That's quite an interesting amp, and I'm sure you can get pretty close to the tone you're after with it. The only thing that I can see where you might have a problem, is the distortion. I don't believe that amp was intended for high gain tones. But, what you might want to do is get an overdrive (not distorion) pedal and run it along with the amps distortion. I do this quite often with my amps, as it's like adding another channel to the amp. I personally use an MXR ZW-44 overdrive. Or, you could go all out and get a full on distortion pedal. I can't really recomend any, because I only have experience with a Boss MT-2 Metal Zone, and that didn't work out too well for me.
