Brand new old stock (N.O.S.) Fulltone Bass-Drive Mosfet pedal.

This is the description from the Fulltone website before production stopped:

Bassists need dirt too! But no one, until now, has given you something that works, with all the full, rich bottom-end that you deserve, damn-it! BTW, many guitarists use and prefer the Bassdrive for Guitar!

The Bass-Drive is a lot like its cousin the Full-Drive2, but voiced with an extra octave of bass coverage.... still giving a natural, uncolored FATNESS to your thang.

From just adding a little grind, to replicating a raging SVT, to sounding like Jack Bruce in The Cream (he's got one already!)...

THIS WILL DO IT!

Bass-Drive devotees include:
Jack Bruce, Steve Stevens, and many more!
