Are they available in 10" radius or just 9.5 and 12?
We can do 10.
Wow, never seen that before. It looks WAAAAY cool! You've actually used one, Proteus?
I"ve been a fan of everything Gamechanger does - always a seemingly daft and laughingly camp-concept idea, then brilliant engineering and exquisite implementation. I pre-ordered the day it was announced, and yep, I have one.
In its just-emulate-a-Bigsby mode, it's dead-on in behavior and very hard to distinguish from the real thing; if you're listening for it, in a solo guitar setting, you can
sometimes hear the transition from standard pitch to the pedal's pitch-bent sample. But only sometimes, and after the brief (ms-length) transition, the tone is all your own. The only difference is that your guitar always stays in tune. And in a band context, you'd never hear that slight slur of transition.
Then there's all the other stuff it does: pitch bends up to an octave, up or down, a cyclical vibrato courtesy of a built-in LFO, and the ability to blend the pitch-bent signal with clean signal for subtle dissonances (or, with the vibrato going, a chorus variable by pedal).
You go through a period of adjustment where you cautiously check your guitar's tuning after any move you know would throw it out with a regular Bigsby - then you remember the pedal never touches the string and start whammificabigsbating with abandon. And you never have to think "wish that guitar had a Bigsby" again. Bigsby your 12-string Ric, Bigsby your bass, Bigsby your eeeelectric mandolin, Bigsby everything.
