Maxon SM-9 Pro+ Super Metal Distortion - Used
Looking for crushing high-gain saturation with maximum clarity and versatility? This Maxon SM-9 Pro+ Super Metal delivers aggressive, tube-like metal distortion ranging from classic NWOBHM crunch to modern drop-tuned, scooped-mid brutality. Designed around an expanded, dual-ganged saturation circuit, the SM-9 Pro+ pairs interactive Scoop (mid-band filter) and Edge (high-frequency shelving) controls with an internal switchable 9V/18V operation for massive headroom and dynamic punch.
Condition is Very Good. The pedal is exceptionally clean overall, showing only a few minor cosmetic paint dings on the enclosure from light use. It is 100% fully functional, with smooth pots, crisp switching, and pristine signal throughput. Please see photos for exact cosmetic details.
Our technicians have thoroughly tested all jacks, pots, true-bypass switching, and internal voltage circuitry to ensure flawless operation.
