Additionally, the RE-20's "Expression" pedal offers further tonal control.
The RE-20 is a completely digital pedal, ensuring greater durability than analogue pedals like the Roland RE-201 while faithful reproduction allows for authentic analogue tape flutter and magnetic head sound saturation. Its tap input pedal allows users to adjust the RE-20's delay time, even offering delay time longer than the original RE-201's capabilities. Meanwhile, the RE-20's Expression pedal allows users to adjust parameters such as repeat, rate and intensity for a more personalized reverb.
