Although not widely introduced in Japan, this is a brand new, unopened set of ARM brand locking tuners, right-handed R6 (labeled as L in GOTO, etc.) chrome, which are highly regarded overseas for their balance of price and quality. Like Magnum Lock, you lock the strings by turning the dial on the back of the tuner. This model is compatible with the general 10mm peg hole diameter. Please refer to the images for detailed dimensions. In Japan, Musiclily is highly regarded as an alternative to GOTOH, but in terms of price, build quality, and functionality, these tuners feel like they sit between GOTOH (around 10,000 yen) and the Musiclily "Pro" series (around 4,000 yen). I will send them unopened, still in the manufacturer's vacuum-sealed packaging. In addition, I will include one "Fret Wrap" in black, size S (worth about 800 yen), to cut out unwanted string noise and equalize the sound quality of open and fretted notes. ※ Please note that the outer packaging may be either hard or soft depending on the lot (the contents are the same).
