Manufacturers info:
BJF design versatile fuzz pedal
Hand-made in Finland premium quality fuzz pedal. Mad Professor Fire Red Fuzz (FRF) is a fuzz pedal that is easy to play with long sustain and lot of tone variations. The pedal has a compressed, deep effect to allow equal sustain throughout the fretboard. Tone control was specifically designed to allow tones from mellow fuzz, through slight midcut to thin bright fuzz
The FRF is not another variation of a classic fuzz design but an unique pedal with its own character and extremely versatile Tone control. It is great for recording different layers of Fuzz tones from haunting dark to cutting thin bright. What ever setting you use the tone is always very musical and controllable.
Like all Mad Professor pedals FRF is hand made in Finland using only premium components, to give years of trouble free operation with superb musical tone.
Controls
VOLUME: Sets the level of distorted signal
FUZZ: Controls fuzz depth from just slight to heavy fuzz
TONE: controls EQ of fuzzed sounds: mellow to CCW rotation, slight midcut in mid position and thin fuzz to fully CW rotation.
