Similarity
citedBlended 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.

Description

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 MXR M281 Thump is a bass preamp pedal offering active tone shaping, boost, and blend controls designed to give bassists precise tonal control and added punch. Built with MXR's rugged construction standards, it targets bassists wanting a dedicated preamp pedal to shape and enhance their tone beyond what their amp's built-in controls provide.
