Well, as a happy Dave’s customer myself, I’d say you answered your own question.
who knows his contacts, book of business? Dave does. Ask him. Press, ask for his reply, as a guitar nerd, his answer.
I’ve bought a couple Heritage’s from Dave in the pre plaza days. I trust him. If he has your guitar stay with your own past history.
Dave is a guitar nerd like us. Press it.
let us know how your adventure goes. I like your idea, the 530. I bought a Millie DC from him 2004, for one.
