=== [[Madbean Pedals]] ===
Madbean power board (Road Rage) was first was purchased to be combined with JMKPCBs Testing Rig. Recognized need for 12v power and bought more for a total of 15 in case additional power needs arose. Will keep extra on hand to make 12v and 15v power supplies as necessary. I screwed up and bought the ProtoRig when I needed the ProtoRig Jr. I should be using the ZY-204 Breadboard I have, not the ProtoRig. ProtoRigJr. + the RRBB makes the ZY-204 way more valuable. Unclear what I need, enclosure-wise for Strober and sProbe.

 We thought the mod boards would be perfect for the Theremin Fuzzes as the "spooky 1950s" sound of B-grade horror movies typically involved a warbling theremin and we thought it would be cool to recreate this effect even though we plan on building our own theremin too!  The RC Boxes are like vintage Resistor/Capacitor decade boxes, but even more functional than those decade boxes as with Parasit Studio RC Boxes you can also chain the resistors and capacitors into both RC or CR filters.

 Clean Blend is listed as a test tool to help insert clean tone so distortion tones don't get lost.  Green Octaver is a PC board for the Armstrong Green Ringer. We may include/combine it into a pedal if it strikes us as a good idea. If, after testing, the inclusion actually ends up making a pedal better, we'll keep it in there.

 The Burger Feedback Looper is a small PCB which is used to loop a signal and throttle it (using a potentiometer) back into itself, tweaking the ability to create more noise. This little looper PCB is obviously intended to put into an enclosure and make another control available on the pedal. We're not really clear right now where this control would be applied, but we're willing to experiment a little and see if this is a worthwhile endeavor.
