MXR - Six Band EQ.

Upgraded with noise reduction circuitry, brighter LEDs for increased visability and a lightweight aluminium housing. It covers all the essential guitar frequencies, with each slider ready to deliver +/-18dB of cut or boost for incredible control over your sound. Create scooped mid rhythm tones with massive low end, add natural sounding warmth to a quacky acoustic pickup, eliminate onstage feed back and much more. You can also use it in the effects loop of your amp for a huge, sculptable lead boost. True hardwire bypass. Powered by 9 volt battery or AC adaptor
