Origin Effects BassRig Fifteen
Origin Effects · pedal
The Origin Effects BassRig Fifteen is an all-analogue bass preamp pedal meticulously recreating the sound and feel of the vintage Ampeg B-15 flip-top, widely regarded as the holy grail of recorded bass tone. Rather than emulating the amp digitally, it reconstructs the original tube signal path in analogue circuitry, including a simulated push-pull output stage and a reactive load, so the preamp compresses, sags and blooms under playing dynamics the way the valve amp does. The voice is warm, round and thick with a rich, slightly compressed midrange and a soft, musical top end -- the sound of Motown, funk and classic rock records. An all-analogue cabinet simulator feeds a DI output that is stage- and studio-ready straight into a desk or interface. Built to studio-gear standards in a heavy stainless-steel enclosure. Reviewers report it is at its best with passive basses such as a Precision, and less flattering with active instruments.
