Query: MXR 10band eq

This is yet another stunning piece of MXR equipment suitable for live performance. Ten designated bands of EQ adjustment with easy to use LED-lit sliders. Volume and gain faders, foot operated on-off push button control, all in MXR's typically rugged housing. Clean, effective EQing. Great for bringing out just the right frequencies on guitar, bass, keys, etc. Requires 18v negative center power. At $100 a perfectly functional to-the-point piece.
