A slight departure from many of AcmeBarGig's previous amplifier models, Preampus Brain was designed to produce a vintage British tone. Rather than cloning one specific amplifier model, AcmeBarGig decided to take their favorite features from several different amps and combine them into one model. Preampus Brain yields tones ranging from classic '60s crunch to the roar of a modded '70s stack.
