Top quality workmanship, lovely fretwork, P90s sound great (not a huge fan of the focus switch), smooth neck, looks great.
So why did I return it? Simply too heavy for me: My one was 4kg, which felt like an anchor on the shoulder after standing for 30 mins. These are advertised as chambered, but I think they filled the chambers with concrete in my case! I'm aware the weight can vary, so you might be luckier than I was.
It's a pity that Thomann don't publish the weights for individual guitars like Sweetwater, then you could pick the one you get. Ah well maybe someday....
It's a shame, Yamaha need to look at making this lighter and it would be amazing. In the meantime I'm going to try an SG special p90 at 3kg...
