Z.VEX Vexter Box Of Rock Distortion/Boost Pedal  From Zvex

This is definitely one killer little Box of Rock! Its distortion is as full and rich as the amp it was designed to emulate (see manufacturer description) and it takes absolutely no prisoners. You can easily set it to ring chords for days in true rock&roll style, or rip searing leads using it as your sole boost into the promise land. Its boost function is really useful as well. It can be run as a clean boost on its own, or in conjunction with the drive. I found it useful to set the drive volume to a dirty rhythm tone, and then use the boost to jump that sound up to a lead-level volume when the time comes. It responds well to rolling back a guitar's volume also. If you are looking for a versatile high-gain pedal, this one will be hard to beat!
