Setup
Power Requirements
The Fundamental Series Tremolo pedal requires a minimum of 100mA of power. Use a standard 9-volt DC power supply with a center-negative plug.
Connections
Connect your instrument or previous effects pedal to the 1/4 inch (6.35mm) audio input jack. Connect the 1/4 inch (6.35mm) audio output jack to your amplifier or next effects pedal in the signal chain. Ensure all connections are secure before powering on the device.
Operating Instructions
Controls
- Rate: This slider controls the speed of the tremolo effect. Move the slider up for faster modulation and down for slower modulation.
- Depth: This slider adjusts the intensity or depth of the tremolo effect. Higher settings result in a more pronounced volume fluctuation.
- Volume: This slider sets the overall output volume of the pedal. Use it to balance the effect's volume with your dry signal or to provide a slight boost.
