The “Red Knob Mod” version of Tonal Recall is built around 4 re-issued versions of the legendary MN3005 bucket-brigade delay chips. It’s maximum delay time is increased to 1100ms and the unmistakable analog character of this delay is front and center. Tonal Recall expands upon the classic vintage sounds associated with analog delays of yesteryear while bringing modern amenities such as tap tempo, optional bypass with trails, expression control over any parameter, and the ability to save presets. Every knob and switch is connected to a little digital brain while your guitar signal stays 100% analog and never gets digitally processed.
