Abstract
A power module transmits power to and simultaneously receives a signal from a remote signal processing device, such as an effects pedal, which in turn transmits power to and simultaneously receives a signal from a musical instrument, such as a guitar. The signal that is transmitted from the musical instrument is received at the effects pedal or remote signal processing device and is subsequently transmitted from the device to the power module. The signal is received at the power module and is transmitted from the power module to an amplifier or other signal processing device.
