Just curious: 1. How is the neck stability on Aristides? Since it's not made of wood, it should be almost rock-solid and you don't have to adjust truss rod during season or humidity changes, right? 2. What about refretting and overall durability? One day even stainless steel frets will wear down. Is it as (relatively) easy to do as in regular guitar and good local luthier would be able to take care of it? Or you'll have to send it back to Aristides or something?
