Well, I put the Frequency Shifter "Lite" behind a panel. I think it turned out pretty nice. This PCB is actually (one of two) for a fellow wiggler, so I will be taking it out and sending it off. However, I will build another PCB for myself, and I will probably break the circuit up into three separate PCBs which are 2" wide and stack them up, as this module is too deep.

Here are a couple pictures. This thing sounds really cool. I'm going to make a video later tonight and post it on YouTube. I will provide a link in my "Doc Sketchy" thread.

A couple details about the build: It has an IN attenuator, an AUX input which is normalled to the SUM/DIFF output for phasing, a SUM/DIFF control which fades between the SUM and DIFFERENCE shifter outputs, and a WET/DRY control which fades between the mixed IN + AUX input and the SUM/DIFF output. It also has a SOURCE switch which switches the modulation between the MOD input processed through an 18-stage Dome filter, or external SIN and COS inputs if you already have a quadrature oscillator you wish to use instead. Plugging other things into these inputs also gives interesting results. Finally, the SUM output, the DIFFERENCE output, and the SUM/DIFF mixed output are all available on the panel.

I hope you're aware that you're posting this stuff in last years thread. Maybe you know what you are doing.

Yes, but I didn't see a 2021 thread, so I just posted. In any case, I'm stuck in the past, so it's appropriate.

So far, a lot of people feel like it's 2020-1 instead of 2021.

So I revisited my soldering on the Rampage and now channel A works too. Mostly. The midrange setting does nothing. Everything else works fine. All the controls on both channels seem to work, so I’m pretty happy about that. But when I select the mid setting on channel A, the rise and fall LEDs stop working and the signal does too. The high and low settings seem to work as they should.

I think the switch is soldered correctly. I’m not sure where the best place to start troubleshooting would be. The only soldering that I haven’t redone is hidden under the sliders and pots. I’d rather not have to desolder them if I can fix this without doing that.

I took out the ICs to redo the soldering. Any rearrangement of the ICs that would help me pinpoint the issue? Could it be a diode or transistor that has burned out?

I think it's time to start your own troubleshooting thread about this, rather than necrobumping last years build thread.
