    Adding a blend to a Promethium (HM-2)

    @benny_profane Promethium is wired directly to DC jack and so is the blend board. Did some more experimenting today and I isolated the clean signal from the blend and sent it directly to the tip of a separate output which was grounded to the pedal jacks, and there was no distortion bleed over...

    Adding a blend to a Promethium (HM-2)

    Yeah I'm at a loss here... Good news is it gave me a chance to A/B with and without the Split 'n Blend, and there was no difference in feedback or added oscillation. In fact, the SNB is working exactly how it should and this "bleed" is apparently not bleed from the blend at all. It goes away if...

    Adding a blend to a Promethium (HM-2)

    Small update... I realized after toying around with it for a while there was actually some bleed going on, so after playing operation for a while and disconnecting the ins and outs from the Promethium PCB to the blend control and 3PDT entirely, I noticed on dimed settings there was STILL a small...

    Adding sidechain/key input to noise gate

    @bowanderror and @PedalPCB Thanks a lot I really appreciate both of you taking the time to help me figure this out. It is still a little over my head, but I definitely have a better understanding of it now and makes me feel a little better knowing PedalPCB was confused by it too.:ROFLMAO: I...

    Adding sidechain/key input to noise gate

    Yeah I was thinking I would split the input and send one buffered clean signal to the key input of the noise gate and the other to the distortion input, then connect the distortion output to the noise gate input. I don't have a specific one in mind but I was thinking maybe trying to do this with...

    Adding a blend to a Promethium (HM-2)

    Sorry for reviving a somewhat old thread, but I thought I'd put my 2 cents in here since I've been lurking for a while and I've also been trying to figure out how to add a blend control to a Promethium. I built a Split 'n Blend(which is identical to the mask audio blend schematic) on perfboard...

    Adding sidechain/key input to noise gate

    Just wondering how big of a task it would be to mod an existing somewhat simple noise gate, like the muffler for example, to accept a sidechain input to trigger the gating. Im looking at incorporating something like this into a double pedal with a distortion (pomethium) so the gate would be...

    Promethium Filter Question

    Thanks everyone that is what I was thinking too but I got confused because when I was reading a breakdown of this circuit it was noted that there was a high pass filter being formed on the other side of the pot with C8 and R16 when distortion is at max, is that in parallel on the other side? I...

    Promethium Filter Question

    Hello, I'm new here and to pedal building in general and I just recently put together a Promethium distortion successfully. It sounds great, but one thing I noticed was a little reduction in the low end with the distortion knob turned all the way down compared to my original HM-2. I'm aware that...
