Hi all,

Im new to the board. I love building fuzz pedals, but I don't understand how to bias the transistors. I have a feeling some of my circuits might sound wonky because of this... any help would be greatly appreciated!!!

Depends on what part of what circuit you're trying to bias.

in most pedals bias just means use the correct collector resistor so that the collector of a transistor is at 4.5v or half of your V+ power supply. voltage going into the base and other factors all play a role. you can bias on a breadboard using the hit or miss method. or you can just use a trimmer where the collector resistor should be.

Some like to see lower or higher voltages, so I tend to start at 1/2 V and go from there by ear.
