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

The Roland Blues Cube BC-30 (30 W) and BC-60 (60 W) are the original solid-state Blues Cubes, sold as Tube Logic designs and designed and assembled in the USA. Each has a footswitchable Normal channel (Volume, Bright) and Lead channel (Pre and Post Volume), sharing EQ, presence and master on the BC-30. The BC-60 gives each channel its own EQ, adds Crunch on Normal and Boost on Lead, plus spring reverb, a Rectifex rectifier switch and an effects loop.

Tags: solid-state, clean, crunch, two-channel, mid-wattage.
