MXR TOM MORELLO POWER 50 OVERDRIVEFor more than 30 years, the key component of Tom Morellos raw, hard-hitting sonic voice has been his amp setup. The MXR Power 50 Overdrive captures the sound and functionality of that setup for use with any rig, whether you have a simple combo amp or a high-end custom stack.This pedal is powered by one 9-volt battery (accessible via battery door on bottom plate), a 9-volt AC adapter such as the Dunlop ECB003/ECB003EU, or an MXR BrickSeries power supply.The Power 50 Overdrive is fitted with the same control interface as Toms amp, featuring Gain, Bass, Middle, Treble, Volume, and Presence knobs so that you can replicate his exact settings or tune the sound to your own taste.
