Garnet Lil Rock B90L / L90L preset

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

The Lil Rock was offered in bass (B90L) and lead (L90L) versions sharing one circuit, with a value table setting the tone-stack differences. Two inputs feed a 12AX7 stage, treble and bass controls and a second 12AX7 stage, with the volume on a rear-panel control. A 6SN7 long-tail phase splitter drives a push-pull pair of fixed-bias 6V6GTs on a silicon bridge rectifier, with speaker feedback.
