Title: pot sub question....
Post by: danwelsh on December 10, 2013, 06:43:12 PM
Can I use a 25kb pot in place of a trimpot? I'm building the hipster and don't have a trimpot.

A trimpot is nothing more than a smaller, pcb-mounted pot. So yes, you can use a regular pot (linear).

Thanks a million for the fast answer

You'd get better results in this case by measuring the "good" range of the bias pot and then altering R5 to get you close to the lower end, then using a smaller value pot (say, 10K) for the bias. This will give you some interesting sounds but no dead spots. Bumping a bias knob without noticing and wondering why your signal is dead isn't fun.
