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.

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 Master Effects Transmission is a bass preamp pedal, and this particular listing pairs it with a Yamaha BB1200, a well-regarded vintage Japanese-made bass known for its punchy, versatile tone, suggesting the listing bundles or references the preamp alongside that specific instrument rather than the BB1200 being part of the pedal's own name. As a bass preamp, its core function is shaping tone before the signal reaches an amp or interface, typically offering EQ shaping, drive or saturation, and a DI output for stage and studio use, positioning it as a tone-shaping utility rather than a distortion-focused effect pedal.
