The Micro Terror is a miniature guitar amp head that combines one 12AX7/ECC83 valve in the preamp with a 20-watt solid-state output stage. The top panel has three controls, Gain, Tone and Volume, so it is quick to set up for clean or overdriven sounds.

It includes an auxiliary input for connecting a phone or music player to play along with backing tracks, and a headphone output for quiet practice. The chassis is white high tensile steel with a carry handle. At 0.85 kg and 16.5 × 13.5 × 9.5 cm, it is small enough for a desk or a gig bag.

The speaker output accepts 8-16 ohm cabinets, and the amp is designed to be paired with an external speaker cab, where an efficient cab gives the most volume. Optional FS-1 and FS-2 footswitches are listed as related accessories.
