TC Electronic RC 4 switch pedal

Step On It!

This is the accesory you can't afford to miss if you own an RH450, RH750, Staccato'51 or Blacksmith amp - plain and simple.
In essence, you get a super handy tuner indicator right at your feet, a mute switch and three preset footswitches for instant access to the presets you've created on the amp.
Oh, and it draws it's power directly from the amp so no power supplies or batteries. Should we just wait here while you go buy one?
