Guys,
I burned my bass amp out last night, this is a thing that I built back in the 1980's, using some 2N301 power transistors as the finals and I'm surprised it's lasted this long.

I now have a new design that I'm pondering, it has a pre-amp, where as the older one didn't.
What I'm enquiring about is this, I need a potentiometer volume control, I can't for the life of me remember whether you use an A taper (Linear) pot or a B taper (Logarithmic)style thing for this application.

Any takers?
