- Slow/Fast (toggle/footswitch)
Tremolo uses solid-state transistor for preamp and vibrato, instead of fragile inefficient lamp based units. If the depth is turned down this pedal doubles as an outstanding booster. In effect you get two pedals in one box. Also you can plug into a power amp and jam because this thing is a preamp. Great effect based on beautiful sounding vintage design, with modern, quality modifications. True Bypass switching. Switch version, when you flip switch down speed increases at max setting. Normal version has a slower minimum setting.
