I haven't really had a chance to mess with WHA? Have you? Can you suggest any settings?

I'll tell you a trick though that I sometimes do! I hook up a real guitar crybaby to one of my 'sub' outs, and lead the distorted guitar sound out of it, and then (after looping it through the crybaby), I loop it back to the mic input, and then add reverb and effects. It takes a lot of tweaking to get it right, but it works nicely!
