I had my jam session this past weekend and I did fine with the standing up. I may have had my guitar higher up on my body than the others did, but it made it so much easier for playing.
John of MT, I guess you can shred while sitting down. :eek: And Maggior, I do have the dots on the top side of the neck. I will use those for reference. I guess I'll continue to practice standing up more often than sitting. This was a good topic to discuss for me, and I just realized all the GT instructors are sitting in their lessons too so that's probably what led me to sitting also.
