the weird visual contrast between the traditional Brute knob/fader caps and those new bigger metal-top rotaries used in the Master Filter Cutoff and the Mod Amount. I do like both knob types but those 2 don't seem to mix visually since those are so different in form/texture and color.
Can't help myself from wondering how it would look like with an alternate (more homogeneous) set of knob+slider caps both regarding shape/texture and color (grey instead of white ones).
...hopefully it would look nicer while sounding the same
