I had a 2011 Ric in JG and it was an AMAZING player, fastest Ric neck ive ever had the pleasure of playing... Dood will testify to how good it was! Unfortunately (sigh... i still miss it) the paint started shearing away from the body near the bridge... And it was only a few months old! So there's definitely QC issues there. Also, the bottom mute pin of the bridge fell out on the way to a gig in the case, that was odd... As id never touched the setup at all! Sound wise it was incredible, all the bottom end you could want, and the VT knob was an added bonus. My review of it is still on BC somewhere.
My current squeeze is a 2002 Ric in BG, and that sounds just like how you'd expect it... Although the neck PU has a weaker output than the bridge one, could be a setup thing perhaps.
And finally my trusty 1982 Ric 4001... That doesnt have any issues... Except that one of the Grovers fell to bits in the case on the way to a gig as well! Lol.
Basically I havent come across any with low E output issues, and ive played a lot of them never mind the ones ive owned... But im sure there are some "did it last thing on a Friday" Rics out there! They've all got *that* sound... And if thats what you want, you gotta find the right Ric.
