Fuzzlord Riff Master

Classic Germanium Boost

Inspired by Iommi’s modified Dallas Arbiter Rangemaster effect unit used throughout the classic Black Sabbath recordings of the 1970’s, this pedal is designed to overdrive the front end of a slightly saturated tube amplifier into thick harmonic distortion while accentuating response and gain across a selected range of frequencies.
Each Fuzzlord Riff Master is loaded with a hand selected, exceptionally rare, NOS Phillips/Mullard “Red Dot” OC44 Germanium transistor as used in the original amp-top units from the 60’s. A four-position Depth control sets the pass-band of boost, which can be adjusted from the stock treble boost setting through to a smooth, harmonically rich, full range boost.
The circuit provides gain of up to 24db across the boosted frequency range, which proves highly responsive to both pick attack and guitar volume setting.
