This is a bit of a long story about my 2007 R9. It's moral is that boutique isn't always better. I have always loved this R9, and it has always sounded really good. Unplugged, the guitar is really warm, resonant and sweet (one of the things that attracted me to it in the shop where I bought it). But after playing it for a while, I thought it needed just a tad more harmonics. So I put in an RS Tone Kit shortly after I got it, took out the stock Burstbuckers and put in a set of Peter Florance Voodoo '59 pickups. These are really great PAF clones (and often get stellar reviews here). The guitar sounded really good, but I still thought it was lacking a bit in highs. So I put in a Callaham stainless bridge + "mapleflame mod" (longer stainless screws on the ABR-1). The highs I was looking for were still missing. So at long last I made the tough decision to sell it, as I just preferred the sound of my R8 and the R9 just wasn't getting played. Brought it to my tech to switch the pickups back to the original Burstbuckers. It was hard to let the guitar go, so my plan was to just leave it in the case after he switched the pickups back and sell it. When I got to the shop to pick up the guitar, my tech (who knew I was putting the guitar up for sale) said, "You know, this is a really smokin' guitar." I told him about the "highs" issue and he said, "I think it sounds a bit livelier now with the original pickups in it. It's a really great guitar." So I brought it home and plugged it in and, sure enough, the highs that I had always missed were finally there. In fact the guitar sounded incredible! It had never sounded like this before because I had never heard the combination of the BB's with the Pigtail bridge, stainless bridge screws and RS Tone Kit. The BB's were the magic piece of the puzzle. I've been playing the R9 for a couple of weeks now and the sound is everything I want. For THIS guitar, Burstbuckers are perfect!
