Not in English, but actually one of the best demos I have seen with regards to the variety of tones on tap from the 594's. Also I dig the bluesy tones and playing!
I ran across a very lemon yellow 594 recently, kinda like the one in that video above but no darkened edge at all. Not a standard color, so I'm wondering if they just forgot to return back to it after the yellow was applied in order to shoot some brown on it to make a McCarty Burst finish (which is what it was listed as).
