Well, thanks, folks. I'm not a concertina person, so after staring at a bunch of picture at Button Box, figured it was a Geordie. Thanks for correcting me! The pitch is relatively high, so I would assume it's a treble. If anybody wants some sound files, I'm happy to make them, but I can't "play" the thing. I'll just be squeezing it and pushing some buttons. It's clearly a lovely instrument, I would prefer that it go to someone who's going to use it well, and who knows what they're getting. That's why I requested an account here. It's still for sale. If there's no interest by the end of the week, I'll go to Craigslist and Ebay.
