Sensitive volume pot on Fuzz Factory

I built a Fuzz Factory some time ago. It sounds great, but the volume pot is way too sensitive. The range of useful volume is extremely small, above nine o' clock it's too loud and below eight it's silent. The current volume pot is 5k linear, what should I replace it with?

It should be a 5K reverse log shouldn't it?

Either way, the volume control is a little bizarre, it doesn't behave like a simple loud/quiet control.

No, it's not that different from a normal volume control. For AC signals, the power line is effectively ground; there's no AC going through it. So you just wire the pot as you normally would, with pin 1 going to the 9V rail and pin 3 going to the circuit, using a log pot. The difference is that the Fuzz Factory uses the volume control as a bias resistor too.

Snip. ..The difference is that the Fuzz Factory uses the volume control as a bias resistor too.

So, it is different then.

Sure, it does double duty in the circuit. But it still acts as a normal loud/quiet control.
