I had that very same pair in my Les Paul Standard for a couple of years after purchase ; and when looking for a great pair of pickups to be 'multi-purpose' yet much better sounding , went straight for a pair of BKP Mules. Perfect. By comparison, the Gibbo ones sounded blocky, unsubtle and lacking real dynamics and clarity. Admitedly I am not a high gain sort of player, but I gather they can handle that ground as well. :)
As Telerocker just reminded me ; - at the time of me getting the Mules, it really was a great chance to start again from scratch, and make the guitar fit whatever I desired. I just felt the Mules sounded like what a good 'Workhorse ' Les Paul should have sounded like.
