From the vendor

Description

The Guitar Bass Driver contains (9) transistors to deliver a “larger than life” tube amp emulated tone found in old Ampeg SVT style amps. This circuit will certainly make your Bass come alive, it also sounds amazing for your 6-String Guitar as well. It will deliver natural sounding SVT style tones.

If you enjoy turning your gain to 10, finding a sweet spot position is easy using the volume and boost controls at 70-80% rotation, which will yield maximum drive with plenty of headroom.

Be sure to grab our genuine 2N5457 FET transistors for your circuit and a J113.
