The Audition Box

This is a second box meant to make sure that once something is wired up, that it actually works in a new context. A practice amp would work just as well, but sometimes that's not always available in the middle of the night when other members of the household are sleeping. Unit consists of a 1590BB enclosure with both Cab Sim and Amp PCBs inside. Function requires a signal in to feed into the cab sim, after which it would go to the headphone amp for volume and then to signal out jack for listening. 1/4" and 1/8" jacks to accommodate both plugs for whichever headphone and associated plug is available.

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.

The Cutting Board

So the purpose of this tool is to make the "Rock it before you box it" step of pedal assembly and troubleshooting much easier. We're trying to do a couple of things here:

  1. Make sure that every kind of power (different voltages, positive & negative voltage) is available for testing, when appropriate
  2. Make sure that it's possible to not only probe for signal on the PCB being that can be listened to, but also have another probe that makes it possible to inject signal on the PCB. This is because we may not have all parts soldered into the board, or we may want to isolate listing to specific active components instead of the entire circuit. We want to be able to get power and signal into the PCB before it's boxed, and for that signal either to be a test signal, or an instrument. Also want to be able to listen through headphones for late-night efforts, in addition to using a practice amp.
  3. Ideally, once a PCB has been through troubleshooting with The Cutting Board, any problems with assembly will necessarily be with any off-board components mounted inside the pedal enclosure, making final assembly and testing much quicker and easier.
