I have a custom 24 I bought used. I am not sure what the pups are, but I read that they should be HFS/VB.
I don't hate the sound, but after playing the guitar for a few months, I am coming to the conclusion that I would prefer a more vintage, less hot sound, more like my ’71 Les Paul custom. Nice, round, mellow but clear. The PRS pups sound a bit flat on the one hand, and overly bright and biting on the other. Again, I can get a good sound from them, or I would never have bought the guitar, but compared to my tele, LP, strats, they seem less colorful and harsher. I don't want them to sound exactly like a vintage axe, just a bit less harsh and mellower. I am mostly concerned with getting a nice clean country/blues/jazz tone. I find I can enjoy distortion just fine with low output pups, except shred, which I rarely play.
I have heard lollers, fralins and wolftones is other guitars, and loved them. I have not heard bare knuckles, but I see they are very popular, paticularly in PRS's.
Others I see mentioned are SD Antiquities and DiMarzio 36 Ann PAF. Btw, I want to change both the neck and bridge.
Just looking for experiences, opinions, suggestions.
