For the discerning Fuzz Face and Rangemaster player looking for a wide variety of sweet sounds at your feet. For the fuzz, toggle between a pair of germanium GT404B transistors, a pair of NTE123 silicon transistors, or a mix of both. The GT404B are the NPN version of the “BART” transistors. The NTE123 are the silicon used in the Texas Square Face. The Rangemaster Boost uses a 2N1308 germanium transistor.
 
Why 3 Footswitches? Left is ‘Fuzz’, right is ‘Boost’ (Rangemaster treble booster). The black A/B footswitch in the middle brings versatility to a new level. It toggles between 2 sets of “Input” and “Bias” knobs, so you can create 2 sounds which are wildly different, and toggle between them.
 
The Input knobs (think guitar volume knob cleanup) mimic the effect of turning down your guitars volume knob - ie. the Fuzz Face cleans up when turned down).
 
The Bias knobs change the character and texture of the fuzz (not the minor, barely discernible bias adjustments found on some pedals). With so many possibilities: glassy cleans, gritty overdrives, huge fuzz sounds, glitchy gated sounds…and on and on…you’ll be glad you don’t only have to choose one.
One way to look at it is this: you’ll have a 5 stage drive/fuzz at your feet (Rangemaster [RM];  Yellow Fuzz; Red Fuzz;  Yellow Fuzz + RM and Red Fuzz + RM).
 
Bass/EQ controls: The bass knob is an input capacitor blend, a versatile EQ control. The "Range" switch for the Rangemaster (RNG) toggles between 3 modes, original (trebly), mid range and full range/bassy. You can also have different EQ settings for each (A/B) mode, with the switch on the back - it makes the B (yellow) mode use a fixed input capacitor independent of the bass knob.
The Pickup Simulator (switch on back panel) allows you to place this pedal anywhere in your signal chain without affecting the sound. 
Pedal Order Switch (on back panel) reverses the order of the Rangemaster Boost and the Fuzz. Normally the order goes Guitar - Fuzz - Boost, but the switch changes it to Guitar - Boost - Fuzz. It completely changes the sound to a very compressed, higher gain type of pedal (it only makes a difference when both fuzz and boost are on).
 
Quality components: Hammond Enclosure, soft click footswitches, Neutrik and Lumberg jacks, WIMA caps and NOS transistors.
 
This is a one of a kind fuzz I built by hand…the result of years of tinkering and delving too deeply into Fuzz Face lore.
I take an ongoing interest in my pedals: If you manage to break it, I’d be more than happy to fix it for you. Also, if this isn't the best or most versatile fuzz you've ever played I'd be happy to reimburse you fully.
