Tremolo guitar effect with JFET-driven Level control provides plenty of clean input gain. This is the fourth generation of the original model with an updated flexi-switch allows momentary or latching operation. The effect offers three Slow, Mid-Tempo and Fast sound modes that can be controlled with the 3-way switch. In addition, the sound can be set using the Depth, Level and Rate potentiometers. The effect is true bypass and is equipped with a metal construction, an expression pedal input, a single footswitch, an LED, and is powered by a 9 V adapter (not included).
