Super cool modded Boss TR-2 Termolo. Has two individual speed knobs and an extra foot switch to switch between them on the fly. Also has a master volume, so no more drop in volume when you engage it. When you turn on the pedal it goes to the first speed you set, then click the extra foot switch and that goes to the second speed, still one click only for pedal on and off. $85 shipped, USA and Pyapal sales only.
