Rehbein keeps a clean signal chain, plugging directly into a TC Electronic PolyTune 2, which feeds a Strymon Blue Sky that runs into a Radial SGI transmitter that feeds his Kemper. A Mission Engineering expression pedal allows Rehbein to tweak effects on the fly. Various wall-warts capable of handling 110-240v provide the power, except the SGI, which is powered by Native Instruments power supply. Klotz cables handle the wiring.
