Martin Backpacker is very light and transportable travel guitar. It is bit out of valance when we put strap on the bottom of the neck. I've installed Gotoh Stealth-keys on Martin Backpacker. The original tuners are 200g. Stelth-Keys are 72g (12x6). My Backpacker is now light and well balanced. This tuner is Build-to-order manufacturing. I've waited three weeks even in Japan, where Gotoh is located.
