My roadster crackles/pops in every channel even when guitar volume is off and the only way to rid the sound is the tuner mute or standby. I've changed all the tubes out with ones from my 6505(that work fine) and the problems still there. I also cleaned all the jacks out with deoxit and nothing changed. Any ideas? Also I bought this off a guy off craigslist so I don't know if he had the problem and how long(he said it crackles some times but it's because of the tubes well now I know thats not the case. Btw the amp sounds fine with playing it but the crackles/pops get drowned out with the noise but when you are miced on stage and its acting like rice krispies thats a bad thing. Thx for any help(probably just gonna have to bring it to mesa)-Shane
