The Guitar/Bass Driver is based on original "Tonmann Layout" revised for fabrication by Bruce R. This circuit contains (9) transistors to deliver a "larger than life" tube-like tone found in old Ampeg™ style amps.


While this circuit will certainly make your Bass come alive, it also sounds amazing for your 6-String Guitar. It will deliver a natural sounding tube style breakup as you turn the gain up full.


In my opinion this is a must have board for your collection.
