Er, knobs. On the AD-20.
First I used Plastic Weld to glue plastic spacers from the hardware store on top of the existing knobs.
Then I just added a couple of hardware store knobs on to those spacers. The spacers made them long enough to use the set screws effectivley.
They have a nice feel and I'm happy with them. Probably won't see field use for a couple of weeks.
Anyone done this?
It was pretty easy, but we'll see how it holds up over time. I considered sinking a little wood screw into the spacer and old knobs, but decided against it.
