The MXR M77 Custom Badass OD is a thick and juicy overdrive with control over volume, gain and tone in addition to a fixed frequency 100hZ boost/cut knob that allows you to tighten up (cut) or beef up (boost) the tone to your desired sound. Finally there is a ‘bump’ switch that pushes the low mids for super beefed up tone.

Here’s what MXR say about the Custom Badass OD

Next up in the MXR Custom Badass line is the Modified Overdrive—a classic overdrive circuit with modern modifications for improved performance and versatility

For added flexibility, we’ve added a 100HZ cut and boost control that allows for a more focused EQ when cut, or a beefier tone when boosted. The Bump switch engages an alternate EQ voicing that boosts the lows and mids. Put it in front of the ’78 Custom Badass Distortion for a slew of amp-like gain structures that won’t mask your tone.

Distortion

Distortion pedals take your clean guitar signal and transform it into something bigger, bolder, and full of attitude. By clipping the waveform, they add sustain, bite, and aggression, creating that thick, compressed tone that’s powered rock music for decades. From the growling crunch of classic hard rock to the tight, saturated roar of modern metal, distortion is all about energy and presence. It gives every note weight and authority, pushing your amp to its limits and beyond.

There are countless flavours of distortion, each with its own texture and edge. Some sound smooth and creamy, others raw and gnarly like tearing fabric. It’s the sonic equivalent of turning up the heat until the sound cooks — rich, sizzling, and perfectly seasoned to taste. Whether used for rhythm muscle or soaring leads, a good distortion pedal doesn’t just add volume; it adds personality, grit, and that unmistakable sense of power under your fingers.

EQ

While Ed Sheeran primarily relies on the natural sound of his acoustic guitar and vocals, he occasionally uses EQ (Equalization) to shape and enhance his tone during live performances or in the studio. EQ pedals or onboard preamps can allow him to adjust the frequency response of his guitar signal to suit the acoustics of different venues or to achieve specific tonal characteristics. Here’s how EQ might be utilized in Ed Sheeran’s setup:

1. **Tonal Shaping**: EQ can be used to adjust the balance of frequencies in the guitar signal, allowing Ed Sheeran to shape his tone to his liking. For example, he might boost the midrange frequencies to bring out the warmth and presence of his acoustic guitar, or cut certain frequencies to reduce any harshness or mud in the sound.

2. **Feedback Control**: In a live setting, EQ can help control feedback by notching out problematic frequencies that might cause the guitar signal to feed back through the amplification system. This can be particularly useful when performing in venues with challenging acoustics or high volume levels.

3. **Room Correction**: In situations where the venue’s acoustics are less than ideal, EQ can be used to compensate for any deficiencies in the sound. By adjusting the EQ settings, Ed Sheeran can tailor the guitar tone to sound more balanced and natural, regardless of the room’s acoustic properties.

4. **Matching Gear**: EQ can also be used to match the tone of Ed Sheeran’s guitar to the sound of other instruments or equipment in his setup. For example, he might adjust the EQ to complement the tonal characteristics of his vocal microphone or to blend seamlessly with backing tracks or other instruments.

Overall, while EQ may not be a central component of Ed Sheeran’s guitar effects setup, it can still play a valuable role in shaping his tone and ensuring that he achieves the desired sound in different performance environments. Whether used subtly for tonal shaping or more aggressively for feedback control, EQ allows Ed Sheeran to tailor his guitar tone to suit his musical vision and performance needs.

Overdrive

Like a golden layer of melted cheese — warm, gooey, and just put it all over. It adds just the right amount of richness and grit, turning a clean signal into something smooth and savoury. Designed to mimic the natural breakup of a tube amp pushed to its sweet spot, overdrive delivers the flavour of classic rock and blues in every bite. From creamy mid-gain warmth to crisp edge-of-breakup sparkle, it’s the comfort food of guitar tone — simple, satisfying, and endlessly versatile. Whether it’s a mild crunch or a full-bodied roar, overdrive is where good taste begins.

Volume

Volume pedals control the output level of a guitar signal using a foot-operated treadle. They allow smooth volume swells, dynamic control during playing, and easy muting between songs. Volume pedals can be placed at different points in the signal chain to either control overall loudness or adjust gain and drive behaviour when positioned before distortion or overdrive pedals.
