Mid-Fi Electronics Random Number Generator
I’ve always wanted to get more layouts with 7 rows of height 🙂

MXR Headphone Amp
Not a lot of info around, but this one is apparently simple little box that allows you to play at nighttime – without disturbing the missus. Seemed like a quick and painless schematic, but took me a few hours to finish… Sort-of-requested by PaulR. 🙂 I think i won’t be posting anything more today. 😀
4 Channel Mixer
First i thought i’d just post this after the 2 channel version to the same post – but the permalink to that post is “2-channel-mixer”. So. Sorry for “double” post, but here’s one for NoNE. Here’s the revised version with more gain/level from the mixer opamp. I’ll revise the 2 channel version too…
Gretsch Controfuzz
Thought some might want to clone this… 🙂 — *Note: There are a few schematics around. One has B10K pot for “Boost” and other A100K. I put in B100K as that pot due to discussion below.. 100K should make it a bit louder, and linear taper should make the sweep feel, well, louder. But use … Read more
70 Funk Box
Maybe i’ll just post a few today… This i found as a scan from some ye oldee electronics magazine. I have no idea what it does, but text from the article made me draw it 🙂 Excerpt from the article: Fuzz, echo, reverb, big bass, they’re all out! The new guitar sound is funky, and … Read more
2 Channel Mixer
I needed something like this myself, so why not share. I’ve been thinking about building a console for our keyboardist. She has this amazing wooden 70’s Casiotone that i dugged up from trash and it worked. It’s default sounds are pretty bad, but using the organ sound and putting it through Skreddy Lunar Module Deluxe … Read more
Runoffgroove Thor
If i recall correctly, someone requested this a while ago. I think that’s enough for today 🙂 Runoffgroove’s current take on emulating the classic Marshall 100W Super Lead. Read the complete description and history of the circuit from ROG.
Memphis Distortion
When i first looked at the schematic, i thought that there isn’t much point in drawing this – as it is very mildly modded Dist+/OD250 derivative. But then it occurred to me.. There is some psychological thing stopping me from modding a Dist+ or 250. Somehow those seem to be untouchables. So i drew this … Read more
Runoffgroove Tube Reamer
Simplified Tube Screamer workalike. ROG soundclips and info about the circuit: The first incarnation of the Tube Reamer was developed as a stripped-down, yet edgier version of the classic Ibanez Tube Screamer. We removed the input and output buffers as well as the tone control stage, plus implemented a different gain control. Many builders enjoyed … Read more
Dan Armstrong Purple Peaker
Another addition to Dan Armstrong library, The Purple Peaker treble booster. This layout is using two SPDT switches instead of the original setup. You could get closer to the original with using 2PDT, taking the ground to pins 2 & 5, Lo wire to pins 1 & 3, and finally Hi to pin 5 – … Read more
