Vintage B-15 Tone, Studio Ready

The BASSRIG Fifteen brings the legendary sound of the Ampeg B-15 Portaflex straight to your pedalboard.

Fully analogue and built around Origin Effects’ Amp Recreation Circuitry, it recreates the entire signal path of a vintage tube amp, from preamp to power section, phase inverter to reactive load, and finishing with an authentic 1x15 cab simulation.

The result is the unmistakable warmth, punch, and musicality of the B-15, ready for the studio, the stage, or your home setup, without the weight or maintenance of a vintage amp.

Classic B-15 Feel

Plug in and you immediately get the thick, round lows and smooth, musical breakup that made the B-15 the backbone of countless soul, Motown, and 60s recordings.

The push-pull power amp simulation and reactive load give you the dynamic feel and response of the original design with impressive realism.

Ready for Any Rig

The dedicated AMP OUT EQ makes it easy to integrate the BASSRIG Fifteen with any amp or stage monitor, while the DI output delivers a polished, mix ready signal directly to the board.

The BLEND control allows you to mix in clean tone for extra clarity and punch.
