In this review post we’re going to be discussing the MXR Custom Badass™ ’78 Distortion, including an overview of its unique features.

Product Description

The MXR Custom Badass ’78 Distortion is a factory-modded pedal that roars with huge amp stack tones and old school tube amp-like distortion.

We took a classic distortion circuit and hot-rodded it to the next level for over-the-top soaring leads and rich, saturated rhythms. With only three knobs, dialing in Badass tone is a cinch. The CRUNCH button allows you to choose between two different modes of diode and LED clipping, boosting the harmonic content of the distortion.

The ’78 Distortion’s wide open amp-like sound sounds great whether it’s in front of a clean amp, a slightly dirty amp, or a full-on overdriven amp. Under the hood, this high-performance machine features top-notch circuitry and hardware meant for a lifetime of use.

Our Verdict

If you like raw, ripping ’70s distortion, you’ll go crazy for the Custom Badass Distortion ’78. MXR did an excellent job at capturing a period of guitar tone that many of us adore and encapsulating it in a pedal. It’s sensitive and can produce notes that are molten and never-ending in your hands. It has a distinct personality, but it is also sensitive to the subtleties of your instrument and pickups. The ’78 is vintage and absolutely badass, much like an American muscle vehicle from the decade that bears its name.

Where to Buy

The best place to buy this product has to be Amazon, due to their competitive pricing and fantastic customer service.
