ElectroSmash Fuzz Face Analysis The fuzz face design was inspired in other contemporary fuzz pedals like the Maestro Fuzz Tone (designed by Glen Snotty) and the Sola Sound ToneBender (designed by Gary Hurst) although the Fuzz Face was an easier circuit than the competitors with only 2 transistors instead of 3. Fuzz Face Circuit Analysis In this video I take a look at a classic guitar effects pedal circuit the fuzz face. I will look at the schematic and explain how the circuit works and how the signal flows through each component. freestompboxes.org • View topic Biasing a FuzzFace The best way to bias a Fuzz Face (or Rangemaster) is to have a single trimmer for the Emitter resistor on the second stage. Instead of using the Fuzz control as the Emitter resistor, use a trimmer, and wire the Fuzz control as a variable resistor in series with the bypass cap (the one normally connected to its wiper). Or, use a slightly higher value for the Fuzz control (try 2k or 5k) and have ... Fuzz Face Bias Resistors Calculator diystompboxes Use this page to estimate the bias resistors of a Fuzz Face circuit. Calculation includes the effect of germanium transistors leakage current in mA, iL text field. Coda Effects Sunface Fuzzface circuit analysis The Sunface is a Fuzzface slightly modified. Fuzz face is really a simple circuit design, as you can already tell by the number of components of the circuit: 4 resistors, 3 capacitors and 2 transistors! The Technology of the Fuzz Face geofex Fuzz Faces per se do not necessarily sound good without tweaking and transistor selection. We can understand this today. I've done a lot of circuit simulation on the FF, twiddling the values of the transistor gains, and looking at the clipping waveforms and resulting harmonic spectra. Biasing the Fuzz Face diystompboxes I have a quick question to ask about biasing Fuzz Face pedals. I know from circuit diagrams and R.G.Keen articles on the Fuzz Face that Roger Mayer used a 2K pot to get the second transistor's collector voltage to half the Vcc. ElectroSmash You can Build the Perfect Germanium Fuzz Face Hiss Noise: When the Fuzz Face is maxed (Vol and Fuzz controls to 100%) some noise is unavoidable for germanium Fuzz Faces. The circuit itself has a tremendous amount of gain and the vintage parts used have some "character" or inherent noise. Usually, the noisiest pedals are the ones that sound best. Perf and PCB Effects Layouts: NPN Fuzz Face There a host of modifications to the circuit you can find on forums and the like, but one I highly recommend is replacing the stock B1k fuzz pot with either a C1k or B2k pot. This will give a better sweep of the range of fuzz. It's also not a bad idea to replace the 8.2k resistor with a 10k trimmer or B10k pot (wired as a variable resistor) to help bias Q2 correctly. Fuzz Central Arbiter Fuzz Face The PCB and Layout The new Fuzz Face PCB and Layout that I have drawn is based on the Axis Face circuit board, which is quite possibly the smallest and most compact Fuzz Face circuit board available. "5F" The FAQ For Fuzz Face Fanatics Small Bear Elec We audit all pairs in the classic Fuzz Face circuit, and we guarantee proper operation in that circuit and with the bias resistor values that we specify. That said, any of our matched pairs can usually be made to work in any of the clones. However, be aware that the bias resistor values in the published schems usually presume that the transistors hit the "ideal" gain range. You can still get ... Germanium & Silicon PNP Transistor Fuzz Face Biasing ... These instructions should also help with other Fuzz Face clones as well. Synthrotek is now testing and bias testing all of the Germanium transistors that we send with kits and completed units. We choose optimum gain for Q1 and Q2 to make sure that proper biasing is possible. Fuzz : Réglage de la bias Guitar Poppa Le terme américain bias désigne ce que nous appelons en français la polarisation d’un circuit, et c’est pour cela que j’ai l’habitude d’en parler au féminin. Fuzz Face™ | General Guitar Gadgets Fuzz Face™ Ready For Transfer Printed Circuit Board Layout – For use only if you are a complete DIY person who wants to etch and drill your own PCB. Otherwise, we recommend you ignore this PCB mask and buy the Ready to Solder Printed Circuit Board or plete Kit from the links below. Silicon Fuzz Face Biasing problem Madbeanpedals I have built 2 different NPN silicon fuzz faces from different vero layouts and on both I am unable to bias the Collector of Q2. The lowest I can get is 6.7V and that's with a 100K pot!!!
