The Mad Professor Supreme Overdrive is an exceptional dual-channel drive pedal designed in collaboration with tone master Matt Schofield, delivering two unique but complementary overdrive voices. Wrapped in a gorgeous sparkly blue enclosure, the Supreme lives up to its name—offering smooth, expressive low and medium-gain tones and punchy, dynamic drive with remarkable versatility. Whether you’re chasing creamy lead tones, gritty rhythms, or a thick stacked gain tone, this pedal adapts seamlessly to your needs, especially in a live setting.
CONSTRUCTION AND DESIGN
Aesthetically, the Supreme is a stunner. Its sparkly blue finish is both classy and eye-catching on any pedalboard. Built solidly and clearly designed with working musicians in mind, the pedal feels reliable underfoot and ready for years of heavy use. The single-switch operation and stacking toggle make navigating complex tone scenarios easy—whether you’re switching between A/B or layering both for more intensity. It’s a road-worthy boutique unit with stage-friendly brains and brawn.
LAYOUT
Each side of the pedal—A and B—features identical control layouts: Volume, Drive, Treble, and Bass, giving you the flexibility to fine-tune each voice independently. The stacking toggle switch is key: it allows you to choose between either/or operation or stacked mode, where both channels run in series. This adds a third tonal voice, making the Supreme functionally a three-channel overdrive, all accessible with a single stomp.
SOUND QUALITY
Here’s where the Supreme lives up to its name:
-
A Side (inspired by the Royal Blue Overdrive): Rich, smooth, and warm. Perfect for liquidy lead lines and thick, harmonically rich rhythm work, especially when paired with a neck pickup. The gain is present but always musical, never harsh. I found this side very useful for thickening up my Stratocaster.
-
B Side (a brand-new design): Punchier and more focused, this side leans toward crunchy, articulate rhythm tones and cutting bridge pickup leads. It brings in a touch of amp-like sag and headroom, perfect for dynamic players. This side was excellent for generating cutting lead tones on my P-90 and Humbucker guitars.
Stacked together, these voices create a lush, compressed drive with remarkable sustain and harmonic depth—ideal for soloing or driving an amp hard. Importantly, the EQ sections on both sides are powerful and musical, allowing for everything from scooped mids to mid-forward bite without losing clarity or feel.
APPLICATIONS AND AUDIO EXAMPLES
The Made Professor Supreme Overdrive shines across genres. It’s especially at home in for classic rock, blues, and moderately-gained rock music. This isn’t a fuzz or high-gain monster—it’s a refined drive pedal, perfect for players who live in the gain sweet spot. I really enjoy stacking the two sides, using just a touch of gain on each side. As I mentioned before, the ability to stack makes this actually feel like a 3-sided pedal. The supreme also stacks well with other pedals, I paired it with a more aggressive pedal, the Janis.lv Miesnieks and was able to coax some marshall-like crunchy tones from the two.
The pedal brings out the most in your instrument, and works well with single coil, humbucking, and P-90 pickups. Each side of the pedal has strengths, and depending on which of those pickup types you’re using, can be tailored to achieve a wide variety of tones. Have a listen to some files recorded using the Supreme, with both my Stratocaster and Les Paul guitars, tracked through a Fender Princeton using a Shure SM57.
