I have searched this forum and the PRS site and can find essentially nothing about the 305. It’s like they erased if from collective memory. I don’t know what years it was made, only that mine was made in 2009 and sold in 2010. There are no spec sheets, no photos, no background other than that it was an offshoot of the 513. No schematics, no pickup design information, nothing. It was a $3k+ guitar that streeted around $2200. They sell used for around $1800. And that’s it. YouRube has a handful of rough video “reviews” and all of the ones I’ve seen are quite positive. A couple of magazines drooled over it, but those hacks drool over everything PRS sends them because (a) they are spectacular instruments and (b) their meager salaries come from advertising revenue. I think it is sad that print dinosaurs and rank amateur video bloggers are the only source of information about this lovely instrument. I think mine is a marvelous machine, a model of simplicity, good taste, and solid engineering. I would hate to think that PRS doesn’t feel this way, but that is kind of how it looks and feels to me.
