The Character control alters tone to provide several choices of sounds from the early '60s to classic "super valve" to thick and funky to overdriven saturated distortion. There is a three-band active EQ, a full-range Drive control and the Bite switch adds a presence boost for better note definition. Lastly, the Blend control allows mixing the direct signal with the SansAmp Tube Amplifier Emulation circuitry.

Other features include a switchable SansAmp XLR DI out, effects loop, headphone out, Speakon® speaker connectors, and a worldwide switchable power supply.

The Tech 21 VT Bass 500 Bass Amp Head sells for $695 MSRP and the matching 1x12 bass cabinet (pictured) with custom-design 12-inch speaker, woven grill and coordinating piping is also $695.
