MusicNomad Premium Spanner Wrench (MN224)

I have a similar non-name tool, but hesitated to use it because the metal scratches. The Music Nomad version has a soft pad to install underneath to protect the finish. The machining is also superior to my generic one, and it grabs Gibson toggle switch nuts perfectly. Now I don't know how I got by without it.

This is a great and very practical tool to tighten loose nuts in a pinch. Its thin profile allows it to easily fit under knobs and strings. I like the fact that it comes with a felt backing, though it is possible to scar the instrument if you are not careful, I did when using it in a hurry.
The price is a little steep but the quality is excellent and it can be a lifesaver.

The primary reason why I bought this spanner wrench is the protection under it, which prevents damaging the surface of the guitar. I use it primarily to adjust the bridge on my Les Paul. I also use it to tie all the other nuts. So it is very useful.

For professionals and amateurs. If you like guitar maintenance, it's something worth buying.

Used to remove guitar knobs, and it works perfectly. Feels solid and well-built, grips the knobs securely, and allows removal without slipping or damaging the finish or hardware.

A classic tool for tightening and unscrewing all the unconvinient things on your guitar.

Soft surface of the bottom is a nice touch, protecting the finish of your guitar.

Everybody should have one of these if they play regularly.

I recommend this tool for all guitar owners. Very handy and useful.

gets in places other spanners can't and its super small and light. good felt also

Absolutely great to have and use
