This is the same preamp as used in the Human Bass Roxy model except that this version also has a blend for two pickups.
This has a push/pull volume knob where is pulled up, the preamp is disengaged but you still retain a passive tone control with the Treble knob. This is a great, practical design. I had this in an American Deluxe Pbass and it worked fantastic. I am selling the bass, so I put it back to stock.
I would take a trade for a Demeter Compulator pedal, but would like to get cash for this.
