Audio Amp Co | Tweed Classics


Originally designed as a student and beginner amp we have to see it today as a professional rehearsal, studio/recording, backstage and living room amp.

This amp goes from clean to crunch without any pedal, for lead playing just add a good overdrive pedal or a booster. It is capable of producing sounds from blues to hard rock in an always ear friendly loudness. Amp sounds best with a 12″ speaker in the big cab, likes single coils and humbuckers.
