Thank you Jamie, thank you.
One the whole preamp debate, I personally stand by my theory that if you can't afford the 9v USA, the EMG BQC is a better option. It doesn't hiss on the high end (in fact, there's no noise anywhere at all), the center frequency of the treble control treble is adjustable to 4 different freq. centers, and the sweepable mid control frequency selection with the ability to boost or cut whatever you select is a fantastic capability to have on board any bass. With the almost entirely solderless install, it's easy and $139ish compared to $350 (before shipping) is hard to beat.
If I could afford it, I'd have a 9v USA circuit in every 4 I will end up owning, which is three of them, all Euros. That is THE tone I want most of all without compromise. But since I can't afford $1,050 in preamps (and that's before shipping charges and installation which will also consist of drilling out/widening my control knob holes) I'm left with limited options because nothing can 100% emulate the US 9v pre. The EMG BQC is the only thing I've played that comes close, and that's because of the hugely flexible mid control. And in a financial crunch, I'll have to settle for "close." But if you can afford it - the 9v USA pre is the way to go if you want the full-on, genuine, no-compromises Spector tone experience.
What I am thankful for is that these basses (ReBops, Euro LXs) are so much like their USA counter parts in terms of construction materials and build quality and also that they sound so good in their own right. This makes it possible to use almost any preamp that's compatible with the EMGs and it's going to sound good (the exception being the OBP-1 in my opinion). But there's no getting around the fact that the full Spector tone experience comes from the US circuits. I just wish they were more affordable. And if my Forte swap had come through, I would have invested in one for it just to have one fully USA-made Spector that sounded like a USA Spector should.
I am also thankful that there are great sounding options that translate the Spector tone so very well, if not exactly like the USA pre, with the BQC being the closest I've heard, the Aguilar OBP-2 and 3 being a close second.
