While the modern boutique amplifier market continues to swell and turn out numerous great options for musicians chasing unique tones, a small army of resourceful techs and electrical craftspeople are turning to the old tube circuit cookbooks and borrowing components and chassis from the past to turn old PA amps, phonographs, and Hi-Fi boxes into screamin' little guitar and bass amps for today's players. Old Bogen lunchboxes, Hammond organ electronics, RCA public address amps, Western Electric radio tuners, and countless other discarded oddities have found new life as tube-powered blues machines slightly modified for use with guitar, bass, keys, and any other electric instrument you've got kicking around. Have a look through this set of hand-wired hellions for an unlikely path to fat tones in unexpected packages, ready to play and turn any and all heads.
