MusicNomad Fret Leveler (MN811)

Covers all 22 frets on my 25" scale guitar and 22 out of 24 on my 26,5" scale, but with the natural motion of sanding back and forth with your hand it still sands all the fretboard with every pass.

Comfortable to use and has it's weight as advertised, includes 3 sanding paper stripes. It's worth it to buy a couple of rolls of adhesive sanding paper if you plan on levelling the frets on many guitars. They also sell those here in Thomann, and they're also made by MusicNomad for this tool.

An amazing fret leveling beam.
High quality and easy to use. I highly recommend this product if you are starting on your amateur guitar tech journey.
I can confirm it will cover all the frets on your standard Gibson or Fender scale length necks, so you will have to use minimal movements to do a lot of work. It will save you time and energy.
A word of warning. This is an aluminium product so you have to be careful not to press too hard when fret leveling. If you are using this on stainless steel frets a lot I would be extra careful or invest into a stainless steel beam.

I know it's just a straight edge, but when you feel the weight it has you know it's not going to bed after some time. Also you get some sticky sandpaper strips. MusicNomad has pleasantly surprised me every time and this tool is no exception.
