I have a RebelRelic P bass, built to 1964 specs. Great bass! Could stand any contest with CS basses. The only reason I'm not playing it all the time is that I have flat wounds on it and I play other styles too. If you can get one, get it!
I play my PF50-T with a PF115 HE cab and wonder if adding a second cab might allow it to be louder. Not sure if the second cab should be another PF115 HE or a PF210 for more versatile sound.
