The Eastman 515 CCN is mat finished and is very thin so there is no overspray problem to be concerned about. Maybe I just was lucky to have purchased that 1 in 10000 instruments as suggested above!m and hit the jackpot!
I also find the tuners a little tiresome but not enough to drive me to upgrade them. You do get used to them! Mandolin tuning is always a bit tiresome. I have a mandolin with Waverly’s that is also quirky! Mandolins are like cats, they just do their own thing!
