BAR/OLC Tube Cricket

The Tube Cricket is a half-watt guitar amp collaboration between Beavis Audio Research and OLCircuits. This bizarre recombination of ideas (think Jeff Goldblum in “The Fly”) yields a nice gainy sound that won’t disturb sleeping kids, neighbors, or your parole officer. This kit runs on the included 12 VDC wall-wart adapter and can power a 4x12 cab for meaty tone.

Note1: this is the pre-built version for illustrative purposes. The kit version will be bare metal... an open canvas upon which to add your touch.
Note2: the aesthetic 'rollbars' (near the tube), are no longer available.
