PRS Knob Puller Tool

[Moondog Wily]

Just received some knobs from crazy parts, and I have never changed them before. I think I like the microfiber cloth method the best (similar to shoelace), but I am concerned about the top/finish on my HBII getting cracked or otherwise compromised from the pull force. The only tool/method I have seen that would avoid that is the Stewmac knob/bushing puller (it's outer encasement holds in check, the surface from which the knob is being pulled). I would rather not spend $75+ dollars after tax and shipping to pull the knobs on this one guitar (I have no concerns of the wood being bent/cracked on my CU24s). Any thoughts/suggestions?

I use a spoon and a cloth

Two spoons.
Nice straight removal.

I always just wrap the cloth or tshirt under the knob and pull it. This way you are avoiding the risk of finish abrasions. Try it

Don’t know if these would be better? I think the main thing is applying equal pressure around the knob. But worse case scenario, you could send PTC an email and they have some sort of “best practice” in place when they remove them in-house that they can suggest.

Thanks for the replies. I pulled the knobs (insert jokes in replies please) from both CU24s using a microfiber cloth with no issue. After feeling how much force it took, I don't have as much of a concern about the hollowbody top, so I will go for it at some point today on that fiddle! The CU24's look even more fabulous with the new knobs, and the new pup rings on the core finalized it's modifications for now. Still waiting on the ebony rings for the PS CU24 as they were out of stock when I ordered this stuff. Wish me luck on my hollow knob pulling (inserted this last sentence for additional joke fodder)!

I use a microfiber cloth to do this as well. The tops on the hollowbody guitars are thick enough that this process would not damage anything.

Wow, have I behaved myself on this thread.

I deserve a fracking medal or something.

Fracking medals are a bad thing in the states, FYI.

I put a couple of cloths around the knob and pry the knob up with two spoons opposite. Usually little force is needed thanks to the leverage.

I just came for the knob jokes…so disappointed.

I typed “fricking”, but spell checker kept changing it to “frocking”. Now a frocking medal sounds wrong. A de-frocking medal sounds really dodgy!

Let’s just leave it there.

Aye, ya think pullin' your knobs gonna crack your top, all it's gonna do is cost ya money!

Yup. That’s my method.

I swear, it's like no one here has ever heard of a crowbar.

Two spoons, one on each side, used as levers. It’s the easiest way to remove a knob.
