Nice review! and nice bass!
I have a slab body on my pre EB and after years of playing a normal EBMM Ray at first it was a bit strange, 2 gigs and a few practices in and I never notice it, its not sharp like a Ricky edge either.
If your new to Rays in general your in for a treat IMO as you will soon discover more about all this "Its all in the fingers" you hear about all the time, fact is its true! You will soon manage to get most of the tones you are able to from the Warwicks (Styles maybe a better word I'm not sure but you get my drift) just by playing differently rather than dialling them in with the EQ. I love my Jazz bass but it is so easy to rely on choosing front or back pickup rather than playing in a certain way and just cutting/boosting the highs to get where you want to go.
Also the long term Ray players around here have a favourite method of EQing on the 2 band Rays, Bass on full then add treble to taste almost like your using the tone pot on a P bass, trust me its the only way
I now have ClassicRay5 gas even more after your review!
