Someone will be along to shoot me down in a minute, but....
I, too, had wanted a Spector - AND a Stingray. I watched countless demos of the Spector as they are extremely hard to come by in Scotland, and what I ultimately concluded was that, the Spector does one particular thing extremely well, but to my ears, appeared to lack the versatility I was looking for in a bass. It also seems like it might be a bit overpowering in a band setting. Great basses for rock/metal, mind you.
But bear in mind I haven't played one.
