I posted this on the Tech forum, but there may not be many looking over there. I rewired my 52 AVRI to modern wiring today, and also did the Fezz Parka mod. Some people have said it doesn't do much, and it's not a real big difference but it seemed to make the tone control works more smoothly, and it get's rid of the funny little hitch you usually get at the end of the tone control travel when you roll all the highs off. Is there any down side to doing the mod? I had a 52 AVRI before that had already been switched to modern wiring and liked it better than the vintage wiring. I tried to like the vintage, but just couldn't. I used the .047 cap, don't know if I should have changed to the .022, but it sounds fine, and the tone control works so smoothly now, I don't know if it would make a whole lot of difference either way. Thanks for the advice Telemarkman, though it took a long time for me to get around to doing the wiring, piece of cake as you said.
