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 Origin Effects DCX Bass is the bass-specific sibling of the DCX Boost, reimagining the Universal Audio 610 console preamp circuit for bass guitar rather than six-string. It shares the same Level, Drive, and Low/High Frequency EQ control layout with an EQ/Overdrive mode toggle and Voice tone-roll-off switch, but is voiced and gain-staged specifically to preserve low-end weight and definition rather than the guitar-focused EQ curve of the standard DCX Boost. It ranges from a transparent, tone-enhancing always-on boost to real console-style saturation and drive, aimed at bass players wanting studio-preamp character without losing low-end clarity.
