Hey guys!

Im having an issue with my feedback when I'm playing in a live situation where I have to have my amp pretty loud (never goes above 3.5/4 post gain, which is pretty loud on a 6505).

Anyway, you can see my rig in my signature. I run an ISP Pro Rack G and while it does take everything out and "does what it says on the tin" I still get some quick bursts of feedback, and to be honest, it's really getting on my nerves.

I know its not the Pro Rack G for certain. It works perfectly. I am debating wether it could be 1960A cab thats finally had its day. Ive had it for about 5 to 6 years and its been gigged heavily in its life. I've never replaced the speakers or maintained any wiring. I know, I should be ashamed haha. They're not the most robust of cabs in the first place. So, could a wore out cab cause me this feedback?
