Re: Varible 12ax7 cathode resistor in preamp?

MKB	Re: Varible 12ax7 cathode resistor in preamp? I've considered replacing the cathode follower one stack driver resistor on my mini Plexi with a resistor and pot in series, like Bruce suggested. On this particular amp its preamp had a little too much gain, and increasing this resistor from 1K to 2.2K helped a lot. The gain of the preamp was reduced slightly and it really helped the tone with humbuckers. But sometimes I would like the gain back for single coils, hence the pot.
