I'm about to attempt to do this myself in the next few weeks. From what I've read, I don't see why not. Really all your doing is swapping out one 9v preamp system for another. I'm not planning to change any pots. My only concern right now is if the active/passive switch will still work. I'll be sure to post how it goes.

The pots in the jag might be different values so you'll need to get (25k I think) appropriate side mounting pots that fit.
I'd also love to put a stacked knob in the vol position to give vol/vol or vol/blend.
