Ampeg B-1 - Normal preset

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

The Ampeg B-1 and B-1R were solid-state bass heads from the mid-1990s to early 2000s, delivering 350 watts in a compact rack-mount format. The B-1R (rack version) was designed for professional bassists seeking a reliable, high-output solid-state head with the Ampeg tonal character. These heads were competitive with other professional solid-state bass heads of the era, offering clean headroom and the Ampeg EQ voicing that players expected from the brand.
