What a Great Product!
I bought one of these because the tunes on which I play banjo in my band are in a variety keys, including A-flat.  Since I only have spikes to tune the high G string to A, B, or C, A-flat requires either tuning the G up or the A down.  I also find that the spikes tend to make the string fret fairly sharp.  This little capo works beautifully, as it allows for easy tuning of the string to A-flat, A, B-flat, etc. without using the spikes. Also, because of how it functions, it doesn't create intonation problems like the spikes.  This is a great, simple-to-use, inexpensive help to any 5-string banjo player, especially anyone who has to play in flat keys.
