Hello. I'm looking for xicon's 42tm117-r. Please tell me where they are sold. If you have an extra one, I'd like you to give it to me. 　
If you know a compatible product for this transformer, please let me know. I want to create malekko wolftone chaos.

I’m planning a guitar build and trying to figure out the electronics wiring. I don’t fully understand switches, whether to us a DPDT or a 3PDT on/on/on.

Here is what I’m wanting to do:

HSH pickup configuration. 3-way blade pickup selector, wired Neck, Neck/Bridge, Bridge.

Then a separate mini-toggle: up - middle pickup only (shuts neck & bridge off). Middle - uses only the 3 way blade, for just neck/bridge options. Down - middle brought in with the neck/bridge.

I have an idea how this...

Hi,
I'm repairing at the moment a DOD 670 flanger that has what seems to be a shot SAD512D delay chip.

My pedal has a 110V power input, as I live in Europe and while I'm waiting to solve the current SAD512D situation I'm thinking in replacing the original small 110V primary power transformer for a 230V transformer so I don't need a mains voltage converter.

Just to let you know, theres versions of this pedal where the power transformer has 110V and 220V volts taps on the primary (the available...

Does anyone have a schematic for this, or know how it differs from the Distortron i.e. just bigger caps for ins/out and feedback loop?

ge diodes for sure. put 'em in d3 -8. boom. def what i did on the original.
for the quad opamps, i went with tlc274cn

out of all the quads i had, these seemed to quack and sound the best.

intersil ca3080e's a must

there's new video uploading as i type this. it sounds pretty good. i haven't quite got it dialed in right yet but its pretty close. it even quacks without the fuzz in front of it.

so for mods, i went with a 500k trimmer for r5, which sets the gain of the first stage. turn til...

does anyone here have a Bearfoot Silver Bee and could take some gut shots of it so we can see and possibly trace what the circuit is?

Hello everyone!
Your requests have been heard! I've added three brand new PCBs to my products list 🙂

SLO-style PCB (400mm x 78mm)
Princeton Reverb PCB (322mm x 63.5mm)
Dumblelator PCB (240mm x 35.5mm)

All boards come with full documentation: layout, schematic, BOM! If you want to check out the documentation without any purchase, I've made it available for FREE on my website for anyone to download (just login and you can view/download everything):
If you have any question, please let me...

Pretty surprised to find this official Honey Bee schematic along with a DIY kit:

Might be old news to some, but I wanted to upload the schematic before it disappears.

Wasn't sure if I should bump the old BJF Honey Bee thread from 2009, the values all match up but I guess it is technically a different version. The old thread is a nice time capsule, pretty funny to see comments like I hear Honey Bee's are vapour wear and may perhaps not exist other than in cyberspace;)

I added all the...

Hi all,

Newbie alarm, first post :)

I searched the web for some information but didn't find any build reports for the Vandal from Hell yet.

I ordered a kit of the Vandal from Hell kit from Musikding. The build document is here:

PCBGuitarMan posted a picture of the PCB here on FSB in '21:

In the above thread people wrote that they used their circuit with 12V or 18V power supplies, because the Randall circuit used 24V. But in the build doc of the Vandal from Hell it says 9V.

Also,...

It’s been a couple of years since I’ve made the first Pelota delay: from the very name, it was a circuit inspired by a few popular PT2399 delays, such as the Rebote series, the Deep Blue Delay, and many others that aren’t that different to be worth mentioning.

Even then, with my more limited experience and knowledge, I knew I could try to do better, starting from the awful, noisy, high resistance inverting input stage you find in the vast majority of them that makes you wonder who did it first...

Another Caline overdrive. They're so cheap, I see it I buy it. With this pedal they heavily allude to it being Dumble inspired, and there are a lot of Dumble in a box pedals it could be based on.

Caline came out with e Big Muff clone too, the B-Fuzz , but I haven't bothered to open that up because I can tell you right now it sounds identical to my Nano Muff. What miniscule difference exists could owe to component tolerances.

Has anyone dissected one of the XTS iridium Fuzz pedals? Love the sound demos on youtube.
I have read that it has Red Llama DNA.

schematic? mods?

I got one of these cause they seemed cool. It sounded alright when I played it so I ended up tracing it to see what was going on under the hood. Going off the other pedals by this brand I'm pretty sure its a clone, not sure exactly what it's a clone of but there are some familiar elements. A TS style soft clipper with switchable asymmetry into a two-band Baxandall followed by a JFET buffer. (Yes, I know there's a gate resistor 'missing' from the buffer, it is not a tracing mistake, and the...

he function of D14-15 is pretty unclear to me, they don't add clipping nor affect the volume or tone, so I just keep them in. D11-12 have the biggest effect on the distortion, you really hear the difference when you use a LED or silicon/germanium diode here. D8-9 have the least effect, I mean, you do hear the difference, but it doesn't really change the overall tone, the effect blends in with D11-12.
I use a Germanium in D8, D9 is standard, D11 standard and D12 a 5mm red Led. This gives me an...
