- INPUT (1/4" Jack): Connect your guitar or the output of a preceding effect pedal here.
- OUTPUT (1/4" Jack): Connect this to your amplifier's input or the input of the next effect pedal in your chain.
- 9VDC (Power Input): Connect a standard 9V DC power adapter (center-negative) here.
4. Setup Guide
Follow these steps to connect your SLO Pedal:
- Ensure your amplifier is turned off or set to a clean channel.
- Connect your guitar to the INPUT jack of the SLO Pedal using a standard 1/4-inch instrument cable.
- Connect the OUTPUT jack of the SLO Pedal to your amplifier's input using another 1/4-inch instrument cable.
- Connect a 9V DC (center-negative) power adapter to the 9VDC power input. The pedal requires 7mA of current.
- Once all connections are secure, you may power on your amplifier.
Important: Always use a regulated 9V DC center-negative power supply. Using an incorrect power supply can damage the pedal and void the warranty.
5. Operation
The SLO Pedal is designed to be intuitive. Experiment with the controls to find your desired tone.
- Engaging the Effect: Press the footswitch to toggle the effect on (LED illuminates) or off (LED off).
- Gain Staging: Start with the GAIN knob at a lower setting and gradually increase it to achieve more saturation. The SLO Pedal excels at high-gain tones, but can also provide subtle overdrive.
- EQ Adjustment: Use the TREBLE, MIDDLE, and BASS knobs to sculpt your tone. The MIDDLE control is particularly interactive and can significantly alter the pedal's character.
- Presence Control: The PRESENCE knob adds brightness and cut, helping the pedal sit well in a mix.
- Deep Switch: Engage the DEEP switch for a fuller, more resonant low-end response, ideal for mimicking the feel of a large speaker cabinet.
