Plastic feels a bit light

It works as advertised, but the plastic feels somewhat fragile. I'm worried about it snapping if I apply too much force on a stuck knob.

Works well mostly

Does the job perfectly for standard knobs. Had a bit of trouble with a really tight vintage knob, but eventually got it off without damage.

No more scratched pots

Clean removal every time. The lever action provides enough lift without bending the potentiometer shaft. Highly recommend for DIY repairs.

Saved my Les Paul finish

This tool is a lifesaver. I used to pry knobs off with a screwdriver and always scratched the pickguard. This slips under nicely and leverages them off safely.

Essential for any guitarist

If you change strings or clean your guitar often, get this. Makes swapping knobs for cleaning so much easier. Verified purchase.
