Is there such a thing? PRS famously winds its own Pups. Some of them are designed to be as close as possible to favorite or wonderful pups from the past. Some are just where Paul wants to take them. So, is there ONE pup that can be considered a Signature Pup? The one that defines the PRS sound and vision? I think we should discount artist-specified pups like the Santana, Grissom, Tremonti, etc, as these are not just Paul's vision. I'm thinking more of pups like the vintage bass, the HFS and the dragons. I think it comes down to something like the 408s. What do you think and why???
