Musiclily Pro 6mm Steel Hex Box Wrench Guitar Truss Rod Adjustment Wrench for Guitar Bass

It worked. That's the bulletpoint. This is a pass/fail review. I was able to adjust the neck on an early 00s Jackson shortscale bass, despite the fact that it really seemed no tool would fit. So five stars.

Great truss rod wrench. No complaints.

I needed to replace the one that came with my PRS p20e that I lost. This wrench fit perfectly, and did the job nicely.

Good to go!

Very useful to adjust the trussrod of my Jackson Performer !
