Don't post in this forum asking is there is a schematic or layout or info on XXX pedal.
There is a subforum setup for requests already. It is located here:
REQUESTS FORUM
Any requests posted here will be moved to proper sub forum, and I'll also make nasty remarks about your mother. :mrgreen:
also, if you have a problem with your build, post it in the WORKBENCH. these threads are for circuit analysis only. by all means, if you discover something we should...
Hallo everyone,
Here Gebrey
Im an expert of diy and electronic diy and Ive succesfully made more than 30 effects and some amps.
Whats going on with SHO??
Maybe my chinese supplier gave me fake BS170? Maybe almost all SHO schemes are wrong?
The problem is... volume. It seems that voltage supplied is too less even at 15V.
I barely hear something ONLY if I push 2 Tubescreamer is series into SHO (forced FET by large input voltage signal)
Ive made 5 times this circuit and every time this...
I recently bought a Snarling Dogs Whine-O Wah and it's absolutely amazing. It's the best sounding Wah I ever tried.
But it's really really noisy!
So I replaced all the resistors (with metal film) and the caps with better ones, but no appreciable result.
Next step is to eliminate the extremly loud (probably LED caused) pop-noise.
I love this wah, but I also hate it. It's soooo noisy!! :cry:
Does somebody has ideas for troubleshooting or a solution :D ??
Ladies and gentlemen, let me introduce you the long awaited reverse of what some consider as the best chorus ever made.
It's taken from an original 80's version. I can't tel if the actually made SCF is the same or if there are revisions of the old one
BUT some will have to work a little on it : it was already a hellish work for me to put all that on tracing paper (and did some retouching with graphic editor) and lets say I'm not in the mood to finish all that in any CAD especially considering...
I saw some speculation that the Caline White Heat was a DOD Overdrive Preamp 250, so I found a schematic and compared it to the circuit board, but it I see no potential for it to be a DOD 250, most especially because there is only one diode on the entire circuit board. All of the schematics I've looked at to date involved at least two diodes for clipping, and another one or two in the power supply section. In this pedal it looks like the one and only diode is in power supply section. I'm hoping...
Hi, gang!
For this post, I present a mystery! I have a fully populated FX PCB w/ connected pots that I would like to identify. The only marking is JCW (or perhaps JCW II), and 1983. As you can see in the pictures, the board features a couple NE5532 dual op-amps. I think the two nice sealed pots (both 10K-S, 1/8 shaft) might be original, but the two dual 100K pots probably aren't. I seem to remember Radio-Shack selling that exact same dual 100K (41-step detent, 40% tap). Let me know what you...
Despite having been around for some years, there's still an aura of mystery around waza craft BOSS pedals. What do they have in common, what is the waza factor? What do the custom modes even do?
There's some info thrown around about CCS-loaded buffers, which are nice even if unnecessary for guitar, and they're still just buffers. Is that it?
That said, I have the luck of having a friend who owns the DS-1W and who let me borrow it for tracing without begging too much. Thanks to him, and my hard...
I haven't seen this one here already, so I gave it a trace both for personal fun and curiosity:

Some values aren't there because they weren't marked on the silkscreen like the others, and I'm not going to pull them out to check. You get the gist of it though: they basically doubled up most caps with another one in parallel. The tone stack is a flatter variant. The bass boost literally mixes some lowpassed signal with the tone stack output. The parallel dry blend is done in a...
Hey lovers of the deep tone,
attached you can find my attempt to trace this big tank.
It's my second attempt to trace a pedal so please be kind. I used a continuity tester and the magnifying glass app with the flashlight of my cell phone to get it done. The schematic is made with Kicad.
Unfortunately I don't have a lot of knowledge in electronics. I don't now exactly which component is part of a feedback loop and which is a high pass etc or (and) especially for this pedal which component is...
This one has escaped the forums and layout sites. Switchable 4/6/10 stages, the feedback control is minimum at noon, one direction adds fb out of phase, the other in.
gut shot here:
i thought i'd add it even tho i cant see it being used, its always nice to have more schems and pics on the forum.
for $89 i think its a great deal, i love this effect...it kicks ass over the box of metal IMO!
Hi, gang!
I want to build a couple MXR 6-band EQs, and for a potential source for parts I bought an MXR 1/3 Octave EQ. My question for the group is: are the slide pots in the rack-mounted EQ the same as in the 6-band stomp box? They are marked 100-1040-104 (MXR part number?) and 1378342. Thanks for your help!

Just released today, Jorsh has done us the great favor of sharing both sides of the PCB. Blendable octave fuzz with a cool old-school hand-drawn PCB, shouldn't be a hard trace at all...
I just got my harley benton power attenuator, it comes with a very confusing manual so I opened it up. Can anybody confirm that this thing can run without a cabinet attached while still using line-out?
Hi does anyone have the schematic for the Twin Tube Blue SFX-11 or know the differences of components other than the tubes from the SFX-03 schematic . It looks like they use the same pc board.
Thanks PCB.
I'm back with a new Exar circuit traced :D , unfortunately, I was a bit busy all the time. I traced Exar HV-03 Hoover, and it appeared to be quite interesting inside. Here is what it looks like with a box.

The translation of a pedal description from the user manual:
HV-03 is a device operating on the principle of overloading the input stage of the amplifier. The signal is subjected to the process of compression and extension of the sound. In addition to the...
Hi,
i searched the web but am unable to find a schematic for the Proel DS10.
Not the most sought after effect but i like it a lot and would like to build a few and see if i can tweak it .
A schematic would be a big help.
Attatched are a few gutshots.
