What transistor is used for fuzz?
The usual recommended range for the “classic” Fuzz Face is 70-85 for Q1 and 120-140 for Q2. However, if you like a sound that’s more “squishy” and “compressed,” I have found that a high gain device for Q2 (150-190) gives a good result with a Q1 in the range of 90-120.
How does a fuzz circuit work?
The fuzz face works by inputting signal through a DC blocking resistor driving a transistor one, transistor two is directly coupled with transistor one. This is called a “voltage biasing circuit”.
How do you fuzz bias transistor?
“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).
Who uses a Fuzz Face?
Jimi Hendrix
Jimi Hendrix used the fuzz sound to pioneer his “psychedelic” sound in the late ’60s, and his weapon of choice was the Dallas-Arbiter Fuzz Face pedal.
How do you bias a Fuzz Face?
With the fuzz all the way on (the 1K pot) set the collector of the second transistor to be at -4.5V to -5V or so by adjusting the 8.2K the same way. Listen to make sure you get it right. When biased properly, the Fuzz Face will seem to clean up and get brighter when you decrease the volume on the guitar.
How do you bias a fuzz face?
How many resistors are in a Fuzz Face circuit?
The gist of the Fuzz Face remains in the simple circuit that uses eleven components (2 transistors, 4 resistors, 3 caps and 2 pots) and the astonishing tones created with them; delivering a soft asymmetrical clipping that changes to hard clipping in both semi-cycles under the fuzz pot action.
What kind of transistors are used in Texas square Fuzz?
When allied with the right components – this particular transistor seems to be able to do almost everything! This was paired with the NTE123 Transistor (Silicon) in Cesar Diaz’s cool Texas Square Face Fuzz. Therefore quite apart from the usual NKT275, AC128 and CV7005 Transistors you tend to find in your typical Germanium Fuzz Face pedals.
What kind of transistors are in germanium fuzz pedals?
Therefore quite apart from the usual NKT275, AC128 and CV7005 Transistors you tend to find in your typical Germanium Fuzz Face pedals. You don’t typically see a lot of Silicon transistors in metal can casings – but those there are tend to be found in TO-5 and TO-18 formats.
What is the input impedance of the Fuzz Face?
The Fuzz Face has a very low input impedance that will change with the position of the RFUZZ potentiometer (between 5.2KΩ and 8.4KΩ in the simulation). So the feedback network has a negative impact on this parameter.
