The Shin's Music BMP1 Bass Master Preamp is a hand-built Tokyo bass preamp recreating the preamp circuit of a vintage Fender Bassman tube amp using discrete circuitry in a compact enclosure. The voice is thick and rich at the bottom with a fast, articulate response, adding weight and warmth while preserving the character of the instrument plugged into it. Gain is deliberately set low, so it will not produce heavy distortion on its own; instead it gives the natural, soft clipping of a tube amp pushed at high volume. Alongside the familiar Bass, Middle and Treble EQ, a DRV mode adds the nuance of a tube amp's drive channel, and Custom versions add switchable input impedance and a three-stage drive EQ. Built by engineer Shinichi Suzuki, whose work is widely trusted among Japanese professional bassists.
The Tech 21 SansAmp YYZ Shape-Shifter is a signature bass preamp and DI from Tech 21 (New York, USA), co-developed with Geddy Lee of Rush as a companion to the GED-2112, adding a harmonically rich drive mode inspired by the tones of the Rush classic YYZ for aggressive harmonic bass distortion alongside the SansAmp clean preamp channel.
