While it's taken a year and a half for me to get around to this project, I'm really pleased with the results, and so thought I'd share in the hopes that some of you might enjoy, and/or find some useful ideas herein for your own mods.
The PRS you see above was a 2009 Tremonti SE that I picked up used, but in seemingly unplayed mint condition (the SE gig bag, too), for an unbelievable price. Wasn't interested in the stock sounds -- previously had another example of this exact model and year and so was well familiar with what I was buying -- but was wanting a lightweight mahogany electric in a natural finish that I could transform into a guitar that does more or less what a P-90 equipped Gibson SG does...
...Only, without that horrendous (to me) SG body shape, cherry red finish color, non-robust neck joint, snappable headstock, Gibson pricing (new and/or used), etc.
So, one set of made-to-order (and yet very affordable) humbucker-sized P-90s from Q PICKUPS later, a refinished headstock face minus the original signature model branding and plus a less-specific replacement decal, and color-matched personalized plastics as a nice cosmetic finishing touch, and now it's "Live At Leeds" all night long (only, played pretty poorly), and cheap as chips!
The two 'bursts are from the July 300 Collection, both with matching figured maple 'burst headstocks and Starla pickups; Starlas are the PRS version of the Filtertron...brighter and twangier than their usual humdingers. The blue and white one is chambered, with The Artist pickups. All three have the wide/fat neck and they are really wonderful players.
