Daddario Auto Lock Strap BK

I bought this strap because of the Auto Lock mechanism which works great on my guitars.
I tested this strap on an Ibanez and a Les Paul and definitely the locking works great.
What is not great is the lack of adherence on the shoulder when is used on heavier guitars.
Because Les Paul is on the heavy side, the strap slides and can not stop the neck dive!
On ST style guitars , like Ibanez RGA, which are lighter the strap does not slides and there is no neck dive.

Bottom line is:
- Auto lock works great on standard strap pins.
- Useless on heavy guitars due to neck dive.
- Perfect for lighter guitars.
