Powered by DigiTech's AudioDNA2 DSP processor, the RP90 guitar pedal includes detailed models of boutique stompboxes, amps, cabinets and effects. The RP90's tone and effect libraries allow you to quickly and easily get any sound you want. It's like having a music store at your disposal. From hot-rodded rock and roll to metal, the RP90 has everything you need to get the tones you want or need. To top it all off, the chorus and DigiTech Whammy effects can be re-arranged to go before the amp model or after v which ever you desire. The RP90 features a 1/4" guitar input along with separate left and right 1/4" output jacks that can be connected to either an amplifier or mixer for direct recording with a press of the Amp/Mixer switch that engages the internal speaker cabinets for direct recording. Rounding off the outputs is a separate, stereo 1/8" headphone jack for practicing purposes. To control the wah and Whammy, the RP90 has a built in treadle. Because music isn't just about getting tones but writing songs, the RP90 effect pedal also features 40, high-quality drum patterns to aid music creation and practice. Feeling sterile and need inspiration? Just turn on one of the drum patterns and see where it takes you.
