hmmm not really that cool, this is an old Mk1 Mono, and whilst the encoders are mainly built like a tank, the spindles are plastic, and dont take to kindly to the pulling that occurs when you want to take the knobs off. All this levering to get the knobs off is tugging at 2 tiny barbs of plastic. These barbs main purpose is to regulate the heigh of the spindle after clicking down, not to do battle with the handle of a spoon.
Once the spindle decides its coming out, thats it, broken, it'll work mostly, but little bits of plastic get caught up in the base of the encoder, and eventually (during a set perhaps) it will get lodged preventing click dialling and other shady nonsense.
I have ordered encoders from Elektron, my advice is to buy more than you need. Initially, I only needed to replace one - as you can see i need now to replace two. Justin has done this too, and I agree, I will need to dig deep to get through the next phase.
