The Crush Acoustic 30 is a lightweight combo that delivers 30 W RMS through a custom 8-inch full-range speaker. It has two independent channels: a high-impedance instrument input with a three-band EQ, and a low-impedance XLR microphone input with its own preamp, gain and EQ. The mic channel offers switchable +48 V phantom power and a mic/line selector.

A shared effects section provides chorus and reverb, with effect select, blend and level controls. A variable notch filter on the master section lets the player reduce feedback and room resonances. Other features include a pad switch and colour switch on the instrument channel, a buffered effects loop and an aux input for backing tracks.

For connections, the amp has an XLR output and a line output for feeding a PA or recording setup. It can run from a DC adapter or from ten AA batteries, which give up to about ten hours of use. It comes in orange or black, and FS-1 and FS-2 footswitches are listed as optional extras.
