My dear friend, karenk, bought one of these for me after hearing Dick Greenhaus and I talking about them at the FSGW Getaway. Just one more reason for me to love this wonderful woman. This gadget is well thought out, well made, and reasonably priced. 'Catters in the USA (and I imagine Canada) can get one from Dick Greenhaus at Camsco. Dick is, of course, the founder of The Digital Tradition. His prices are very reasonable. He sells them for $18.00 each, or wholesale for $11.00 each (minimum order of 6), and all prices include shipping. If you play at sessions, or open mic's, you really need to get one of these things. I have the Mk II. It is an indispensable piece of equipment. I am going to get them for all my bandmates for Christmas, as well as another couple for myself.
