my current set up is a GK RB400 through a 4x10 GK cab. Im thinking about getting something different, not that i dont like my current setup, but i think i could do better. right now our band is not doing any really big gigs so what i have is sufficient for most rooms. i did notice that when we played a bigger room my cab was kind of farting out, really distorted sound. im thinking thhat was the amp at close to full volume not making the cut. im wanting a versitile head but more towards a warm vintage tone most of the time. i play a geddy and a 1980 p bass. i was thinking about looking into eden and ampeg. any thoughts?
