Hi there,
I´m a german Moog-fan since many years and I´ve got my Sub 37 (from polish dealer) on tuesday last week - and I´m very happy with it! It´s a very nice synth and I mean, it´s the best Moog, since the Voyager came out.
My little (just cosmetical) problem: The spacing of the Resonance-knob to the panel.
On this photo you can see, that the distance to the panel is nearly 3mm more than all the other knobs, and that looks not so fine for me. The problem is, that the knob didn´t move on the axis of the Reso-pot. On my old Minimoog, I have had years ago, the knobs were fixed with little skrews, but an the Sub 37 there are no skrews for fixing, so I think, that the knobs are just put on the pots. But I can´t push the knob nearer to the panel. I don´t want to push to powerful, because I didn´t want to damage something. … Maybe the knobs are glued?
Any help is welcome … 
Best Regards
Heiko
