Tuning B to D??~??

yah, you would need to tighten the truss rod, but even then, there is so much tension that something may warp.....never heard of anything happeneing to anyone before, but ya never know. Also wouldn't it hurt the strings more? those were meant to be tuned standard....so I'd think all the strings would break, thereby releasing all the tension, and the neck bowing back in insane amounts...

I dunno.
 
B to drop D? It'll be higher tension. E down two steps to C is just slightly higher tension than a B string tuned to pitch. I found this out tuning a BEAD bass to CFBbEb. So D would be even higher tension than that, so yeah, a truss rod adjust is more than likely going to be nessicary.

I'd only do it if you knew you were going to keep the bass like that for a long time.
 
maby i should just lower my E LOL. but hey...lets say i had 2 basses. keep one regular BEADG. but with the other one, what if i took off the B, replaced teh B string with another E-string, and then lower that one to D. or maby just give it up and just live with it. But would the 2 e-string thing work??~??
