I more than understand your dilemma. The very first bass I wanted was a Squier P-Bass Special, but in the satin pewter w/. matching headstock. It took me about half a year of occasional searching to find one. Eventually, I got it, but it took some persistence.
There are a couple of walnut Squier Standard Jazz basses on eBay right now, but no Squier P-Bass Specials. I saw a couple about a month or two ago, one on eBay and another on Guitar Center's used listings
, so they are out there. If it's the model you're looking for, and I do recommend it most fervently,
keep at it. One may turn up when you least expect it.
What is the budget are you operating under? As much as I love my P-Bass Special, someday I would really dig putting together a made-to-order P/J bass through Warmoth. Something tough, yet elegant all at the same time…y'know what I mean?
