I've been playing this for a few years and love it. By far my favorite Belton driven verb. I traced it out and here are my findings. I have a few components I've done my best on but list them if anyone knows better. I built it on a breadboard and it sounds identical to me.
D2 measured at 0.6vf. Since its just a SHO boost I'm assuming its a 9v Zener.
C14 measured at 100u but i did not desolder anything. That seems crazy large. Maybe you can read the code on the cap...
I've been planning to clone this pedal, and I have a general idea of how it works and could probably spin something up (though I'm a beginner in electronics. I only have first year college level of physics knowledge), but I would like some guidance and pointers from people better than me, or better yet, a tracing of the guts. I might still modify it to fit my personal uses, but covering the initial ground on would be good.
Here are some pictures of my personal Dunwich Wizard Fuzz #85. As it's quite a rare and now unobtainium unit, I decided to trace it.
I carefully took it apart, unsoldered all components, measured the resistors with a multimeter, measured the transistors with Atlas DC55 and noted everything down.
Then I traced it using Illustrator and drew a schematic on Kicad. I made sure my schematic doesn't contain any error, as I redid the original pcb layout on Kicad.
Is anybody interested in tracing the Aguilar Octomizer?
I have one a long time ago, and tried to trace it myself, but don't have the time and knowledge to do it.
I degooped the little secret part of the PCB, but I'm afraid I scratched too much and deleted the marking on an IC. And there is a smd diode broken too, that I think it's a dual smd diode, kind of 1n4148.
I can messure any resistor or capacitor, or desolder too.
Here it's a shared folder with...
the original 1176 is crazy expensive these days. i thought it'd be pretty elaborate, but looking at the original 1176 schematic, seems like a couple JFETs and a some BJTs. presumably the pedal removed the 5532 differential input. and the marketing doesn't mention any transformers so i guess they skipped that too. runs on +30V and -10V, nothing too crazy.
they're charging $359 for a pedal clone, and i bet most of that price is just based on the...
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.
So I found these pictures on the ss/bs blog, located here:
The pictures should give someone a good start, and the other image should give all of the part values. I'm not sure what the changes were between versions. I tried my hand at figuring this out, but didn't make it too far. I figure I'll leave it to someone more experienced. There are some more pictures on the blog that I haven't attached.
Fast forward to 10:35 for the up close board shots.
Brad The guitologist just got his and takes one apart. Its hybrid smt thru hole, sounds sick as shit.

I did spot a sot23 n ch mosfet labeled mv near the clipping switch it also looks to have LEDs in the feedback loop
Hey FSB members, I haven't seen much discussion in the area of Pigtronix and I feel that they are coming up with some new ideas as far as effect pedals go. This is their compressor pedal, actually a limited edition version. The only thing that's different, from my understanding, is that a germanium transistor is used in the GRIT engine in this particular version.
I really like the way the switch and jacks are connected, seems reliable to me? :block: It looks to be extremely difficult to trace...
This is the newest version, which adds a charge pump for 18V operation and drops the Grit distortion section, essentially the same as turning the control all the way down on the original.
There are some very minor component changes from the original Philosopher:
Tone cap from 6n8 to 1n5 - pushes the frequency from 2k up to around 8k
Sustain pot increased from 25kB to 100kB - this was...
There was an earlier schematic traced from the Demonfx ripoff , but since it's technically a different pedal and the name is spelled wrong in the thread title, I figured it would be better to start a new thread. My trace has some slight differences in component values - which could represent either measurement errors from the Demonfx trace, or errors from Demonfx when they traced the Darkglass. But overall the...
The Magpie Octal 21 is a clone of the Combs JJ-150. The circuit is an attempt to to emulate a Gibson EH-150 amp with octal tubes. It goes from Charlie Christian to Junior Barnard.
I checked the connections twice and also double-checked the values. The numbering doesn't follow the PCB at all because the PCB numbering is buried under the components.
Here the voltages, all measured against circuit ground (not DC adaptor ground), pedal on, switches off, knobs at 12 o'clock
Hi friends!
Is there any information on ProAnalog Fuzzes? I think they were top as for representing traditional rock / blues rock sound.
I found the layout on one of the forums and assembled it on
a pref board using old military soviet germanium transistors. It really sounds excellent.
I have one of these and don't get much use out of it. Thought i would post gutshots before i sell it. Circuit is simple enough but the offboard wiring is insane as there is an LDR in the feedback loop section, 3 mini toggles, 4 jacks, 2 LEDs and 5 pots.
I had a bit of trouble rendering the offboard wiring without pulling the whole thing apart, hopefully these shots are still useful.
Circuit:
The aluminium case transistor is 2N2222 and the 2 black trannies are 2907s. The resistor...
Here's a fun tremolo! It's a pedal I had for a while, I didn't took the time to trace it until now.
The board is kind of a mess but I proceeded carefully.
Of course the chip names are sanded, but the 4017 is quite obvious. For the double op-amp, anything works pretty much, I tested the TL072, RC4558 and LM358.
The stop switch is for stopping the clock, a bypass is still needed. This switch is part of the 3PDT bypass footswitch. When the pedal is bypassed, the stop switch is closed.
The logic...
Anybody have a schematic for the Luxury Drive? I've been wanting to try one out for ages but can't seem locate one where I live. From what I've seen in pictures, it seems like a simple circuit.
