The Shubb still requires thumbscrew adjustment to get a suitable pressure at different points in the neck. I agree that once set for a particular neck position, operation is simple.

I have used every make of capo imaginable. I have long since dispensed with the Kyser exactly because it has such a strong spring which tends to sharpen some strings. I luckily don't suffer from arthritis but would imagine it to be painful to use for a sufferer.

I use two capos regularly now. One is the excellent Victor mentioned above which actually requires very little force to turn the thumbscrew if properly lubricated. These used to be hard to get (Shoreline Music always had them and still has) but should be more available now that Dunlop has bought the original small company.

My main guitar (a Lakewood), however, has a custom wide neck (almost classical width) and the Victor cannot cope at higher fret positions. For this guitar I use another excellent capo, a Bird of Paradise "Blackbird" (I couldn't bring myself to buy the more brightly coloured but otherwise identical original version!). This is very easy to use (I can change it with my left hand alone quickly) and has excellent reach for higher positions or even classical guitars. Like the Victor, pressure is fully user adjustable via an eccentric thumb-operated cog. I live in Europe but I know that, in the USA, Elderly Instruments stock these.

Peace,
