JIM DUNLOP MXR WHE-206 WAY HUGE RED LLAMA 25TH ANNIVERSARY OVERDRIVE GUITAR EFFECT PEDAL

The Red Llama™ Overdrive is powered by a single 9-volt battery, a 9-volt AC adapter such as the Dunlop ECB003, or the DC Brick™ and Iso-Brick™ power supplies. The power input is a 5.5mm x 2.1mm jack with the positive voltage on the outer sleeve. Using an external power supply will disconnect the battery. Disconnect the input jack to preserve battery life when not in use. The pedal will lock into bypass mode when it is time to change the battery. It also includes power protection circuitry to prevent damage from AC power supplies.
