This pedal is a clone of the rare and valuable MAESTRO BASS BRASSMASTER which was used in the 70s by Yes, Eric Johnson's bass player Kyle Brock, and many other groups. It is a fuzz with an upper octave sound like an octavia, specifically voiced for Bass but working well with guitar also. One of the problems bass players have always faced when using a fuzz pedal is
the loss of low-end. The Bass Octave Fuzz allows the player to blend the clean
signal into the mix along with the fuzz. The result is a monstrous roar of fuzz
with a thunderous low-end rumble. Not for the faint of heart!
