Palmer Pro Monicon - Passive Monitor Controller - Knob Feel Review The wonderful folks over at Adam Hall knew they had a gem on their hands… So much so, they sent me this outstanding example of engineering to review. Zero Axial Skew, no play, metal material, awesome weight. I’m humbled to be in it’s presence! If I gave out star ratings it’d be 6/5. I can’t even think how it could be improved upon!
