I just completed this one today. I expected it to have more overdrive (gain) but it does sound really good. i sourced and used the expensive chip (AD823AN). I mounted mine in a 1590B using the logo from the 60's TV show, with a pedalpcb relayed true bypass. It has all top jacks and Wima film...

i just built one and after testing it, i'm not getting as much distortion. Your demo sound like it has more than mine.

i just completed the pedal PCB Zapper (Systech Harmonic Energizer) and mounted it ina 1590B, after also building Aion effects version. They are very similar (sound almost exactly the same) although i personally think the Aion version sounds a little better albeit requires a larger 125B...

i might be in the minority but i think that the Angry Charlie is a very nice sounding overdrive. here's a few pics of my build:

I just finished an Aion Parsec which is a slightly modified Systec Harmonic Energizer ( they added a volume control at the output. It sounds very good (albeit a bit noisy with the higher frequencies boosted). Anyway here's some pics of my build in a 125B with an Aion relayed true bypass...

oops. yeah, it's a 1590BB

the board measurements are: 3.40 x 2.10 inch (86.4 x 53.4 mm) 2 layer board. here's the oshpark page for it: https://oshpark.com/projects/uAvti7FF/view_design

it's definitely a 1590B. i never measrued how tall it is.

I make a decal using white decal paper and design the printout with photoshop, then print it on a laser printer, cut it out with an exacto #11 blade on a cutting mat, then apply it to an enclosure that has it's face sanded with a Bosch orbital sander using 220 grit. I use micro-set to set the...

Just completed this one, a Maestro Fuzztain clone using an EAE PCB from Oshpark. It's mounted in a 1590B with all top jacks with relayed true bypass. I had the original a little while ago and it sounds just like it. here's a pic of the orignal that i had:

thanks!

I just completed building my second one of these. I built the first one in September of '22 with my own acid etched pcb, and a second one completed yesterday from a pedalPCB pcb. They actually sound just slighlty different, probably because i used 2N222A's in my first and 2N3903's in my second...

yep. i sand them smooth and buff them.

it's a clear waterslide decal printed on a laser printer. I cut them out and apply them to a sanded enclosure with micro set and then shoot multiple coast of Krylon matte clear. then i wet sand it with 1000 grit and buff it on a large floor standing buffer with menzerna compond until it a high...

I finally got this one done. It's Aions "Aperture" which is an Ampeg Scrambler. I used 2N5306 Darlingtons (as used in the original) and BC549B's for the BC169B's) I still need to experiment with the internal trimpot (the octave), but it does sound very good where it's currently at in the...
