I decided to experiment on the built in overdrive, it really doesn't get the job done.  I'm trying to get a better tone.  I've changed speakers and it's not quite right.  It's frustrating when the amp has an overdrive in it and to get a better tone you've got to use a separate pedal.  :duh

Hello Everyone,
I'm ready to do some tone tweaking on the overdrive channel of my princeton chorus amp.  But, I can't find the schematic anywhere.  I have started with replacing the speakers, but it's not quite right.  Any suggestions?
