+1 on the TT .. I have a 10" alnico TT my 67 PR and love it.Speakers are key.
My 72 SFPR is currently loaded with a Tone Tubby 10" and is used by our singer/rhythm guitarist with her Tele.
I frigging love that amp. Any brightness issues are smoothed out with the TT. I didn't try many speakers, just got lucky on the first try! Bright amps LOVE Tone Tubby's!
I really did try and squeak by using the PR for live jams because of that ridiculous tone .. but finally i gave into the fact that with a full band jammin' (the way we do)... the PR was not really able to punctuate they way i needed it to. I found myself with less and less headroom and therefore less and less of that sweet tone. I could see it working in a mellower setting, perhaps playing a small bar or the type of gig or music that levels need to be kept down.
Bottom line is it would be a very tough choice if someone said i could only keep one of the two greatest amps ever made! .. but thankfully i don't have to make that decision
