Using the Fender Compugilist Compressor/Distortion Guitar Effects Pedal is a breeze. First, connect it to your guitar and amplifier. You can use the compression or distortion effects separately by switching them on and off independently. Just turn the knobs to adjust the settings according to your preference. For example, use the bass boost feature to add more low - end to your sound. When you're on a dark stage, turn on the LED - backlit knobs to see your settings clearly. As for maintenance, keep the pedal away from moisture and extreme temperatures. Clean it with a soft, dry cloth regularly. Also, make sure to use the correct power supply to avoid any damage to the pedal.
