The Crush Bass 100 is the largest amp in the Crush Bass range. It delivers 100 watts through a 15-inch speaker in a ported cabinet, and both the preamp and the power section are analogue. The tone section is an active three-band EQ whose middle band is parametric, with a frequency control for sweeping the mids.

A Gain control adds anything from light grit to heavy distortion. A separate Blend control mixes the driven signal with the clean one, so low-end definition is kept. Gain and Blend can be switched from a footswitch. A -6 dB pad switch is fitted for hotter inputs.

For connections there is a buffered effects loop for pedals, a balanced XLR output for the PA or a recording interface, and a headphone output with cabinet simulation for silent practice. An aux input takes a phone or player for playing along, and a built-in chromatic tuner is included. The cabinet comes covered in orange or black basketweave vinyl.
