The thing people like me if I had the money and people that do have the money is just they are so damn undeniably cool. It isn't Fender but they are pretty unique and have their own vibe, like it could have been a thing in a different universe where Carlos was around when Fender was. Aside from that his work just looks killer, all of them look amazing and exceptional. Some of it just looks like Leo could have done it and not just in some cookie cutter way a lot of others do IMO.
It just looks like stuff you'd see at GC Hollywood or in a top Boutique Shop. Carlos is a pretty exceptional Masterbuilder as well all things aside and his work shows. He also grew up like a mile or two away from where Abi grew up and not that far from Fullerton either.
You couple that with the family heritage of the Ybarras and the Fullerton connection. You don't just have Ybarras growing out of trees or coming out of thin air, Abi makes what she makes for as long as she can and she's been making pups for the best since the 50s from Hendrix to Richards or whoever else worth a damn who picked up a Fender back in the day. And she's passing on that to her daughter and keeping it in the family with Castedosa.
It's hard to put a price on stuff like that IMO and I'm not surprised they are doing so well, didn't even know but just appreciate the work and the stuff and the heritage/pedigree.
