Re: What is the best configuration and pups for a stratoscaster you want to sell?
An anecdote: I wanted to do a project that'd be kinda cheap and fun, but wasn't really making for myself. I found a $50 partscaster (mostly squier parts) at a local store and did a conversion on it that was meant to be evocative of Van Halen's "Bumble Bee".
So I put a Frankenstein pup in it, did some painting, did some work on frets and hardware, got a single HB pickguard, and redid the electronics. When I was done, I was really satisfied that I'd hit the mark for what I wanted from my project and thought that somewhere the must be some youngster or fan who'd like this inexpensive tribute.
I did sell it in the end, but after shipping and ebay costs, I barely got back the initial $50 and the $100 for the pup. The other parts and of course my time amounted to nothing, so strictly speaking, I lost money on the deal. Now I learned a bit and it was fun to do, so in cost/entertainment&education terms, it was a bargain, but I could have put a GFS Guitar Fetish pickup in there or even a Fender Bullet HB, and I bet I'd have sold it for just as much--and maybe made a buck or two.
The moral of the story is that i made the guitar that I wanted and thought lots of people would appreciate, when in the end, I spent a lot of time waiting and negotiating just to get it out of my rack.
