Off- topic quick question : Something a little scary just happened to me. I was soldering a socket pad on a pcb, as usual, and something blew up suddenly right in front of me while i was doing a solder joint. Like a tiny micro-firecracker. No harm done, no visible signs on the pcb, the...

If i had to do it all over again, i would be more cautious with the rotary switches, and i would use wires instead of jumpers to connect them to the main board. I wish you good luck !

Hello, I am building DeadAstronaut's F-24 Multi-fx project. It's almost done, and i suspect the two EEPROM sent with the kit are empty. But the project includes a 6 pin header to access the EEPROMs...

Wait ! I still have a big expensive ring modulator with an issue with the sawtooth VCO waveform : https://forum.pedalpcb.com/threads/neurotron-ring-stinger-sawtooth-waveshape-low-volume-no-modulation.20472/

Thank you so much ! A small sheet of paper greatly improves the Manual range, you are right ! I could have done more damage to the circuit by looking for the issue, so i'm very grateful to you ! I also could have wasted lots of hours before finding this led problem. I am so relieved.... this...

Hello, this is my second troubleshooting post on this circuit : i thought it was ok, but it's not compared to other builds. https://aionfx.com/app/files/docs/xenotron_documentation.pdf The obvious issue is that on my build it is much harder to dial some good modulation settings, compared to...

i think i wasn't clear, sry. The Input Gain control does its job, no issue there. I have distortion appearing during the Manual pot's rotation (1rst half). I noticed it when using only the Time output. On the Mono output, it's there too, but less noticeable because of the wet/clean ratio. I...

Thanks a lot for taking the time to record these samples ! I think my build is able to produce some similar sounds. It's probably quite close to total completion. Now that puntygrapes mentioned it, i guess i can hear something like a delay being modified when i turn the Manual pot within the...

Is there a point in the Manual rotation where your modulation fades away ? Or is it supposed to work through the whole rotation ?

Thanks for the demo ! You have modulation with Manual at noon, which tells me something is really wrong on my build.... Your circuit sounds much better than mine. Congratulations for this difficult build !

"Median compressor" ? I really thought PPCB was releasing a clone of Guyatone PS-21 like Aion's Meridian compressor !

Using only the Space/Mono main output, i don't notice any change with stereo/mono switch. No volume drop with the Ring switch, but when set upward, the Time modulation is cut off the mix, i only have the clean signal, and the space/tremolo modulation working. However, using only the Time output...

Understood, thanks ! Longue vie à Feral Feline ! Edit : just did this mod. I first used a 470k resistor across the outter lugs of the B1M Sustain control, and 27k at R8. I had a little statics and scratching noises at the end of the pot's rotation. I added another 27k to the 470k and now it's...

I count 7 values that change between both version. https://aionfx.com/app/files/docs/meridian_documentation.pdf I would look for a big 8PDT toggle, or 2 x 4PDT to add these parts to the circuits. This way way you will have the two versions in a single box. If you are looking to modify a...

The bass specs are the best for both guitar and bass, in my humble opinion. To put it simply, it felt like the guitar version is only cutting off much warmth, much low frequencies in this circuit. In my experience, the difference between the two version sounds similar to turning up the Color...
