Essence of Simplicity
I had this exact same capo years ago.
I have a Guild 12 string, a Gibson SG, a Steinberger Headless and a Strat and it fits all of them.
Small enough to fit in your pocket, and fully adjustable.
The same capo is available in a "flat" model as well.
I am really glad Dunlop still makes this unit after all these years, after all why mess with perfection?
