Great little micro sized overdrive distortion pedal. I love how it has level, tone, warm settings. Not all overdrives are created equal. I will look around for a power supply that works for this one but it's not guaranteed i will find one. It works perfectly however and the pedal has an upgraded button for your foot which is very nice as the original one being on a small pedal is easy to nick the volume knob etc. Mooer makes quality pedals, great for electric guitar, bass, etc. Free shipping. Great low price.
