Verified · 88/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Spartan Bass 60 is a solid-state Epiphone bass combo from around 2001 with a 12-inch speaker. It has one channel with high and low inputs, a gain control, a sweepable Shape notch (85 Hz to 1 kHz), and low, mid and high EQ with 15 dB of cut or boost. An op-amp preamp with a built-in limiter feeds a discrete transistor power amp. Line out, preamp out and power amp in jacks let it patch into a PA or effects.
