I know, Kevin, I have one. And its big sister, the EB-750, plus the even bigger sister, the AB Super 400, which is thankfully without any sustain block and sounds a million bucks for it.
I was joking (hence the ironic "interesting how they made it look exactly like a hollowbody"). To my ears, the EB-650 sounds so solidbody it might just as well be. It is way too sharp and snappy for a hollowbody, I miss any goodnaturedness in its sound. I should have written: "The EB-650 sounds like and is tantamount to a great-sounding all maple solidbody bass."
The EB-650 has a voice of its own, but its not a hollowbody voice, while the LP Sig actually sounds like a hollowbody.
I'm no friend of sustain blocks in hollowbodies - to me its selfdefeating. I prefer a swinging top even if it invites feedback and is touchier in live situations, there are other basses you cam play in those situations. My best sounding hollowbodies are all without (sizeable) sustain blocks (HÃ¶fner, Framus, Rick 4005, LP Sig, Allen Woody). I sometimes have fantasies of tearing out those oversize sustain blocks out of my EB-650 and -750 and letting those instruments finally "breathe".
