I don’t know if these are showing yet. I see a box with the descriptor in it. When I click on it, it does open the correct picture. Not figuring out how to actually have the picture show in my posts.
Anyway, if you can view them, the first and third pictures show the knobs from different angles. The black is standard QU fader knob. The white is a knob I robbed from an old A&H GL2 mixer. The red knob is one that I just purchased.
The second picture is a shot of the under side. The slot that fits over the “T” of the fader is ever so slightly smaller on the red knob than the other two. It fits, but takes a bit to get it on and off. After I installed and removed this red knob a few times, it seemed to loosen up a bit.
These are going to work fine for me. It’s not like I’m changing knobs during a show, so if it takes a few seconds longer, that’s OK.
Hope this helps others in their quest for various colors of fader knobs for the QU mixers.
