Richard, I tried it first through the MP2. And it turns out the guitar signal prefers my Music Man HD130. The tapping technique required is not translating well (given minimal tweak time) through the MP2 at the moment but I need to get several things squared away on this instrument before I can really explore its boundaries. For instance, the guitar neck's intonation is too sharp and the only way to fix it is to shift the neck in its pocket. Likewise, the bass neck needs a shim to make the action reasonable. After those are sorted and with practice, you'll get a more thorough review on my part.
Also, guitar neck is tuned standard, but knowing me I will mess with that eventually to suit my muse at the moment.
