I've owned my R7 for a few months now, and while it sounded good, it wasn't <quite> as good as I thought it should be. It played WONDERFULLY, but it didn't have as much sustain and punch compared to my buddy's R8. I chalked it up to the differences in wood, and focused on messing with new pots, caps, pickup height, etc. to try and maximize what I had. Tried 11's, 10's, and even though I had always checked the intonation I had left the action "as is" since it played so nice. All made improvements, but acoustically it still wasn't where I wanted it. Then, I thought back to when I played my friend's guitar, and I remembered his action was just a little higher than mine. So I busted out the ruler late last night and measured...a tad less than 2mm on the bass side, 1mm on the treble side. Hmmm....raised it to a bit over 2mm and 1.5 mm. Retuned, and WOW! There it was. The sustain and punch was there, even without plugging the guitar in. Chords just rang out, and single notes were full and singing. I plugged in to my Budda SD 30 today, and it was a different (and improved) guitar. What I heard acoustically translated into fat fat sustain with a nice bite. There was a clarity that was missing before as well. It still sounded like my guitar, but everything was better. I couldn't stop playing-the guitar sounded amazing. I quit only when my fingers got tired. The trade off is that it's a little stiffer to play (could be the new strings though) and I have to work a bit more for the notes, but man, does it sound good!
