Back on the Tarr subject, I just brought it home last night from Arnold's with its new chromatic C-Extension, beautifully made and mounted if I may add. With the Season just about over, I might try it on one of the summer concerts and see how I get around it. I just have to do a few personal tweaks with the set-up, as usual.
As soon as I can get my son Mike to take some pics and get the page up, I will fill in its data and have it posted on line. This particular Tarr is a piece of British history.
