...i'm missing its ergonomics – and the Dunlop flush-mount Straplocks take my non-headless instruments where my headless one was.
i've been installing the flush-mount Straplock socket on all my Fender and Ibanez solid- and semi-solid guitars – on their lower horn backside.
it allows me to aim the neck upward, in the typical / formal fashion of classical guitar, at which the upper end of fretboard shall align with the player's shoulder bone.
i'll soon be sixty, and i've been playing mostly sitting for the past twenty years – even before i started this major change, my guitars were never hanging low on a long strap, always high, chest-high, heart-high...
...which is where Strandberg guitars' ergonomics truly excel, with all their peculiar shapes and measures – now my current instruments are no longer headless, but i can play them (sitting) in the exact same position of my Strandberg – and i'm happy, happier, happiest at it!
if you're afraid to nick your instrument's finish at drilling, ok, take it to a knowledgeable luthier or craftspeople – still, installing it on your own isn't a big deal, if you observe the drill bit size specifications.
here in Europe, it means you gotta have the two drill bits in imperial size, but it's no hassle to buy them online these days (and you shop online if you're reading this, don't you?).
