Gallien-Krueger 800RB - High preset

Verified · 82/100 confidence. Complete schematic. All component values readable. Parameters derived directly from the circuit.

The Gallien-Krueger 800RB is one of the most iconic bass amplifier heads ever produced, featuring a bi-amplification design that split the signal into high and low frequency power sections of 100W and 300W respectively. Its clean, punchy solid-state tone defined the sound of professional bass players through the 1980s and 1990s. Players like Flea and Sting relied on the 800RB for its tight, articulate response and reliability.
