Toolgirl made this beautiful hack. (and the bit left came in handy too – read her blogpost here!)

Adan plays the ukelele. He also makes ukelele’s. And he and sells them on etsy.
“I’ve been trying to play along with Israel Kamakawiwo’ole’s “Somewhere Over the Rainbow,” which requires either a soprano ukulele or a baritone ukulele capoed at the 5th fret to simulate the soprano-ness of it all. The capo I had on hand was bulky and obstructive when used in this manner, so I bought a new capo over the weekend, a low-profile one designed by Ned Steinberger and made by Planet Waves. It’s pretty slick, and pretty sleek, and allows for very precise clamp force control to prevent over-clamping and pitch increase… but unfortunately is unable to close tight enough to clamp around the extra-thin neck of our uke. So I added some Sugru. Here’s my hand wrapped around it into a “B7” chord shape… plus five half steps!”
