I put one on my 1981 Gibson ES345, some drilling, never regret. Now putting one on my R6 Les Paul VOS, but with the vibramate kit. Personally I think it adds more definition on the high frequencies, works particularly good with Gibson's guitar. Huge Neil Young and Alan Sparhawk(Low) fan, wanted to have a P90 LP with Bigsby for a long time, now I'm happy.
