Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.43% — somewhat different

The Ampeg Classic Analog Bass Preamp is an all-analog bass effects pedal replicating the preamp circuit of the iconic Ampeg SVT amplifier in compact pedal format. A three-band EQ provides Bass at +7/-20 dB at 40 Hz, Mid at +5/-11 dB at 500 Hz, and Treble at +10/-10 dB at 4 kHz, with a preamp gain stage capable of +18 dB boost. Ultra-Hi and Ultra-Lo passive tone switches shape the frequency response for classic SVT character. True bypass, 9V DC at 20mA, internal -15 dB pad for active basses. Matte black die-cast zinc chassis measuring 2.2 by 2.4 by 4.5 inches, weighing 0.6 lb.
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.
