Hi Leo
It has a very clear sound particularly on the bottom end, I know a lot of 6s sound like a nylon up the very top but seem to lack detail and clarity at the B, this is very tight and pronounced at the low B and all the way up keeps the even tone. The top doesn't sound like a nylon string more like a steel or bronze wound acoustic, very ringy and definitely metallic. Whether this is the Overwater circuit Im not sure as I only ever run it mid pan and tones fully on, I presume its a mass and choice of woods thing. Hope this helps?
I think I may have a very old recording of it somewhere, I will try to find it and upload it.
Cheers
Dave
