Just got a new Flex 6700 with the Flex Control but the knob had come loose from the controller. It appears there is a small set screw, possibly controlled by a small Allen wrench. Unfortunately none of the ones I have will fit (assuming it is an Allen wrench). Anyone know exactly what size fits the set screw??

OK I think I found another who had this issue and I see comments that a 0.05 inch allen wrench is needed.  I don't have one that small so off to the hardware store . . .

Good, you found it. I had the same problem except my set screw was missing; I bought my FlexControl second hand. I received the set screw and wrench from Flex.  Whenever I have a problem I usually do a search of the Flex Community and sure enough someone else has the answer.
Good Luck and good Flexing

Gotta love those trips to the h/w store for a 30 cent item and $5 of gas / time etc.

The set screw on the FlexControl main tuning knob requires a flat end 0.05 inch Allen wrench, Do not use a ball-end version Allen wrench.
