PRS MT15 Mods

This thing sounds great.

But the tapering of the master lead volume just sucks.
It's just to soft or to loud for home use, very difficult to adjust properly.

So that's the first thing I want to change. But I don't know what pot I should insert as replacement. Any idea's?



Here they replace the output transformer.
