The Inanimate Carbon Rod (ICR) Tap Tempo was inspried by rods used to control the fission rate of nuclear reactors.  The soft (no click) footswitch is rated for 50,000 stomps!


This tap tempo is availible in either Normally Open (NO) or Normally Close (NC) switch configuration.


Normally Open tap tempos work with many JHS, Line 6, Electro Harmonix, MXR, Behringer, Eventide, or any other pedal that requires an NO tap tempo.


Normally Closed switches work with many Boss pedals or any other pedal that requires a NC tap tempo.  Check the host pedal manufactures specs to determine which type you need. Either polarity will work with most pedals, the difference being the correct polarity sets the tempo on the downward tap, the wrong polarity sets it on the release of the footswitch. It's not the end of the world if you pick the wrong one, since you'll find it's still easily sets the tempo. If you're not sure, contact our customer support at


Please note that this version functions exactly the same as the discontinued ICR deluxe except that it DOES NOT glow in the dark and DOES NOT glow under black light, but it still looks awesome
