Using the Electro - Harmonix Pitch Fork Plus is a breeze. First, connect your guitar to the pedal and then to your amplifier. You can adjust the pitch shifting and detuning using the controls for the two independent engines. The dedicated volume controls let you balance the Shift voices and the Dry signal. For routing, choose between the Main and Aux outputs according to your needs. To use presets, you can either select from the 10 factory presets or save and recall your own 100 programs. The Bypass footswitch is handy - in latch mode, it keeps the effect on or off, and in Momentary mode, the effect is active as long as you hold the switch. The User footswitch can be programmed for different functions like muting voices or jumping to presets. You can also use an EXP pedal or an external foot controller through the EXP and EXT inputs. When it comes to maintenance, keep the pedal clean and dry. Avoid exposing it to extreme temperatures or humidity. If you're not using it for a long time, store it in a safe place. And don't forget to use the included power adapter for powering the pedal.
