let's do a bit of rational analysis,
- very few guitars have stains that don't fade, some fade more than others.
- 20th anniversary guitar was made in 2005 is that correct? 13 years of fading
- I think it might be well known that the purple dye that PRS uses has been noted to fade more dramatically.
- that particular fading is still quite spectacular, however less spectacular than it was 13 years ago.
- I am convinced that 1st picture looks like the original 13-year-old picture factory fresh spectacular paint job.
I had a purple hazel tremonti looked spectacular the day I received it 2010,, the guitar was left out and played every day never in direct sunlight, but in indirect sunlight and florescent lights.
I sold it in 2016, I took the pickup rings off to look at the pickups, shocking fade. even though it was still quite gorgeous.
it faded to a beautiful completely barely purple almost black-and-white looking charcoal flame with a touch of purple.
so I've definitely seen the purple being the most dramatic fades.
I guess your next question is how much more will it continue to fade as the years go by.
very interesting.
but I think it is to be expected given its age. the seller should have provided you with more current pictures.
I'm sure guitar sanctuary will do whatever you want.
