Hercules Stands GS-422B+

What a guitar stand, I’m thrilled. so stable and robust. It may be a little more expensive than one would expect, but the quality is invaluable for what it looks like. On one side I hooked up a Fender CC 60 acoustic guitar, and on the other a Fender Player Telecaster guitar.
Here we come to a small problem, although two gum for thin guitar necks come with the stand, my telecaster is quite unhappily held in the stand and it is necessary to put it in a certain position, otherwise the guitar starts to bend as if it will slip. I tried to find a way to reduce the diameter of the holder but I couldn't.
