These machine head guys:
You technically can use a wrench, but you run the risk of dinging your finish.
This cool gizmo by Music Nomad does a lotto things, with one being to snug up those nuts (Wait…that didn’t sound right…but it was).

Wrench is fine, socket set even better
YMMV but IMO this thing is pretty much bad - I got it for free and almost regret it. I did get an earlier version but the blue handle is just too soft and works poorly as a wrench.
Ballistic nylon is bestest.
I just use a deep socket and go finger tight; no ratchet.
I’ve used mine many times. Still going strong. ![]()
Yeah I believe you and I am wondering if they fixed it in a later version. Mine is not good. The metal they used for the driver heads is also cheap and soft, one of the hex drivers has already rounded out.
The screwdriver bits aren’t the best quality, for sure.
With a deep socket, I’d stick some painter’s tape on the lip of the business end, to protect the finish. Of course, it’s doable to not ding anything with a bare socket, if you take your time and are careful.
Six point socket, not 12 make sure it’s a 6 point.
I use this…. works really really well…
Padded bottom, tightens without the need to take off knobs, etc.
Two of my favorite is this EMG

and Stewmac set
But you should have a washer between the nut and the surface anyway, which should be plenty to protect the finish.
Yeah I bout spit coffee on that one. I have this on many occasions in my career as a mechanic
I do cone wrenches from my bike maintenance parts with painters tape over the part touching the bass to avoid scratching.
