I've been planning/building an Eub/DB for jazz for a long time now, and I've finally finished it. I love DB - how they sound, the scale length, watching a jazz bassist thumping away with a small ensemble, actually playing them.. the whole thing. But I'm not a fan of the size, or of the traditional DB look - much too 'antique-ish' imo (also, when I was much younger I was locked inside a DB case at an orchestra rehearsal as a gag, I think it scarred me ). The body is poplar with a layer of Quilted/flamed?¿ maple on top. The neck (bolt-on) was shaped from a 5 piece maple laminate 'club', and is reinfornced with 1/2" square hollow steel (it's actually not that heavy) under the fingerboard. I didn't want it to be adjustble or flex under tension, I wanted it super straight. The fingerboard is also flamed¿?/quilted maple. It's 4 strings, and each string has it's own seperate piezo element. There's also a piezo element mounted in the headstock which gives that really good thump sound. The bridge is wenge and is height adjustable (each half). I also built a preamp that I was originally planning to install into the bass, but I ended up installing it into some other DIY rack gear. <img src=http://patrick.sunscapeweb.com/eub/Front.jpg border=0> <img src=http://patrick.sunscapeweb.com/eub/HeadstockFingerboardFlame.jpg border=0> <img src=http://patrick.sunscapeweb.com/eub/NoStand.jpg border=0> <img src=http://patrick.sunscapeweb.com/eub/Profile.jpg border=0> I'll have some sound clips soon. I really dig the noise this thing makes; it's sort of a cross between a really long scale fretless BG (sustains forever) and an amplified DB (thump + overall 'sound').
