And to conclude, I corrected the above and pedal works great. Big thanks go to the man, the legend mr @Chuck D. Bones! Thank you for helping out.

I did, Vref is 100% stable with no changes in voltage that my DMM can pick up - stays around 4.4v with general voltage about 8.7V going in after the polarity protection diode. When I say that signal fades in and out it's not slow - it literally takes fraction of a second, it's not slow and...

This one is some previous iteration of this circuit. I'll do more checking just to be sure this isn't some stupid mistake on my end and if I don't see anything I'll reach out to Chuck to see if he would be willing to help. I didn't want to bother him to be honest

You're right, I ahould have made some picks of the underside of the board when it was all apart, will look into that. I checked all components (both placement and values, including measuring all caps before soldering in as they obviously could be an issue). Problem with checking this build is...

Thank you for the suggestion. I went around the board and measured voltages which seem fine - both when board is bypassed and when it's engaged there's constant ca9v present. There's also no brief dip in voltage across ICs when I hit the footswitch. All ground connections are solid and board is...

Hi All, I just build this Mojito Mk3 overdrive based on the attached vero layout from dirtboxlayouts and while it generally works when engaged, the bypass switching is not working well - ie when I hit the footswitch, there is always a bit of delay before the pedal turns on (signal seems to...

I managed to fix this - by upping the value of the 100pf between pins 1 and 8 of the IC to 220pf the oscillation went down a bit and appeared only when the M pot was fully CCW thus shorting lug 1 to 2 which went to ground. I added a 1k trimmer between lug 2 and ground and tweaked it to just...

HI All, I finished building the Bearfoot SYOD V2 on stripboard (4 knob version) and when I set "M" control fully counter clockwise the pedal starts to oscillate at high frequencies. Following all threads I found others struggling with the same issue with no specific solution. It seems the M can...

Yep, musik banzai refunded me for the chip and I bought a genuine one from AionFX and it worked perfectly fine without any noises or issues... :)

I sent them an email, will let you know what reply I get, this is a definitive proof they should pull these from sale as defective stock at least.

Aaaand you were right, I used the IC bought from Aion and it works perfectly. I will message Banzai but would not hope for much, will definitely stay away from their stock and I advise the same to you Guys. Weird how a rather large retailer would stock fakes without shame and price them for what...

Fair point, I have never had issues with the IC's I was sourcing from them (including some of the difficult to get ones like XR2206CP) but who knows. I just got a package from Aion with some PCBs, I got one of their M68315AP to be sure I am testing on a genuine one. Will see how it looks.

From my own build I can tell you will not find a trimpot position where the bleed goes away 100%. It's kind of like calibrating a BBD for lowest noise floor possible. Well done!

Yes, I verified all transistors (have not pulled them out of the board to test but right parts are in the right positions). In terms of CMOS inverter - I was careful and just to test I replaced it with another one I have (bought a couple when I was ordering them from Mouser). I have the same...

Adding a link for the yt video

Thank you for the suggestions. Following your points: - Pinout for the Vreg is the same and I am getting 5V out of it. Just to make sure it's not causing any issues I replaced it but it did not make any change. - Pics + a short video showing the issue attached - I got the chip from...

Hi All, I just finished building the Aion Elysium (Ibanez EM5 Echomachine clone) and have an issue with the pedal having some thumping noise which starts to self oscillate with feedback turned up. This happens even with guitar not plugged in which means the noise gets generated someplace in the...

I second that, I spent more time looking into schematics of this flanger than all other build schematics combined. I need to build the Cheese Source and Brown Source, other than than got the lot as well

Short update - I swapped the ultrabright LED I had installed originally for another clear one with much closer spec to Aion's recommendation and the pedal works perfectly. For anyone reading this far into the thread - mind your LED specs when not buying a full Aion kit! I was an idiot to pick a...
