I've never owned a 59 set, and I feel like I tell this story too much, but it's just too on the mark here.
I was at a gig at Buckhead Theater in Atlanta a while back. One of the bands on the bill had a guitar player who played a Tele and a 61 RI SG through a Twin Reverb with a Fulldrive 2. That was it. Side note: that started my quest to eliminate pedals and I too now gig with just a Fulldrive 2, after having sold mine years ago and going through the gamut of drive pedals. But that's not pertinent to your question.
Anyway, his tone was incredible. With both guitars. Just insanely perfect guitar tone. Great player, which didn't hurt. I asked him was was in the SG because he was nailing Allman Brothers tones with it.
He said "a pair of Duncan 59s."
I had expected him to say some boutique offering that cost half what the guitar did. No. A pair of 59s, a Fulldrive and a Twin Reverb were all this dude needed to get the tone of the gods. That and a ton of talent.
I still don't own a set. I prefer unpotted lower wind PAF style pickups. But if you can't do it with a pair of 59s, I'll suggest it probably doesn't need doing.
