The BASSRIG Fifteen is an all-analogue amp simulator and DI pedal that provides bassists with authentic Ampeg B15 Portaflex tones, all in a compact package. The original Ampeg B-15 is a small, low-powered 1×15 valve combo, known for its warm and punchy sound. It’s revered as the sound of ‘60s soul music and considered to be the holy grail of recorded bass tones. A real favourite in the studio.
This pedal is the latest incarnation of our Amp Recreation circuitry – also seen in the RevivalDRIVE, DELUXE55 and other BASSRIG models – which uses carefully designed analogue circuitry to recreate the entire circuit of a vintage valve amp. This includes a simulated preamp, phase inverter, push-pull output stage, reactive load, rectifier sag and an all-analogue cabinet simulator. All this adds up to capture not only the sounds but also the feel of the B-15 amplifier, in the context of a modern DI rig.
The BASSRIG Fifteen also features our AMP OUT EQ circuit. This tweaks the sound from the ¼” output, getting you the unique response of the B-15’s ported cab, even with the most modern full-range bass amps. With premium quality components and a brushed stainless-steel enclosure, the BASSRIG Fifteen is built to the high standard you expect from Origin Effects.
