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..
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...
HI,
I'm new. I have problems with the Ibanez AD 190 Time Machine.
I was given one but it doesn't work and I'm desperately looking for a schematic that I can't find. The machine turns on but doesn't make any sound, furthermore two jacks have probably been replaced and I have no idea how the originals fared as these are completely different.
I thank you in advance.
Diego.
I've traced this little clip-on piezo preamplifier for fun. Seems like a simple yet nice design (aside from those ridiculous electrolytic coupling capacitors a bit everywhere and the wimpy decoupling, which should be fine for battery power). I haven't seen many acoustic guitar preamp schematics around, hope this gives a nice starting point to diy builders.

Basically 10M JFET input buffer into inverting amplifier into active baxandall.
This is obviously based on the Single Channel Carl Martin Plexitone.
I really like the sound of this pedal. It's got that Bright-Channel Plexi character and a lot of gain.
If you're after a pedal that will help you get an EVH brown sound, you could do a lot worse than trying this one.
At less than £20 new, you can't go wrong.
I can't find a schematic of the Single Channel Plexitone - I wonder how close the Plexi-m is to it.
It would be interesting to see a schematic of the CM Panama to compare...
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?
Found this gut shot online. I believe this is the first version red one. I just purchased the 3rd version for 50 and certainly not bad for the money. However I opened mine up and the guys weren’t exposed. Didn’t feel like taking it apart. Wonder what’s hiding under that goo.
I miss the company. I’ve just purchased this thing and really have no idea how to use it lol. Seems like the left foot switch is going bad as well. Remember having his blender and comp and like both of those. A good bit of flux in there.
Hi! I've picked this one up used, and it's an older, not status LED model. Sounds decent, and a good range of speeds available. Anyone saw a schematic for it, or should we try and trace?
If so, I have them. The pedal is supposed to be a clone of the Free The Tone's String Slinger.
I'd love to see the schematic of this pedal but I don't have the skill to decipher it. Sounds like it's based on a Tube Screamer with less of a mid focus.
This is not meant for tracing, 'cause the circuit is just a TS9 clone.

It's just to see which components are used. The V810 is praised by some folks for having its own tone. This is a model that may have more than 10 years, kinda old school, and it sounded good indeed. A friend of mine purchased a brand new one a month ago but said that it sounded far worst than the model in the photo (that was property of another common friend...), I haven't checked...
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.
I’ve been searching for months for a simple gutshot or schematic for this Fet fuzz and all I’ve found is attached below. A crappy pic I found on a Japanese site. I can buy the pedal but it’s not exactly dirt cheap.
If anyone has the schematic, please post it. Thanks.

Description from Guyatone:
When Guyatone first set out to create the ultimate fuzz pedal, they looked to the past for inspiration. Thus, the Fuzz 2000's circuit design was based on the most famous...
The original thread for this was for the first version which was different and the schematic pics are long gone.
I got around to tracing it myself, it's slightly different than a phase 90, just some different part values and an extra resistor on the output. Enjoy.
So a friend wants me to modify his TS9B. He bought it thinking it might be similar to the Voodoo Labs Sparkle Drive, but at first glance it looks quite different than any other TS I've seen. None of the usual suspects appear to be present like the pair of 220nF tantal caps for the tone circuit. Prior to tracing, I'd say that it is a Baxandall-type or similar.
The bottom line is that we both assumed that the TS9B was just a TS9 voiced for bass with a blend knob, and not something rather...
Hi, got a pressure tank, took it apart and got some pics :3. It's actually very close to the diamond comp minus the tone bypass, even down to the double coupling caps which is kinda pointless in this mlcc version but still cute. Our unit's frequency response is not very flat, especially at higher comp settings, which is no surprise with the LM358 (0.6uV/s slew) that works as the makeup gain amplifier (U1) in this unit. We swapped it for a TL072, and while the bandwidth still feels limited at...
Hello,
As I am an avid cloner myself, I thought that it's my time to give something to the DIY community. I got ahold of the effect mentioned in the title and I am providing some gut shots, also a list with components. Capacitor values on the list have ? due to my lack of experience with SMD components. Where there is no indication on the list will be completed tomorrow then I'll get a magnifying glass. All other info from the list are markings on the components (mostly SMD).
Here are some...
below some line6 M9 gutshots. I need to opened it to replace a bad LCD and took some pictures.
The M9 schematic is attached as well.
Maybe it help somebody.
Hi all,
I own since ages this Dunlop CBM95 Mini Crybaby, which I love it as it is super compact and space friendly.
Lately I opened it to apply few mods (beside the 3DPT switch with bypass status LED which I already did years ago).
I didn't really trace the circuit, but from the components and values I saw, I think the schematic is the same one as the Crybaby CB95 with the input buffer and MPSA18 transistor.
In general I wasn't able to have a reading of the capacitors (beside the 220nF and...
Hello FreeStompers. I recently unearthed a file folder of Clockworks documentation and am pleased to be able to publish the info here for your entertainment. From the file notes it looks like I had the original concept idea in 1977, but didn't get around to actually building anything until late 1980. My first attempt apparently involved non-retriggerable one-shots but that was less than satisfactory and was abandoned in favor of the analog frequency divider approach that ultimately went into...
It is a good sounding mild overdrive to push a tube amp.

Here's more informations about this little cheap, simple but really good sounding pedal : the MUFF Overdrive EH Nano.
I traced the schematic from the double-sided PCB. There is no SMD components in the unit (2011) :
This is the direct descendant of the 1969 MUFF-FUZZ, with the exception of C5 and C6, which were 0µ1 at that time, and of course the RF filters, which didn't existed. The MUFF Overdrive sounds even more mellow for these reasons.
So, a couple of years ago I was watching videos and came across the Russian Spektr-3 Fuzz, Wah, Autowah unit and thought the fuzz part sounded pretty good.
Some time later I saw some demos on YouTube of just the Fuzz section that Soviet Guitar Effects has made and sells for the mere lowly pittance of AU$572.80¢…so I decided to get the schematic, manual, and extract the circuit myself and, naturally, give it away for free on FSB. :D
I haven’t made one yet as I’m waiting on some parts from...
