This is only the second time that I've bought into the hype of a musical product. This time it was the WCR Darkburst pickups for my R9. Gotta give much love to these babies! My Les Paul actually sounds like what I think a Les Paul should sound like. First off, the RS Kit was the first thing installed when I got the guitar. I kept the Burstbuckers for a while. Neat PU, but a little bright for my tastes and a little harsh on the high end. Next I went with some boo-teek PU's that I used to have in my LP Classic. In the Classic, these PU's sounded great. I was very happy with the sound. But, sold my Classic, kept the PU's and put 'em in my R9. They just didn't work with this guitar. Again, bright & harsh. Then comes the Darkbursts. These sound awesome. I actually hear the acoustic qualities of the guitar. What I mean is the same sort of tone I hear when I strum the guitar acoustically, I hear through these pickups. IMO, my R9 has just the right amount of midrange tone and the Darkburst bring it out in spades! These PU's are the sheee-at!! -Rich BTW, the first "hype" I bought in to was /13 amps. Still my faves!
