I thought the preamp was boost/cut despite the lack of center detente (and despite what the catalogues said?)
The pre-EBMM preamp is a boost only type with no detents.
At least that's what I was always told.
If you dial out all the bass & treble it sounds very close to a Fndr. P.
Regarding the "restored white one for $2k: It's missing the the mute prongs and the rubber.
And if he gets $2k for that, then I want triple that, for my original unrestored 77 Inca Silver 'Ray.
(no, I'm not selling, just saying).
If you need to have an original, great go for it.
But I would get a new StingRay Classic Deluxe for less money.
The quality of fit/finish/playability/sound is well worth the money.
They combine the best features of both eras.
And they're made in the USA!
