I’ve got an American Pro I in three color sunburst and an American Pro II in butterscotch blonde. Both with maple fretboards. To me, the I is a little warmer and takes overdrive like a champ. The II is a little chimier and, kind of like a strat, I have to work at it a little with overdrive. But both sound good to me. Since I got my Kemper, I’ve pretty much gravitated towards playing these the most at my recording computer. I use the Pro I for most rhythm and the Pro II is my lead guitar. I stay in the classic /hard/blues rock world mostly with a Marshall sound. Couldn’t tell you how good they are with other genres. Not sure why they have the series/parallel on the Pro II on a push-push tone pot and not a 4 way, but at least it’s there if you’re into that. And which one would I keep if I had to choose? The Pro I sounds best for what I do. Just my experiences.
