Description

Unleash the ferocity of your guitar tone with the Maxon SM-9 Plus Super Metal distortion pedal. This powerhouse of a pedal is designed to cater to the most demanding metal enthusiasts, offering a wide range of high-gain sounds that can take your playing from the aggressive, scooped midrange of 80s thrash to the bone-crushing lows required for modern metal. With its intuitive control layout, you can sculpt your tone with precision and ease.

The SM-9 Plus features Gain, Level, Scoop, and Edge controls. The Gain control not only increases your distortion but also boosts the 1kHz midrange by up to 20dB, perfect for cutting through the mix. The Scoop control allows you to dial in the perfect mid-band frequency, ranging from 200Hz to 2kHz, while the Edge control lets you shape high frequencies from 2kHz to 15kHz.

One of the standout features of this pedal is its ability to switch between 9V and 18V operation. Thanks to an internal voltage-doubling circuit, the 18V setting offers improved frequency response and reduced compression, giving you a fuller and more dynamic sound. Housed in a durable die-cast zinc chassis with a rubber bottom pad to prevent slipping, this pedal is built to withstand the rigors of live performance and extensive touring.

Key Features:

  • Gain, Level, Scoop, and Edge controls for versatile tone shaping
  • Switchable 9V/18V operation with internal voltage-doubling circuit
  • Durable die-cast zinc chassis with rubber bottom pad
  • Mechanical true bypass switching for uncolored signal integrity
  • Easy-access battery compartment and LED status indicator
  • Powered by 9V battery or adapter (sold separately)
