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...
2 different units here. the first one had a blown CA3280 and a substitute ECG VR. The second unit is very distorted. looks like the VR was replaced with an unidentifible device. Schematic and layout to follow.
Dear all,
A friend of mine have a Darkglass Tone Capsule. Actually he send me a photo of the device.
I asked more Photos with more details.
Somebody is interested to help me to tracing this electronic?
Quick search tells me there's nothing on these yet...
Although it's difficult to tell from a yt clip, this actually sounds reasonably like an FZ-1A:
A couple of gutshots have surfaced, and to me looking very Bosstone sans clipping diodes (which you can add yourself) and a couple of free pads for a more bass-friendly response. Seems Jack Orman independently concurs from the youtube comments...
Whatever, it sounds pretty good to me and cheap enough to snag out of curiousity.
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.
Seems there’s been a good bit released but not much talk anymore. For instance the Movall line up is different. I have the absolute zero fuzz and it sounds great. There’s several other pedals in that series that sound good in samples atleast. I bought the chorus based on a video but mine had a high pitched whine. Was a shame because it sounded like a more tweak able Small Clone. I tried their flanger. It ISNT a mistress but it can sound close. There’s a width trimpot on the inside. However the...
I got this pedal in as it was making a lot of noise. The noise was as loud as the effect and made the pedal useless. I traced the noise to a single 470p cap.
I also traced the pedal:

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...
I made some inroads towards tracing the PS-001 Distortion.
Turns out it is more than an MXR Distortion+ with a Muff tone control. Structurally it's more like a Boss DS-1.
(Given the similarity of the Guyatone PS-005 Overdrive to the Boss OD-1 it's not surprising there is some similarity to the Boss DS-1.)
Unfortunately there's some ambiguity regarding the tone control caps. (The two polyester caps on the middle-edge of the PCB where the wires are).
Guyatone made a large number of pedals by there's surprisingly few schematics.
I started off looking at the Guyatone PS-001 Distortion but there's not a lot of PCB pics out there.
In the process I found some info on the sister pedal Guyatone PS-005 Overdrive. At times people have tried to guess what this one is as well
I managed to trace the structure of the circuit. It looks like a Boss OD-1 (ish) circuit with a Muff Tone control. Unfortunately no values.

I promised to put the schematic here already some days ago, but didn´t have enough time. So, here it is... if there is a thread about this pedal, moderators could move the schematic there or something.
If anyone has some good pics of the part values please post them. It would be a big help - thanks!
While I've traced the circuit and I'm confident the circuit topology is correct, there are however many missing values. Some values are uncertain due to poor pics. Others I have outright estimated. That goes for both resistors and caps. I'm pretty sure the electros are correct.
To emphasize the incompleteness of the schematic I've only given it a draft version number of 0.1a.
Here's a link to a dropbox folder with some guts of the Guyatone PS-007 Phaser, including a .svg file with the components values. I hope I did not mess with the color code though...
Guyatone PS-007 Phaser folder
Tracing ain't done, but it may be very close to Boss PH-1, or some other 4-stage FET phaser. The MA522 part is a low battery detection, see the schem I've made for the Guyatone PS-006 Analog Echo...
I've trace the KMD KP-100 Distortion. However, due to limitations in the pics I had there's a few things missing:
- pot values, taper and precise connections are unknown.
- cap values are unknown.
- unfortunately the gain resistor, R8 on the schematic, cannot be read.
- a big one is there's so many possibilities to wire the Bass and Treble controls.
It's an odd circuit. Do not correct it to be a Baxandal! the opamp is wired as
a buffer.
I've taken some inspiration from Manfred's trace of...
