Really great, man. I'm in the clouds! And much better with the NE5532 instead of that shitty and pricy hi-fi 2134. But I must go now: Dwarfcraft Great Destroyer is waiting!... :O)
I just noticed that the PedalPCB version of this circuit (https://www.pedalpcb.com/docs/PedalPCB-Mach1.pdf) includes a pair of 22uf capacitors in the power supply section that are not found on this vero. Can you tell me if these have any influence on the functionality of this build?
I built this today. I wasn't expecting much I guess. It's an overdrive, but a nice sounding one. The two 22uf caps on the power were probably intended for power filtering. I didn't see a 100uf on the schematic. Anders probably simplified the noise filtering. Sounds right to me. Thanks
amazing pedal, simple assembly, organic overdrive tone, works perfectly. it looks great on the les paul and telecaster, thanks a lot for the layout, I recommend it!!!
This came out super, thanks! I used what I had: tlc2272, 1N4007s, a pair of 47pf in parallel, 1M vol, 10k linear tone. Extra gain but sounds right. Thinking of playing with the extra diode - DPDT, matched diode one way, odd diode the other, *no diode* might give it a bit of a "Timmy" mode. What do you think?
I've been using this pedal on my board for a while now, I'm not crazy about it but it does everything right, light override, clean/dirty boost, etc. I had a bit of crackle noise when I moved the volume so I decided to open it up. I found some possible solder bridges and a bad capacitor value (47n instead of 470n). Then I decided to look at the schematic, so I went to Aion website and realized that they had just added it to their inventory and that there are some differences with the other schematics available, specifically C3 and C4. In this layout both capacitors (47n and 470n at the bottom) connect to VB and in the AION schematic they go to ground.
So I took the opportunity to test the differences, it's not a night and day difference but with the capacitors connected to ground the gain and mids decrease a bit. Here's a video I made, it's not that noticeable given the YT and phone compression but I think you can tell.

Which one is the correct one? I don't know... Aion doesn't have a tracing journal for this either. I'll keep the caps connected to ground for a while to see how it behaves with my other pedals.
Thanks a bunch! Excellent, I actually sold this to someone, here is my build + some videos: https://hgecontraptions.blogspot.com/2024/10/hge-contraptions-greer-amps-lightspeed.html
Hi all, diy pedal noob here. I'm planning on tackling this pedal as my first project, and in preparation, I've been working on mapping this layout with the schematic available from PedalPCB (https://www.pedalpcb.com/docs/PedalPCB-Mach1.pdf). Much to my surprise I have it almost entirely figured out, but the Gain 2&3, and Freq 2&3 labels on the layout have me stumped. In the pictures I've seen of this build, only one wire is connected to each of those strip-segments (is there a better term for that than "strip-segments"?), and I haven't been able to find a picture of how the drive and tone pots are wired. Is it correct that lugs 2&3 on each of these two pots simply jumpered, and then a single wire connects them to the board? Thanks!
Thanks! For my own education, I've decided to build out the schematic published by PedalPCB (the Mach 1) that shows this kind of detail. I'll post it here for review when done.
Tag it, mate! Perfect. Wonderful sound. Another hundred thanks for the layout. Spot on!
ReplyDeleteWow, you are on the roll! Thanks mate!

ReplyDeleteIts really sweet transparent overdrive and yes indeed it sounds really similar to Timmy. Thank you for the great layout 😁

ReplyDeleteBuild this yesterday, tested today and it works great. I used NE5532 and 47uf caps.

I tested it with opa2134 and NE5532, I prefer the NE5532 because it gives more brightness and clarity to the sound.
ReplyDeleteThe 500K gain knob works better linear. Great pedal!

I’m sure you know all the projects at aion are modded versions of the originals, right?
