Hi, I used to play a lot live with a Peavy twin amp. It never had a problem filling a room with a nice full distortion. The amp is long gone and I'm playing out again, but am having a tough time getting any amp (whether in practice or live) keeping the full distortion tone at full band volume. I use a 150w Blackstar so it should be able to handle it but gets so muddy. The pedals I use don't make very much difference when I switch it on - which greatly reduces the big sound effect for when a song goes from quiet to loud (Smells like Teen Spirit, Sister Christian, etc). When I play at much quieter volumes at home, it sounds awesome. Any ideas on how to address short of buying a big amp I don't want to lug around? I can't mic the amp at a lot of the gigs we play.
