I normally use one of the large, rubber-covered, L&H ergonomic tuning keys where the rubber doesn’t taper at all. On an older Style 22, though, there are one or two tuning pins on the 1st or 0th octave that are close enough together that the larger key doesn’t quite fit comfortably between the pins. A smaller T-shaped key I have (where the rubber coating does seem to taper down more) will fit into that space fine. Is there a version of the ergo style that has a narrower rubber coating, and / or has anyone played around with trying to shave down part of the coating somehow?
One other question: most of shops sell both a “regular” tuning key holder (to attach to the harp handle) as well as a pouch specifically designed for the ergo one – will the standard holder work only with the smaller T-shaped keys, or will it work with either?
