Ergonomics, strap on a bassguitar and stay happy!

Most guitarists complain about the strain it gives to play their guitar all night long.
Complaints range from muscle-ache to severe chronic tendenitis. A good guitar design takes this in to account by reducing the weight, balancing it and by placing knobs and tuners so you can reach and turn them easily. Have a look at the grandfather of bassguitars, the Fender JB and you'll notice at least one flaw quickly: tuner knobs are placed in such a way that it is very hard on the shoulder to turn them in that angle. My Tune solves this partially by placing the tuner knobs angled back. Because I designed my headstock slotted I am now able to place the tuners in a zero degree angle for quick and easy tuning. Inspiration for this choice is the double bass headstock. Later on I discovered the site of the Bolin NS5 bassguitar, so I am not the first to do this. Anyway this blog is not about me as an inventor...
