grats.... nice looking axe too!
I was playing around with my RY set in my Les Paul today, still fairly new to me and especially since I swapped preamp tubes in my Marshall JCM 900 SL-X (I had bought some Amperex, they compressed way too early so I couldn't get that much gain on them and not sound real ugly, I put the RFTs back in).
First, they are potted as well as one could ask. In my four tube JCM 900 SL-X, I turned the gain all the way up and had the MV on 5 and it started humming, the kind of hum you get before feedback, but it did not feedback. On any of my other guitars, it would be feeding back like crazy. On the Carvin which I played right afterwards, I was standing 10-15 feet away from the amp with the gain a little bit lower and it was feeding back like there's no tomorrow.... and that guitar doesn't particularly have a feedback problem either, only in comparison to the Les Paul with the BKP set.
Second, there is not a dead spot on the guitar now with the BKP. Despite being bright wood and bright pickups with a lot of mids, all the strings are about the same volume.
Third, they sound so good for so many things. With my Vox, they're a fat blues tone. With my Major, they're a fat blues tone to a 70s hard rock tone if I want to go deaf. With the modded SL-X, they nail a perfect Led Zeppelin tone all the way up to just being short on gain for the classic Marshall thrash sound such as Testament or Annihilator (one of my mods was to have the gain toned down a little however... if I restored the gain level, they would get there).
