This is the fuzz pedal Hendrix used throughout his career. Mention this pedal to any rabid fuzz nut and you'll hear a flurry of cryptic part numbers like AC-128s, BC 108 and 109s, BC-183Ls, and NKT-275s. Two hours later you've just endured a long-winded lecture on all the different Germanium PNP and Silicon Transistors used in the various Fuzz Faces. While there is much debate over which model is the best, most experts agree on that the Germanium NKT-275 Model sounds the sweetest. Thats said, the Fuzz Face is that recognizable bassy to mid-toned fuzz. It's warm and wooly with just enough edge to make full grown amps melt. These things literally sing and that ablity to sing is what has made this particular model the Holy Grail of all fuzz boxes. Prices on the used market are in the ridiculous range so most gearheads buy the Dunlop Re-issue, and modify them to original specs.
