Honestly, I think that OF COURSE, the Wersi's can easily beat the sound, in general, of a $1600 arranger...
EXCEPT those pesky Mega voiced guitars... Still got to give the nod to the Yamaha's rhythm guitar sound over just about anything I've heard. While a little on the thin side when heard naked, compared to the Wersi, this makes them sit in most mixes just about perfect, no bass to have to shelf off. Wersi, if that's an unprocessed sound (no EQ added), it's a bit tubby without work (presumably the goal of a built in translator is to sound right with NO work?!
)
There is just such a wealth of subtle noises and performance tricks, that don't draw as much attention to themselves than the Wersi, and end up being more convincing. At least to MY ears. Everybody hears things differently, but if you concentrate on the guitars alone, other than that flamenco piece, I just got to say IMO only.... I prefer the Yamaha's.
The REST of the style? No doubt. That triple scale price hike certainly buys you SOMETHING, no arguments at all..!
