Member Pekar poses the question – ‘Fancy a drink with that solo?’

This is a crackerbox type guitar amplifier I built into a vintage cocktail case. It runs on a 12 volt battery and uses a JRC386D to drive the 7″ driver.
The amps sound and output can be influenced by opening the case.

Hope that strapping keeps the bar kit from rattling too much. Dig that open/closed-back option – suave! – Link
