This pedal works great!

The RP80 combines the tones of 11 vintage and modern Amps with a palette of programmable studio quality effects (up to 9 at once) with a built in expression pedal for unparalleled real-time control of your sound. Using a multi-effects device has never been easier thanks to the RP80?s no-nonsense user interface. Just select the effect and dial in one of the great pre-programmed settings. If this was not enough, the built-in Drum Machine is a great tool for practicing with; and an easy-to-use 13-LED array tuner ensures you're always in tune. The RP80 comes ready to use with 40 great Factory Presets, and includes 40 User Presets for custom creations. The rear panel features a single 1/4" input, 1/4" left and right outputs, and a 1/8" stereo headphone output for late night rehearsal.
