Hey guys, I have this cab powered by a Mesa M-Pulse 600 and recently noticed that it had a lot of static, even at low volume. I had previously only played it in a band context, so the rest of the noise likely drowned it out. My thinking is that it is the tweeter, because when I adjust the L-pad on the back the static gets louder or quieter in correlation to which way I spin the dial. When the L-pad is off (dialed all the way down, I don't believe it is fully off), the static is a lot more quiet but still present. I am sure it's not the amp as it is almost whisper quiet when on and not connected to the cab, but the minute I plug in the cab it gets super loud. Another possibility is that it could be a bad connection between the amp and the cab somewhere, but I have tried both 1/4" plugs on the amp and the cab, as well as both Speakon connections on the cab and they are all equally as noisy. I took off the L-pad panel on the back and inspected the small light bulbs that are there to soak up any excess voltage, and they both are in pristine condition. I'm a bit at a loss here, and because the grill design is different than most Ampeg cabs, I can't figure out how to get it off to take a look at the speakers there were 6 heavy duty bolts through it but it still won't budge with those removed, and I'm a bit scared of shaking stuff around or prying it too much (you get this way after working on German vehicles frequently!). Any suggestions of things to try and potentially rule out certain components, or does anyone have experience taking one of these apart? Thanks in advance guys, gotta get this rig ready because she's gonna be seeing the stage soon!
