Ok the other guitarist in my band gave me his razorback 255 to look at because it is having a lot of problems with feedback. It plays fine on lower volumes but cranked up and it starts squealing. I tried running it through my noise gate and his (a NS-2 and an ISP decimator) to no avail. I opened it up and took a look at the wiring and I see no loose connections and everything seems fine. It has nothing to do with our amps because we tried 5 other guitars at equal volume and settings (all of which have EMG B1/85 just like the razorback) and the only one that gets feedback is the razorback so any ideas?

Try lowering the pickups, they might be too close to the strings, resulting in uncontrollable feedback.

I'll give it a shot

No, potting is when the pickup is dipped in a substance like wax, which eliminates microphonics.

I wouldn't have though this was the problem though. Is the interior of the guitar shielded?
#8
Oh, and it doesn't have the physical shielding "foil" but I assume that dean used the shielding paint inside as it is flatblack in color and has a metallic appearance when I scrape it
