i have an old-ish (1990) ibanez artstar (hollowbody) and whenever i put the tiniest bit of distortion on it it just explodes with feedback.

is there anything i can do (besides put a noise gate on it) to combat it?

Stuff it with cotton wool? Do a search, i remember there was a thread where some guy had the same problem with his hollowbody.
