I’ve been using a Blue Chip on mandolin for about two years. Worth the $35? I apparently think so as I have three of them. I’ve got Wegans, a Dunlop Primetone or two, all of which are good picks. But the Blue Chip is a great pick. I can’t say with certainty that the tone is necessarily better than a Wegan, but I think I play better. I’m now even getting picky about my Blue Chips, as I’ve loved my CT55 in the past but now I’m starting to think the TAD60 is a better fit. Will it work for you? Eh, that’s the trick: do you take a chance with $35? Well, if you don’t get it engraved then Blue Chip will give you your money back if you don’t like it. No financial interest, just a satisfied customer.
That said, I don’t use Blue Chips on guitar. I still prefer the ol’ .73 Fenders with a turtle on it, a dozen for $5.
