    I’ve been playing around with my newly setup Tele build. I’m absolutely loving it. The only “issue”, if it really is one, is that at higher gain and volume I am getting some feedback on the bridge pickup. We are talking gain staging two pedals for lead with high volume.
    My Strat doesn’t do this but it is also shielded from the factory with conductive paint.
    I am using Dimarzio True Velvets that are supposed to be double wax potted. I just have to wonder if it’s shielding, just the nature of the beast in a small room with lots of volume, or something else.
    Any ideas?

    Bingo. Although even the most potted of pickups might squeal if exposed to a loud enough pressure wave, it's more likely simple acoustic feedback acting on the strings. I have a Pignose (one of the little ones) that the original circuit blew up and I now power with a salvaged computer speaker amplifier chip - somewhere around 6 watts. Sitting two feet away with my #1, turned a little over halfway up, it tickles my A string something fierce. A little farther away or turning down the volume stops that. My '52 Deluxe doesn't do the same at the same volume, but is less choosy the louder it gets...
    My Squier strat doesn't unless I sit close to the Deluxe, and then it's when I hit an open G (I think; haven't tried for a while).

    Shielding does nothing for feedback unless your rig is somehow prone to oscillate at some multiple of 60Hz.

    Thanks for the info. That all makes sense. It goes away when I cut the tone which seems to further prove that it’s just resonating on those higher frequencies.
