Sorry to bother you all. But I am looking at a way to pass the hat around so the Dumbloid can be traced. There are a few of us from the Gear page who are curious to see where the origin lies from...
Let me know what I have to do to get this over the line.
I sent a bunch of pics to AG a while back, but I know he has a lot more important things to worry about these days...
Unfortunately I dont have wiring photos (and I can't remember the name of the guy who sent these pics to me....) , but these should get us close. We'll just have to make an educated guess about the pot values and wiring.
I've played these a few times and always liked them.
The usability is insanely bad, you have to have fairy fingers with the stock knobs in order to use the second gain knob. The stompswitches are way to close together.
Anyway, I found one used and picked it up. Was surprised to find mostly through hole components, and pretty well made. Not surprised at all to find a sanded IC. :roll:
I started to trace and to be honest with y'all, I got bored. I did find a few discrepancies with the RC...
Box of Rock variant, with minor changes to cap values Q2/3 source resistors and D-G bias resistor of Q3 so would be quite possible to do a BoR/'59 Sound mode switch with a 4P3T rotary.
I like this more than i remember liking the BoR when i made one years ago, but i just don't like having a single BMP style tilt tone pot and am considering putting a Bassman tonestack on the end instead - If anyone has any advice/suggestions/experience of doing...
Hi Guys,
yesterday a frind of mine give me a Darkglass Duality to try.
I just opened it and shoot some pictures.
It is based on 4049UBE CMOS.
All Pots are 100kB except for the Level Pot which is 100kA.
unfortunately I cannot hold the pedal so I will start tracing the pedal from the photos. In the next few months I will have the opportunity to have the pedal back in my hands and check all the connections. If someone has the pedal and wants to help me, you can write to me in PM.
Getting this thread started. Will come back to it later this evening and update with schematic and pics. I have the neat CAD drawing almost complete, so please be patient for a couple hours, will upload after I'm home from work.
A Kauffman Audio Appliances Aurora overdrive just landed on my bench. I've finished the trace and it's a Timmy with a few parts changed - mostly to the detriment of what makes the Timmy sound great, IMO.
Quick rundown of core differences:
JRC4558 opamp instead of 4559...
Just stumbled across this on the web. It appears to stabilize the effect of temperature on the transistors via a proprietary circuit . Any guesses as to what's going on here?
I am really curious of this circuit.
Weeks ago, I found a review where the owners showed the inside, and the pcb was scripted The Dude .
So, based on a ODR-1 ?
But the tone stack sounds different to my ears...
This has been discussed but there is no definitive schematic here.
The theories are that it's either an Octavia or Bobtavia rework.
Anyone have one for study?
I took a few shots of the TonoMatch ProTubeScreamer.
It is a high quality pedal in mechanical and electrical workmanship.
Jacks with gold-plated contacts.
True bypass with relay and electronic control.
Only film capacitors in the signal path.

This is my first time posting here... I've been trying, for the better part of a year, to obtain this pedal. It beautifully replicates the sound of the Beatles - and much better than premium and expensive alternatives like Aclam's Dr. Robert or Jext Telez's White Pedal (no dis). Hear for yourself! Unfortunately the maker has gone completely AWOL... I was able to get a few replies from him last year but he disappeared. I think he's had enough with making pedals. His website and official social...
Considering only about 50 of the Rockman Ultimatum Distortion Generator pedals were ever released, and having gotten my hands on one for a time, I thought it wise to trace and verify the circuit. I spent a good amount of time, coincidentally with Robert (@PedalPCB) doing a trace of the same pedal at the same time, I took the time to breadboard the circuit based on the trace I made - but without the low-battery and buffered-bypass sections.
The complete set of notes, layouts and schematic is...
I searched for gut shots of this one and didn't find any. So, I am just letting you know that I've got a hold of this one and hope to put up the gut shots this weekend. That is, if anyone is interested... :D
So I had never heard of the church of Tone.
An old friend of mine bought one of my DS1 pedals and he asked me if I were still fixing stuff and I said yes.
He had he said it with an older model.
Didn't work from the day he got it had the Box and everything.
I cracked it open and I looked at the board and noticed there's 2 capacitors missing.
Lo and behold it's the input and the output capacitors.
Now the strange thing is this is the exact same schematic layout as everything that I have...
I give you the W hisper of Screams - a trace of the Kasha OD Guitar pedal. One of the best, oddest, yet simplest, circuits in guitar pedals I've ever encountered.
This post is my contribution to the pedal building community in resurrecting this rare find.
This thing rips and has only two active components - a pair of JFETs. No diodes were used or harmed in the creation of this circuit. Yet, it can can deliver a clean 3db boost, all the way up to...
---------------------------------Due to my inexorable photo skill upgrades I'm able to offer the glimpse in side a pedal I usually just leave on because there aren't any bad settings. Sadly, not only has this got traces on both sides , the designer has fabbed a hyper-secret epoxyblob that plugs into an in-line 8 pin socket. For the xistors, he's used common parts . Q1, Q2=J201, Q3=MPSA13, Q4=MPF102. I'd love to use those chromed, slotted pot dialers in my builds if I new where to get them!...
I am very very new to building effects. I am still in the paint by numbers phase. I am only really building clones with PCBs that are readily available. I am hoping to get a better understanding as time goes on and hopefully make some cool stuff of my own.
Anyway, I have a Kingsley Harlot v2. A friend of mine traced it and made the schematic. From what I understand he changed some of the capacitors and resistors, but the original uses 630v polyester caps and 1/2...
