Funny you changed the pickups, may I ask you why ?I changed the "tarback" ones on my first Custom SG, replaced them with "classic humbuckers" as they called them in 1976, out of pure "ignorance" and ended up using one of them to improve the sound of my 1989 Les Paul Standard ... so maybe these pickups weren't that bad, were they ?
I admit one flaw, the middle PU is out of phase with the neck PU and since they're sealed there's no way one can reverse the phase ...
And did the new bridge really improved the sound ?
In which way ?
