Mad Professor’s new “1” pedal is a combined distortion/reverb pedal designed to provide the sought-after “brown sound” of late ’70s/early ’80s guitar. With an intense drive that retains high definition and a built-in reverb that adds ambience and depth, this pedal is truly the one.

Mad Professor was founded in 2002, the brainchild of designers Harri Koski, Jukka Monkkonen and Bjorn Juhl. Combined, they share 45 years of experience developing and building pedals and guitar amplifiers, and have turned Mad Professor into one of the fastest-growing companies in the business.

Mad Professor (press release)

Mad Professor "1"

”1” is a distortion/reverb pedal designed to provide the sought after “Brown” guitar sound of the late 70’s early 80’s, when played through a clean amplifier.

Like that legendary tone, this pedal produces intense drive while retaining high definition. The pedal also includes a built in reverb circuit to add ambience and depth to your sound.

“1”’s gain ranges from medium to very heavy distortion. The amount can be easily controlled via the volume control of your guitar. (Input impedance is set to facilitate this, and is somewhat negated if a buffer or buffered effect is used ahead of “1”.)

The Brown knob controls the amount and harmonic overtones of the distortion. Getting the exact tonal quality is the key to this legendary sound and “1”’s Brown and Presence controls help it appropriately interface with a wide variety of pickups and amplifiers.

“1”’s built in Reverb circuit with a Level control for setting the ambience. The sound is modeled after the studio reverb found on classic recordings from the 80’s. The decay time is preset so as not to mess the rhythm of your playing. The preset decay time and tone can be modified with trimmers inside the pedal.
