It didn't seem like anyone had attempted this one aside from the photos in this thread , so here you go.

No secret that it’s an OCD clone. Though which version and if there’s any value changes I’m not sure. Anyone know what diode that is next to the 2N7000s? Looks like a Russian germanium D9K or somerhing. Pedal sounds great.

The Nurse Quacky is a classic, fun-to-build envelope filter that requires no special parts and sounds great. There are a few mods out there like release time switching and whatnot, but I had a few additions I wanted to figure out:

- Filter Drive: Wanted to see if dirtying up this filter was an option.
- Q control: Nurse quacky gets a bit too sharp when used with fuzzed or waveshaped sounds, so I wanted a control to tame that.
- Inverted envelope: This was a stretch goal, but I'd used the NQ...

Found several ended listings of this crazy pedal

Is refered as a Leslie pedal sound: note 2 (!) inductors and one LDR/LED set!

Hi everybody, new to the forum here!
Sorry for my English, I’m Spanish.

I have built a Sola Sound Tone Bender Mk 1 ( I attach the layout I followed and some picks of the circuit) and I need some help with something that is going wrong:

I've been trying a lot of combinations of transistors with Ac128, russians... and I always get the same result:

When I use the pedal with my guitar volume from 0-8 it sounds good (or at least I think so...) but when guitar volume is on 10 it sounds crap,...

Thought this may interest some of you.

You gotta be kidding me...

I’m not a huge fan of the RAT, but I really like the circuit design and have built a few clones for people over time. I decided, however, that I’d build one for myself, incorporating all the basic modifications I know and adding a Blend knob as well. The result turned out quite nicely, and since I’ve been mainly playing bass lately, the Dry Blend seems to work great.

It’s still not my tone, tho :lol:
Here's the schematic with some comments (it might not be 100% accurate because I did a lot of...

hello everybody!
after a long time without firing up my soldering iron, i've recently decided to build a new pedal.

I would like to buy one UV-printed box this time, and i know that Tayda electronics offers this service, but i'm concerned with import-taxes and customs duties, given that around 2 years ago rules changed in the EU.

Do you guys know how much i would pay for a small order from Tayda, taxes and customs included?
OR: Is there anyone in Europe doing UV-printing service with...

Hi,

I bought a broken RV-5 because I thought I could repair it. First thing I noticed is that somebody tried to replace the D1 with another non SMD diode, but I quickly replaced it with the original part. By then, I had noticed the IC6 S8520E33 was hot, so I did the 3v3 stabilization mods, except that I used a LD1117V33 with a TO 220 package (I checked and it seems to be the same as the other one; I couldn't find the SOT 223 package anywhere where I live). I soldered the 1117 with little wires...

Recently i've give a try to some demonfx pedals, since i have not much time to build myself.

The last was demonfx full bb preamp, clone of the two custom shop xotic bb preamp, mid boost and comp versions.
The first thing i noticed when i opened the lid, is that it's based on the single volume pot schematic. That seems not to be correct, as Aionfx tracing journal point out.

The pedal is as usual a copy of the classic ts with a useful active tone section. Is has both the two options sold...

Hi all!

Got this pedal cheap as it 'didn't work' ==> turned out that the LED resistor was loose. The pedal works fine, just the LED didn't work.

The schematic:
As you can spot it is a Ross Compressor clone; as I marked in RED the changes they made to the schematic. These changes don't sound really good...... my unit was really bright and 'Boring' sounding!!

EnjoY!

He sorts his germaniums into low, medium, and high gain. Just wondering if anyone knows what the gain ranges for each of those are? Is his low gain 20-30uA, 30-70uA? Seems like one person's low gain could be another person's medium.

Hi, I'm working on a project of simple DI Box with splitter/buffer functionalities.
The idea is to have a direct unbuffered output and some buffered outputs and ballanced output to send the signal directly to the mixer/audio interface. I want to plug it in somewhere at the beginning of my pedal chain using an input and a direct output, to affect the tone as little as possible, then use buffered output for some other purposes like recording clean signal on my laptop and an XLR output to send...

I got one quite cheap and like it! It really has that 60's Fuzz Tone sound and more, with the added tone control and octave switch.

Enjoy!
