The introduction of the S2 allowed PRS to re-frame how the public sees the Core line
One upon a time, the Core line was a bold, brash, no-compromise representation of what guitars could/should be. They were forward looking, works of art that remained remarkably consistent in their feel.
The S2 line doesn’t change the beauty or feel of the Core line. But it does make the Core line look older — like PRS’ greatest-hits. Generally speaking, it’s now backward looking. Because of its age, PRS now has a back catalog of models to promote. Strats, LPs & Cu24s are no longer ground-breaking or revolutionary. So, to me, the Core line is retro.
The S2 line is more modern. Rather than using old, wasteful ways of production, the scarf joints, multi-piece necks and flatter bodies are more responsible ways of using resources. The beveled body is plainer than a Core, but also more comfortable. It’s a nod to the times we live it. So in this sense, it’s more modern.
The re-framing is: Core is for collectors and S2 is for workingman players. Thankfully, PRS continues to breathe new engineering into all of its lines, striving to make a more perfect guitar — that’s the defining attribute of a PRS.
Personally, I’d rather buy 3 different S2 models (and have) than one Core model. But that’s me.
