the future, i will likely do the top radius first, and then the carving inside the horns to leave a bit more material there for strength.
The neck heel is deeply contoured and tapers away from the full body thickness to about 1/2″ where it meets the neck.
A lot of material has been removed from the lower cutaway area to give very smooth and comfortable access to the upper register.
Here you can see the organic blending of planes, lines and curves… visually interesting and extremely comfortable.

My compliments on a beautiful result! I have some Q’s about coloration in the second last picture. Would you please PM me?
