Ah, see... it's a notion of expectations. My wife expects me to find a new Dingwall every few years. I don't believe she probably has an idea of what the cost range of basses are in general, though she understands that they're 'nice basses.' That's not for hiding anything just for her general lack of interest. She's also aware that some of the Dingwalls I bought previously are worth much more than I paid for them.
That's all well and fine, but doesn't your wife sing in some kinda reggae band?
Mine hums tunelessly in the shower. Not much help on the Dingwall front.
