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.

The Palmer PEABI is more than a simple switcher for two sources, it also provides level adjustment of microphone or line signals. Whether microphone or line signal, the PEABI toggles silently between the two inputs permitting fast and simple signal comparison and the connection of two sources to one input. Three slide switches select 15 dB of attenuation for input A and 6, 15 or 21 dB for input B. A ground lift switch eliminates earth loop hum. The PEABI is housed in a solid metal case with extended edges for optimum protection of the inputs and output. A red LED clearly indicates which input is active.

Pre-drilled holes permit simple and secure mounting in a rack or on a pedalboard.

The PEABI's circuitry is all-passive. A 9 V block battery is required to power the LED.
