GK Fusion - knobs turn too easily..

Third world problem? Knobs too well engineered that you have to take a 48Mpixel photo with your hand held computer? 
My main gigging amp head is a GK MB Fusion 800. What's worked for me.
I've a old, large, padded computer carry bag that I found at a Good Will resale shop for next to nothing.
In the bag I added chunks of foam rubber in the strategic areas that come in contact with the sides and certain areas of the back of the head, but nothing contacts the front panel area.
Knob settings seem to stay where I left them at the end of the last gig.
(Oh...and I to have taken pics of the settings with the phone!
)I wish GK, (and all manufacturers), would adopt the detented pots that are used in my other gigging head, a Genz-Benz 9.0. The settings don't move unless you manually reset em.
I've heard of people using o-rings under knobs. Depending on the gap, get some felt and make little washers or find felt washers to go under the knobs.
If you bought that head used,
someone probably sprayed too
much ‘Deoxit’ stuff on the pots.
Ask me how I know.
You’re right about taking a photo.

Those are better ideas than what I was going to propose which involves duct tape.
O-rings for the win. If you’ve got a local Ace Hardware, I’ve found that it’s the best hardware store for small quantity, awkward hardware.
Take your amp in, head to the hardware aisle and pull off a knob. Fit test the o-rings out of the drawer until you find the perfect one. IME, it’s never the one you think it’s going to be!
I always just take a picture of the barcode for whatever I’m getting on my phone and show the cashier. Saves you from having to bag and label every little thing.
Good luck!

The O-rings have it! thank you for playing.
Thanks for tip on the O ring! I have a Fusion 212 Combo (love it, btw!) and had the same gripe.

I'd suggest sending Bob Gallien or Jason at G.K. a e-mail asking if the addition of O rings under the knobs will affect the function of those "push switch pots" that are used in the MB Fusion and Legacy Fusion S amps.
I have gaffe tap on the fronts of all my pedals (not the tops, the fronts - the side not facing the audience. As all my gigs are ampless, my pedalboard is my "amp". Anyway, that's where I put knob positions - to expect gear to travel to and from gigs without the knobs moving is unrealistic - the smart person leaves notes to themselves so they can get their ideal setup. Most any touring band there is some system - tape below the knobs, sharpie marks on the amp faceplate, whatever....works for them so the tech crew can set things where the performers want it - every night. If you don't tour with tech folks (I certainly don't), you gotta do your own setup stuff at whatever gigs you do. Watch some Rig Rundowns, see how it's done, steal a few ideas.
Can't argue with saving settings by writing them down... I will say that another benefit to o-rings that fit properly (can't comment on push-button pots, however) is that they make any adjustments you make have to be much more deliberate and, therefore, precise. Knobs that turn super easily are hard to place for fine adjustments, to me anyway. Having a little more resistance as well as not being able to brush a stray finger across a pot makes these final adjustments all the more easy and confident!
But yes, write your stuff down, too!

The knobs on my Hartke LH 500 are not loose but I wanted to keep my favorite setup in mind so I highlighted with a red marker the settings :
Ditto the felt washers.
Ditto Ace Hardware for small, odd ball parts.
Ditto taking the part with you to the Ace to try.
Ditto simple systems for marking.
Ditto having knobs with some "feel".
Great stuff... you'll have that amp face dialed in soon.
