Notes on Transistor Biasing

I need to wrap my head around this.

Just some notes I found on a few forums.

you’ll want at least a trimpot replacing the transistor collector resistor. Once you get the needed voltage for the collector leg on the transistor then take the ratting of the trimpot and replace it with a metal film or just leave the trimpot on the PCB.

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.
