Trace Elliot GP12 Series 6 preset

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

The GP12 Series 6 is Trace Elliot's all-solid-state preamp with the twelve-band graphic EQ, used in the AH200, AH300 and AH500 heads, the 1210 and 1215 combos and the GP12S rack unit. Unlike the GP12X, it has no valve stage or compressor, giving a clean, transistor-and-op-amp bass voice.
