As opposed to a regular single guitar stand, are those stands any better? The ones like Hercules, where a guitar basically hangs from the neck in a locking top holder, and body just leans against rubberised "legs"?
How many times have you adjusted, readjusted your guitar in the old spinning horshoe stand only to go back and adjust it again?
How may of you have used gaffer tape or the like to build up the ends of the horseshoe to lessen the chance of the guitar sliding off.
How many times on break have you repeatedly looked at your guitar during break to make sure it's ok in the stand and not sliding to one side barely hooked on the strap button.
To me, they are more stable.
The old type where the body rests on the "fork" at the bottom are the worst IMO. If you don't set the guitar in them "just right", it can tip out. Not these......tremendous improvement
I recently purchased a triple unit, and am very happy with it
