As a guitar player I had been looking for a suitable harmonica holder for some time. I discovered Farmer Foot drums about a year ago, and their product was exactly what I needed.
Expensive, yes but a quality product. adding in the postage from the USA put it way out side my budget.
So I was very pleased to discover that Seydel was now marketing them in Europe.
The main innovation is the magnetic mount, attaching and removing harmonicas can be done with one hand, no clamping or potential scratching involved.
It allows for a closer connection between harmonica and lips.
The holder can be adjusted to suit your playing position and is easy to put on and remove.
Pros - All of the above.
Cons- very expensive.
I would say it's the best harmonica holder for me as a guitar player.
It's a one off buy that should last a life time.
