(Variable) Noise Generator complete!

This morning I completed my second noise module.  The one I did previously had a switch to go between white and pink nose, this one uses a pot as a cross-fader between the two. The PCB and all components are the same, it is just a matter of connecting a pot to one header, or a switch to another.

It has been a while since I used my other noise module, so I can't do an A/B comparison quite yet.  But, yes, it does sound noisy. ;-)  I also just used one transistor, and didn't try a few and choose my favorite.  (I thought about it, but oh well!)  The sound is interesting with the cross-fader.  Turning it to the right is a bit like lowering the frequency on an LPF (with white noise input), but not quite.  It gives some interesting flavors of noise at middle settings.

My Input Amplifier and Tuner/Monitor are so close to being finished, but I'm cursed with missing about $0.80 worth of panel parts.  I also have boards to build some more of other modules, but those are competing with my 3-panel Best Of CGS build... most likely I'll jump back and forth.
