The Palmer PFFX allows you to individually switch on or off two effect loops, or connect both in series and thus supports customised set-ups, e.g. for rhythm and solo sounds. For the FX 2, a mute function for connecting a tuner can be selected and a ground lift switch helps to avoid ground loops. The PFFX can also be inserted in the effects loop of an amplifier. The flexible true bypass pedal is completely passive; for using the LED displays, a 9V block battery or an AC adapter with negative internal contact such as the Palmer PW9V are required.
