The brightest I played was my Carvin when I had the JB in the bridge slot. All maple neck-thru with an ebony fingerboard, carbon reinforcement rods in the neck, and a full floating Wilkinson VS-100 trem. I duly changed out the JB for a CC. Much better.
My new Carvin is pretty bright. I'm not sure of the material it's made out of though. I know the fingerboard is ebony, plus the pickups are pretty bright.
My vote goes to a a James Burton tele with the poplar body (he specified it for some of his early sig models). Poplar tends to have a tad more twang in the bass and top end and Teles will shatter glass if you tune the amp right, so that gets my vote.
those old retro things that came out of japa,n, all the wacko shapes and switches and knobs... weak pickups, all adds up to a really thin harsh tone. but well cool thru a fuzz pedal and a cranked amp. some great lo-fi tones.
