A comfortable perfectly balanced strap system. One strap button has been moved such that both are on a horizontal line and equal distances either side of the centre of gravity, this equalises the load on each end of the strap and stops neck dive.
Having the button on the body top counteracts and balances the torque of the button on the back of the neck joint that wants to tilt the bass forwards.
Having the moved button well forward makes the strap hug your right side and pulls the bass the the right which is much needed on a flying V.
Also you can see the new frets at the 25 and 75 cent positions past each original fretslot, therefore missing the old fret slots and the dots.
