Overdrive
Mad Professor 1
The “Brown Sound” blew minds around the world during the late ‘70s and early ‘80s. Mad Professor took that sound, distilled it into stompbox form, and turned it into the 1. The 1 runs from medium- to high-gain for sheer rock and roll aggression while a built-in ‘70s-style reverb effect lets you add just the right amount of ambience and depth. You can get an instant dose of legendary rock guitar sound with a single stomp.

Overdrive
Mad Professor Big Tweedy Drive
The Big Tweedy overdrive guitar effects pedal from Mad Professor takes its tonal cues from the super rare High Powered Tweed Twin amp. You get the same fat, punchy mid-range and bite you’d expect from a vintage ‘50s American tweed amp. The Big Tweedy’s tone is very touch-sensitive, too; once you dial in your preferred gain level using the Drive knob, you can still use different picking attacks and your guitar’s volume level to fine-tune it even further.

Mad Professor Blueberry Bass Overdrive
Give your bass sound an overdriven kick. Yeah, the Blueberry Bass Overdrive effects pedal from Mad Professor is “just” an overdrive pedal, but it packs a lot of tonal possibilities into that narrow definition. The Nature knob does heavy duty work in that department. It lets you darken or brighten up your bass tone, which also affects the amount of overdrive that gets added to which frequencies. Set it to low and low frequencies get more overdrive; high frequencies become more overdrive at high Nature settings.

Distortion
Mad Professor Evolution Orange Underdrive
Almost every pedalboard out there has an overdrive pedal or two in it. But underdrive? That’s a completely different monster.

Your favorite amp’s sweet overdrive tone won’t get dark and muddy when you turn down your guitar’s volume. The Evolution Orange Underdrive lets you keep that great tone and response, but minus the dirt.
