Ampeg VT22 / VT40 - Channel 2 preset

Verified · 90/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The VT22 and VT40 are Ampeg's tube guitar combo amplifiers of the early 1970s, sharing their chassis with the V-4 bass amp. Channel 2 on the VT22 delivers a harmonically rich driven tone. The VT series' four 6L6 output tubes and tube-driven reverb give it a bold, American character well-suited to blues and classic rock.
