I have an early Les Paul Classic, gorgeous guitar, great neck, really like it....but the sound is pretty bright....I've tried BKP Mules, SD 59's and JB's....and it just stays bright, I have a few of these, so I know it's probably partially the wood tone....I've never tried fat cat P90's or P Rails before....I was just thinking if I can't get it done with Buckers, I do like P90's....think that might add some lower end growl to it? If I can't figure it out, she's going up for sale, which would be a shame. Running a modded Blackstar HT60 and a Splawn Quickrod btw.
