Interesting stuff about the Fogertys and the Fenders in the studio, but Kustom in concert. Makes alotta sense, because the Tremolo is just so pure on the records. Thanks for the info Arjay.

Also, there is some stuff on the net about soldering a cap (I dunno, is that a capacitor?) in the opto-isolater circuit to "bleed" off the noise. Don't think I'd trust anyone to do that right. There was also some dude who was making opto-isolaters with an LED light instead of the neon one that is in there, but I couldn't find anything, and again, it sounds like soldering. Some folks recommended electrical tape around a light leaking opto-isolater but not sure how to do that if it is mounted. And finally, there are some who solved it by moving the lead dress (whatever that is). Note: I might sound like I know what I'm talking about here, but I am just taking the info from the net. I actually have not a clue.

Bottom Line: I'll live with it, unless it starts to have a loud mind of its own. And then it would be off to someone who actually might have a clue.

Your advice is what is important here, Arjay. If you want the best Tremolo, get the Princeton. My lame adjunct is: if you are getting the DRRI, and you're going to play the Tremolo, find an amp that does not make this noise.
