Peavey TNT 150 preset

Close · 70/100 confidence. Most values readable. Minor gaps filled by inference from similar circuits.

The Peavey TNT 150 is a late-1980s solid-state bass combo. High and low gain inputs feed an op-amp preamp with pre gain and a bright switch, then a nine-band op-amp graphic equaliser for detailed tone shaping and a post gain. A built-in bucket-brigade chorus with its own controls is footswitchable, and an effects loop, preamp out, power amp in and line out sit ahead of a transistor power module with Peavey's DDT protection.
