Acoustic Guitar Wrench (Atkin)
Bought this for an Atkin acoustic guitar. Worked perfectly. No need to remove strings while adjusting.

Worked like a charm!
I’ve been rebuilding one of my old electric guitars and the truss rod but had stripped in it and it desperately need an adjustment. Finally managed to get it done once this came in. I love it.

Beware - ESP/LTD eclipses
Rod shaft is too large to fit in truss rod cavity. I'm sure it's great for Fenders, hence the 4 stars, but for headstock like the above, no dice. I did find success taking a 4mm hex and putting it in a latex glove. That was enough of grip to get the trussrod turning. I recommend giving that a shot!

Works as advertised. I like it for truss rods that haven't much wear too...preventative medicine.

Unusable!
The front section is so short it does not reach the truss rod adjustment. What a shame.
