Anyone else but me NOT like the sound of morado when slapped? That's the only dig I had with my prior Metro's. Sort of an unpleasant 'gank' in the uppermids. IME/IMO of course. I will say that, to me, there was something special in the mids about the brazilian rosewood NYC PJ5 I recently got rid of (like an idiot of course!).
Morado, again to me, sounds closer to maple than what most think of as a 'rosewood board' sound (to Roger's point... harder, brighter, etc.). That upper mid gank is VERY similar to what you get with a maple board (which I like with an ash body... that classic funk sort of thing).
I like Morado so much because it sounds much brighter and more aggressive to me than rosewood (and even 'feels more' like maple to me... hard, shiny, not porous, etc.)
If I was sourcing an alder/RW bass and wanted that more mellow 60's vibe, it would be Indian Rosewood for me all the way (or Brazilian or Madagascar or whatever if I wanted to pay a little more).
Per Roger's post, I am surprised that Morado costs more than some Rosewoods. I would not have guessed that, given the wide use of Morado (it seems) on some moderate priced instruments.
Anyway, the Metro RV's are on the 'bright and aggressive' side of things to me. That, IMO is due to a combination of the relatively aggressive Sadowsky pickups and circuits... and the brighter, tighter tone and bounce of Morado versus the more standard Indian Rosewood that most associate with a 'late 60's type' J Tone or the Brazilian boards that most associate with earlier 60's type J's.
Pure IMO there. I like the RV's specifically because of their brightness and that bit of 'maple bounce' you get with those boards. If I was truly looking for a 60's vibe, I guess I wouldn't look to Sadowsky basses at all, but that would be another discussion (i.e., even my alder/Madagascar RW NYC Sadowsky J, while great sounding, sounded closer to my ash/maple Sadowsky than it did to my alder/Indian RW Alleva... that REALLY sounds like an old 60's J bass to my ear).
