Following last year’s pedal debuts, Universal Audio’s UAFX range continues to grow with these new Amp Emulators, which the company says emulate the best vintage guitar amps of all time. 

Each pedal represents one particular amp type: Woodrow ’55 Instrument Amplifier is based on Fender tweed amps from the ’50s; Dream ’65 Reverb Amplifier represents the later black-panel Fenders with an emulation of the Deluxe Reverb; and Ruby ’63 Top Boost Amplifier channels our homegrown Vox AC30.
