Using this Fender Trapper Dual Fuzz Guitar Effects Pedal is easy. First, connect your guitar to the input of the pedal and then connect the output of the pedal to your amplifier. You can start by adjusting the global Tone and Contour controls to get the basic sound you want. If you like synth - like tones, switch on the high octave for the first voice. For a grittier sound with less noise, use the interactive noise gate on the second voice. When you're on a dark stage, the LED - backlit knobs will help you see your settings clearly. As for maintenance, keep the pedal in a dry and clean place. Avoid exposing it to extreme temperatures or moisture. If there's dust on it, you can gently wipe it with a soft cloth. That's all you need to know to make the most of your Fender Trapper Dual Fuzz pedal.
