I've got an Amprg SVT-610hlf cab and I've been playing around with the horn to try and brighten up my sound a bit and t try and cut through my 2 guitar players amps (1970's 50 watt Marshall JMP and a 100 watt JCM800). I notice that when I turn the antenuator up to 12 o'clock, the cab just sounds horrid, kind of distorted. One guitarplayer has his prescence cranked and the other has a very midrangy sound. I'm about to lose my mind with this band and I can't seem to cut through sound wise. I own a an SVT-CL that I'm about to retube(microphonic tubes) and have been using my drummers SVTII which I'm not too crazy about. Bottom isn't an issue, highs and mids are. Suggestions??
