Title: Anyone ever come across one of these little Yamaha's

The Yamaha VA10 'Busking Amp'

Not bad for a little practice amp thing, the distortion isn't really up to much but not the worse i've heard on a small amp.
The chorus is MN3207 driven and sounds really good.
Delay-Uses a delay chip IC (M65850P) which is cool. Looked at the datasheet and these chips give a 15ms-200ms range.
Amp uses a 12V adapter or you can use those honking big batteries(cant remember what they were now)

I've taken some inside shots as i was curious, some Panasonic op-amps inside aswell.

I do the same thing when I get new gear, I need to see the inside.
