Strymon Riverside - Multistage Drive - Multistage overdrive effect pedal

"Riverside’s cascading gain stages create harmonically rich tones that are immensely musical and natural—from silky clean overdrive to colossal distortion, and all points between. The analog JFET front-end ensures that Riverside responds to your guitar with uncompromised dynamics and feel. The precision crafted DSP generates dynamic complexity and pleasing harmonics at every stage, letting your amp shine at any gain level. Riverside takes your amp to places you never knew it could go.
Riverside’s continuously variable circuit tuning dynamically tweaks multiple parameters under the hood so that the sweet spot follows you at any gain setting. As you turn the Drive knob, Riverside makes continuous adjustments, tuning the circuit for optimum tone. This results in an incredibly versatile drive pedal that is equally capable of providing sparking cleans, mild overdrives, high-gain leads, and heavy saturated distortions."
