MusicNomad Premium Truss Rod Wrench - 5mm for Martin Guitars (MN236)

Works perfectly.

Great quality tool. A bit more money than some of the knock offs, but this is definitely quality and works and fits perfectly!

Works great! It's a perfect fit. The handle is comfortable even when applying a lot of force. So far it seems to be unbendable.I recommend this wrench!

This is the perfect tool to adjust a Martin truss rod, I had so buzzing on the first few frets and it was driving me nuts, all it took was 1/4 turn and now thd buzzing is gone and it sounds good.

Exactly what I expected it to be and performed exactly what it was designed to do. You can’t ask for more than that. Good quality tool, especially for the price tag.

It's the right tool for the job if you want to make adjustments to the trussrod and your guitar needs a 5mm wrench.There are plenty videos from the manufacturer and others on how to use this, so be sure to check those out. Small increments are the trick.Tip: before inserting this through your sound hole, cover the edge facing the bridge/saddle with a folded cloth (like an old t-shirt) to prevent any damage.In one of the videos they warn about this, but don't suggest this simple solution.

It's a simple tool, and does It's job. Handle is nice, and the shaft is long enough to work for a Martin.

Works great for my Martin 000-10e acoustic guitar. Honestly, when I got the Martin I didn't realize it needed a specialty truss rod wrench. This has a very solid, quality feel to it. The price is very reasonable. I'd order this brand for any guitar-related gear. I have the Taylor truss tool from them as well. Also good.
