Swanny,

as to keeping it your main tone - everything but the wah would be appropriate tone for a 'main' sound - at least distorted/overdriven. I would use automation on the wah to tame it somewhat.

In reading your first post - are you somehow using the UX2 for the first amp and effects, then playing through an actual Marshall amp on a clean setting and recording the amplifier mic'ed?

If so, why not record directly from the UX2 into your computer?

I'm just curious.
