The Princeton Reverb is just about perfect in my book. Blackface tone is my favorite, and spring reverb and tremolo are indispensable effects to me. But the reverb and tremolo on my PRRI bother me, to the point that I consider just selling it and buying a BF Champ with a Strymon Flint. Reverb: at least on my PRRI, the reverb has two problems. First, by the time the reverb mix is high enough to be noticeable, it’s making a very noticeable amount of hum. Multiple techs have looked at it and said it’s just part of the design, and while it feels stupid to use a pedal when I have a real spring reverb, the lack of noise makes a big difference. Second, the reverb effect and dwell doesn’t seem as strong/long as other amps (DR, TR). Is there a way to have much stronger reverb that is dead quiet (dedicated reverb tube, etc)? Tremolo: I love the bias vary trem on the PRRI, but have 2 problems with it. First, I really wish I could make it slower and deeper. I’ve seen a video here of someone who did this on a vintage PR, but that’s not possible on my PRRI. Also, when trem and reverb are both on, the fact that reverb comes before tremolo seems unnatural to have the reverb cut out (which wouldn’t happen in a real reverberated room). I wish there were a way to put the reverb after the trem. So, is there a way to buy/make a PR with deeper/slower trem that is before a dead-quiet strong/long reverb, or am I better off just using pedals?
