Carvin R600 / R1000 preset

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

The R600 and R1000 share a hybrid Carvin bass platform: a 12AX7 tube stage in the preamp alongside JFET and op-amp stages, three-band EQ with low boost and mid shift, a nine-band graphic EQ, compressor/gate and bi-amp crossover. Bipolar output stages deliver 600 or 1000 watts, with the R1000 adding extra output pairs.
