Vibe and Rotary Speaker guitar effect. This is the second generation of the original model with an updated flex switch, which allows momentary or latching operation. The sound is adjusted using the Intensity, Level, Voice, Rate, and Throb potentiometers to achieve classic vintage tone, low frequency pulse highlighting, and thickens or thins the overall performance. In addition, it offers a 100% analog signal path and true bypass. The effect is equipped with a metal construction and is powered by a 9V or 18V adapter (not included).
