@tehn, a couple of my arc knobs have become a bit loose and wobbly. Is this something that I can tend to myself, or would it require sending my arc in?
first off I apologize for the trouble.
everything can be tuned with a 1/16" hex. remove the bottom enclosure then gently tighten the two screws of the loose knob. overtightening can bind up the action, if so just loosen and reset.
if you run into trouble I’m happy to get it fixed up.
No worries! That seems easy enough, I’ll give it a go later today.
