I have a Korg Toneworks AX300G, and the distortion sounds like crap!! I have tried everything, boosting bass, treble, mids, everything, but it doesn't seem to sound better. I really don't know what to do. The leads aren't a problem, because you can cover the sound a bit with chorus, a bit of reverb and the lead pickup, but how can i make the riffs sound good? It sounds like if you where playing with the lead pickup, and if you try adding treble or lowering basses, it is like a needle in your ears, if you know what I mean. Any Suggestions?
