Holy hell, Mattia. That's the best guitar I've ever seen. Swear, no exaggeration-- you may have made it out of scraps, but it encapsulates almost everything I love in a guitar design.
Related note:
I've always wanted a Steinberger "broom"-style guitar, partially because one of the only guitarists I'd consider a "guitar hero" of mine (Martin Tielli of the Rheostatics) did some seriously amazing work on one, and I always thought they looked cool, too (hey, I have weird taste). I've been considering a build on and off for a long time now, but the tricky part is the hardware. Those ABM bridges are expensive, and I want a trem. Can't get the 'basic' Steinberger trem anymore, and when you CAN, they don't include the piece that goes at the "head" of the neck for some reason. I almost bought a Spirit by Steinberger cheapie just to steal the hardware from it, but I suspected that it wouldn't live up to my expectations.
The next closest thing I've seen is the Speedloader, but it hasn't caught on yet (and may never) and therefore the strings are prohibitive and difficult to find in Ottawa.
In any event, that story doesn't go anywhere except to mention that I want to build a headless, that it might end up being a "broom" style, but that after seeing Mattia's masterpiece there (scrapperpiece, my ass!) I may very well change my mind about the broom (but not about the headless).
