The only issue I have with volume "knobs" on these modern units is that they are rarely actually a linear based potentiometer like we used to have. Yes, its a "knob" but behind the scenes it just increments a volume button up or down with each 'click' and many times the 'clicking' cannot keep up with rapid changes in the knob meaning the responsiveness in change is no longer anywhere close to what a classic potentiometer would be like.
Also curious to hear if this is a REAL knob or just a simulated knob attached to click-based buttons instead
