U-Sound Stamp'O Comp



The "Stamp'O Comp" compressor is the outcome of several years of research and experiments. The core of the unit is a CA3080A chip - a 1970's circuit in a metal case while many contemporary compressors use the CA3080E chip that goes in a plastic case. Naturally the difference between the two is not the case material but the technology matter. Nevertheless both amateur and professional guitar players who use "Stamp'O Comp" say it conveys the guitar tone without losing its authenticity. The pedal can also be used as a booster (if the level of compression in minimal). Other than "Sustain" and "Volume" controls the pedal has the "Tone" knob and the "Stamp" switch that lets it possible to make the guitar sound distinct in the overall mix.
