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...
Morecowbell, thanks for those great links you posted, but if they are all avaible from one location, it's better to just post that one link. If people are interested in discussion about this or that box, that can become a separate thread.
They are all in the $59-159 price range! Anybody has more info on this brand, we're still waiting for the english version of the website..
Hi everyone, I'm very new here, in fact first post. I wasn't quite sure how to start a new topic so I'll start here.
OK, I have managed to pick up a YAMAHA SB200 Effects box. It's had a bit of mangling along the way but I hope to restore it to near original condition.
I've kinda trawled all over the internet for the cct/wiring diagrams but no luck except for some photos etc, and of course, this thread.
It's not the individual pedal schematics I'm after - that will happen later, but the...
Hadn't gotten around to post this one yet.
Another cheapo, yet not awful-sounding one.
The circuit does not seem to stray too far from your standard OD. It has a fairly flat freq response but a limited drive range.
I'll get around to modding it at some point, but the bastard crapped on me shortly after reassembling it and I couldn't be bothered to reopen it.
Trace double-but-not-triple-checked. Pinch of salt, etc.
We still need to clean up drawing and verify stuff and we don't have means to measure caps atm, but long story short the blow torch is an OPA boosted Si NPN fuzz face (q9/10) with some modded values running at 18V. Torch button sets pre boost gain and there's a weird looking double transistor buffer (q7/8) between OPA and FF that we don't quite understand yet, maybe we missed smth or got it wrong? There's also a 2nd order passive filter after the FF/before the active EQ which...
Hi,
I disassembled a Rocktron Surf Tremolo with the problem that you can see in the video:
The problem hapens even in bypass, it was just a kind of amplified when the compressor is on.
It was not an easy pedal to disassemble, and the board its heavy populated mainly SMD components....I will need some help, and if anyone have the schematic...
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 recently received a broken Danelectro Cool Cat Transparent Overdrive V2.
Since no actual schematic seems to be available I have tried to create one using Kicad.
Most capacitors are smd, were removed and measured with RLC meter.
The Cool Cat Fuzz V2 input buffer seems similar.
The FET clipping is not yet drawn properly, suggestions welcome.

First time poster here, just wanted to share my findings from tracing the new Orange Amps Vintage Reissue Distortion pedal.
Orange Vintage Reissue Distortion.png
Right off the bat, the actual distortion circuit here is very similar to ye olde Wampler Plexi Drive, but with a few tweaks. The tonestack circuit here is lifted from a Marshall amp (weird, considering this is an Orange Amps design) & there's a pretty neat buffered bypass switching system going on. Interesting to...
First optical compressor I've used and a nice change from DynaComp type I've only previously experienced. Also first attempt at publishing a full circuit trace; hopefully it's right.
Hi Guys,
I have a Cool Cat Fuzz that someone messed with the tone Pot.
I was looking for the schematics to check the original values of the pots on this pedal, but can't find any...
I already looked for gutshots, but seems like there's a variety of different guts...
Supposedly an Si Fuzz Face with a switchable buffer (not a bypass buffer, but a buffer make it not oscillate when using it with a wah), but it looks like there's a LOT more going on in there:
I count 7 transistors :shock:
It looks like there are some diodes and tant caps in there.
Recently got a commission to convert this EQ to 1/4 jacks, new power supply caps and NE5532 upgrade to make it less noisy. I took a bunch of photos to post here for tracing if someone wants to have a go. I have one of these of my own too if I need to check any part values.

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 ??
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...
I haven't seen this one here already, so I gave it a trace both for personal fun and curiosity:
bassmuff.png
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...
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!
Tony
