I have for sale a Paige Capo that will fit both banjo and mandolin. PM me for price and p+p.
I got it for my Dave Freshwater Irish Bouzouki and it only worked on the 1st fret. I decided to get the Paige 6 String Capo which works fine up to 5th fret. I also use the Dunlop TRIGGER CAPO which works right up to the 7th fret.
Cheers
Ferg
