So yes, many years of playing i have finally discovered how awesome my FENDER Jazz V sounds in Eb!! My new project is in this tuning and i have no idea why i never went there before. The vocalist can hit everything without straining, and my bass just seems to absolutely LOVE it! Playing just seems "easier", if that makes sense... I have done Drop-D, and some other odd tuning things, but i have never just flattened the whole thing a half-step. I get it now. Anyone else have this revelation? EDIT: Clearing up the fact that i'm not playing jazz. I play original rock/reggae. Jazz V is my Fender Am Std Jazz 5.
