The BASSRIG Fifteen is an all-analogue amp simulator and DI pedal that authentically captures the unmistakable tones of the Ampeg B-15 Portaflex — the holy grail of recorded bass tone and the beating heart of 1960s soul music.

Using our acclaimed Amp Recreation Circuitry (as seen in RevivalDRIVE, DELUXE55, and previous BASSRIG models), this pedal reproduces the entire circuit of a vintage valve amp — including preamp, phase inverter, push-pull output stage, reactive load, rectifier sag, and all-analogue 1x15 cabinet simulation. The result is a studio-ready, fully analogue B-15 experience in a pedalboard-friendly format.

To complement the launch, our Cali76 Bass Compressor will also be available in a matching “Fifteen Blue” finish — an ideal pairing for bassists chasing true vintage character.
