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.35% — 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 Boss ODB-3 Bass Overdrive is a dedicated bass guitar overdrive designed to add harmonic grit and distortion without losing the fundamental low-end definition essential for bass in a band mix. A balance control mixes the overdriven signal with the clean bass signal, preserving the fundamental while adding harmonic content. The two-band EQ shapes the overdriven signal independently. Delivers subtle warmth and grit at low gain through bone-crushing distortion at high settings. A long-standing standard in bass overdrive, used in rock, metal, and alternative bass contexts.
