There is a real logic to this... You can get "P" pups in a soapbar shell. I've never tried them personally, but I know they are available.
Now... mere mortals? I'm not sure what that means...
I will say that ALL of you have the same access to PJ that Mike Kroeger does. PJ manages sales and customer support for Spector. When you send an email to customer service, you're sending it to PJ.
And NO ONE has access to Stuart really. He's too busy building guitars and running the workshop and factories. He's the nicest, most gracious guy you're gonna meet... but he's super-busy. PJ runs interference for him.
Spector (the company) as we all know it and love it is a result of both Stuart and PJ's hard work together.
I have to admit that the USA basses are very expensive. And if not for my employee status and resulting discount; I'd not be able to justify affording one. So this is a good point. And I have to say that the Euro models are so good, so well done, that the differences (in my opinion) are few enough that the price on the Euro models represent the deal of the century as far as I'm concerned.
Which I guess comes down to the fact that the USA models are truly "perfection"...
My NS-2JA-R had a bunch of rough frets on the bottom side of the neck, or the side or the neck that faces the ground when playing... and I had to sand them to get them smooth.
There are finish imperfections in my high gloss Euro4LX-Classic and there are none in my USA NS-4... And the brass/gold bridge of my Euro model is wearing through at the corner where I sometimes rest my palm (when playing with a pick... hey! Give me a break... I was a guitarist for two decades before I saw the light and switched to bass)... The bridge on my USA shows no sign of wear what so ever...
There are differences. And they are subtle, small, but they are there. And then comes the knowledge that my USA bass and USA guitar were actually made by Stuart, and the sections that were not directly done by him were done with his close supervision... and they are signed like works of art by him.
All of these things make the USA models special. It is up to you as a player, as an individual as to decide do these things justify paying twice what you could pay for an instrument that I honestly say is 80% what the original USA models are.
For me... the answer is yes. But for many it's no. And that's why I'm glad we make the Euro line. They really are incredible instruments for the money.
