I installed a K&K internal twin in my Eastman A-model (MD-305), and it sounds fantastic just plugged into the mixer, but even better with my Baggs Para D.I. I'm glad to see Eastman is using these now. The one thing I didn't like on the 305 were the tuners. They had to go immediately (would NOT hold tune, and were just terrible). How are the stock tuners on the 615? While I'm very happy now with my A-style 305, I am thinking of upgrading at some point soon, and while not a huge jump, I think this particular F-model looks to be a good upgrade (I started in 2015, but have been a professional string player on guitar/bass/resonator for 40+ years, and got my mando to play for a gig at the time).
Just picked up a used one for $1000! Looking forward to getting it next week! I’m new to Mandolin… what song was that? I would like it to be the first song I learn :)
