That seems like a lot of money for an ugly headstock. Plus the fan is pretty mild, and you don't get the long scale.
I'd put $500 towards a Dingwall, but I'm done trying to mod basses into something they aren't ever gong to be. I think Dingwalls have spoiled me.
For the price of that neck I could build another fEarful. That sounds like more fun than putting lipstick on a pig.
Have a second 37" on order. Have too many cabs as it is.
Maybe I need another amp.
