Description
Unleash the power of the MXR M77 Custom Badass Modified OD, a one-of-a-kind overdrive effects pedal that delivers impressive performance and versatility. This pedal is a tribute to the classic overdrive circuit, but with modern modifications that enhance its functionality. It's the perfect tool for guitarists in pursuit of that elusive perfect tone.
The MXR M77 doesn't just add overdrive to your sound, it gives you the power to shape your tone in new and exciting ways. The 100HZ cut and boost control lets you focus your EQ for a tighter sound or boost it for a bolder, beefier tone.
But the real game-changer is the Bump switch. This engaging feature activates an alternate EQ voicing that boosts the lows and mids, creating a rich, full-bodied sound that will make your guitar sing. And when used in conjunction with the '78 Custom Badass Distortion, it can produce a variety of amp-like gain structures that won't mask your unique tone.
Key Features:
- Classic overdrive circuit with modern modifications
- 100HZ cut and boost control for versatile EQ shaping
- Bump switch for alternate EQ voicing that boosts lows and mids
- Works well with '78 Custom Badass Distortion for varied gain structures
- True bypass for preserving signal integrity when the pedal is off

Awesome
Awesome padal. Gives me the ability to sound like Angus Young. Simple controls, amazing sound. This pedal is always on my board. I use it as a clean boost and then mix it with other pedals.
Great Versatility
The level of control over your tone here is insane. I absolutely love it! Can you believe it only draws 7mA? of power? It's ridiculous.
