What does this do?

This is an analog filter that uses a 10 stage diode core influenced by N. Steiner's Synthacon VCF. You get Low Pass, Band Pass, and High Pass inputs. All of them can be used at the same time to mix different VCOs. The band pass section is what really makes this filter shine.
Some blue lantern improvements include DC removal on the rez circuit, JFET power coupling, and precision trimmers for cutoff and rez.
Through-hole polyester film capacitors where used for the filter.

Does this filter make all the screechy warble like all the other Steiner VCF's out there?

It can if you like that, but I ship it out tamed and very musical. There is a 25 turn trimpot on the back where you can fine adjust exactly how far you want to push the feedback resonance. This design I have does not contain the common dirty pot troubleshoot most people complain about. The inputs also have a switch jack design to quiet any input jack not in use.

If you missed out on the first generation modules I released, here is your chance to see what all the fuss was about.
