This includes the two main parts of the adjustable arm, thumbscrew, plastic washer, and rubber washer for the Umbra Tall support.
This arm is the only difference between The Umbra Tall and the Umbra Standard or Umbra Short. If you have a Standard or Short, you can purchase this arm to convert it to a Tall.
I like the concept of the Umbra support system I have the magnets in all three of my guitars, 2 acoustic and 1 nylon string. I can switch the support to either one in a second. I wish the bottom part that rests on your leg was a little wider and would pivot. I like the neck of the guitar further away and the body close to me and in this position the support digs in to my leg. Not terrible for short sessions but a little uncomfortable for long sessions. One of the screws stripped when putting the arm on and at this price point I would expect maybe metal or brass nut plates instead of the plastic but overall I haven't found a better support for ease of changing from guitar to guitar. The suction cup one that I have I like very well but it pops off in the middle of a song so that's no good. So I guess the magnets are the way to go!
The assembly is the same high quality as the rest of the Umbra model and extends the arm exactly as I had hoped. Thank you.
Easy to switch out, just what I needed.
