I haven't played it very much, they said the tubes were not the issue , I dont know what to do the warranty repair shop doesn't have other blackstar amps there to A and B so its hard to show them that its sounding like crap! compared to what i knew it as for 5 months .
online this seems to be an issue, what else should i have them look at?
Speaker, wire, try a replacement cab altogether, tubes, cable from head to amp (Unless it's a combo), cables to guitar, guitar, battery in guitar..
There's umm quite a few things.
