A slightly used Strymon Riverside that was traded in to us. Strymon's Riverside multi-stage drive effects pedal goes from crystal-clear clean boost to thick, modern high gain without sacrificing sound quality throughout the range, and that's just the beginning. Utilizing analog and digital circuitry, the Riverside's variable circuit tuning ensures you're tone will always be in the sweet spot, no matter how much gain you pile on. An intuitive yet comprehensive set of controls allows the Riverside to work with any amplifier and guitar combination. And Strymon loaded the Riverside with plenty of secondary functions that are sure to make it the centerpiece of your rig. oks and plays fine. Comes with power supply.
