The Guyatone AC-105 is a compact power supply designed to deliver stable DC voltage to effects pedals, replacing the need for multiple batteries. Its housing is built for pedalboard mounting, with a low-profile footprint that fits beneath most pedal setups. The unit accepts standard AC mains input and outputs a regulated DC signal through a single cable, which then connects to a pedal's power jack. This model provides a consistent voltage level suitable for typical 9-volt effects, reducing the risk of tone degradation or unexpected shutdowns that can occur as batteries drain. The AC-105 includes a status indicator to confirm that power is being supplied, and its cable is detachable for easy routing and replacement. No audio signal passes through the unit, so it does not alter the sound of connected pedals; its sole function is to supply clean, continuous power for reliable operation.
