Nino, do you know how hard it would be to find the pickups and pre from a USA?
And is the growl from the electronics or different construction/woods, etc?
Hey Jarrhead. Running into you again.
The pickups you can certainly upgrade to. Just Good ol' EMG's if things haven't changed since I got my US Spector (DC's I think (?), mine was made in 98).
The preamp is a different story from what I remember. I was under the impression you could not simply buy the USA preamp. You can get it one of two ways: 1) you buy a USA Spector 2) You need a replacement for a USA Spector and go through an authorized dealer by swapping the defective pre for a new one.
This is what I was told around 99-00 as a measure to "protect", so to speak, one of the unique aspects of owning a US model and obviously paying quite a bit more. Similar to the idea that you can't buy a Wal preamp separate from the bass. Just check with a dealer and see what's up. If you can swap or find one on Ebay (which would be a longshot) then go for it. Gearhead seems to be saying you can buy whatever is now used on the US models so it sounds like things have changed in the last decade since I looked.
As for your original question... I would say go for the Euro but I don't think they sound or feel the same as a US. Not sure how to quantify it but the US models sound like a Spector and the Euro's are a little different. The Euro's have a more generic, albeit excellent, tone. From your other thread and what you say you are going for tone-wise, is the Euro going to satisfy you if it nails the look but not the tone? I don't know but you sounded pretty resolute that you wanted a very particular tone from the BTBAM bassist. By the way, I lot of folks are saying the US necks are thinner than the Euro's. I don't know. Keep in mind my US is over a decade old (when they were still 34 inch scale) and maybe they have made some changes but that neck is not exactly trim! If the Euro is clunkier I could not tell.
I think the Euro's are very well made, sound great, and an excellent value. That being said, after playing the "real thing" for over a decade there is a difference in look, tone, and feel. You are not paying a few thousand more just because of higher US labor costs.
Keep in mind I didn't pay a cent for my US 6 so this isn't an attempt for me to feel better about spending a lot more on a US vs. Euro.
It's a lot of money either way. If you have any questions feel free to PM me.
