Good Morning Delcampers,
In a recent thread about an arm rest, viewtopic.php?f=71&t=90422
, Delcamp member Luis from Brazil shared information about an arm sleeve that has a rigid plastic piece inside of it, protecting the nerves in the arm, and making a comfortable transition over the sharp edge of the guitar top.
I looked around a bit and discovered that this was the Luva arm pad and was available in the U.S. through Luthier Music Corp. in New York City. I ordered one and just received it yesterday. After playing with this arm sleeve for a couple of hours, I am very pleased at the comfort level I have in my right arm. The sleeve slides nicely along the edge of the guitar as I make RH adjustments for tone, and it's very natural feeling.
I have been using an Andreas Abel arm rest which I like very much, but this may be a simpler and more pleasing approach going forward. I'll give you some more feedback after I have used this arm sleeve for a longer time.
Just sharing this for anyone who is trying to address RH comfort issues relating to the edge of the guitar.
