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...
Figured I’d take a few pics of this before I let it to. Not a bad sounding unit at all. Darker than most pt2399s based delays I’ve used but it has a darker vintage analog delay tone “think dod FX90 or any old Reticon units pushed to their max. Modulation was also nice. Just have too many delays. Only changed I noticed with the chips is a tl072 used instead of a burr brown. Even has voltage regulator and preamp trim.
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...
I have an Blackstar HT Dual pedal Im trying to fix. I purchased from eBay. Shortly after I noticed a problem in the switching. Negotiated a 50% reduction on the basis I would fix. Im not a pro but have built fx and fixed amp problems before so am confident in tackling this.
Wanted some advice before I open the box though.
Symptoms are...
Unit always works in Bypass
Sometimes either green, red (or both) channels are silent.
Sometimes the volume of green or red channel will dip randomly....
Does anyone know what Pro Co has done to the RAT to make it a FATRAT? I'm talking actual circuit and/or component changes not sound/features. If anyone has any gut shots or an actual verified/traced schematic that would be great. I'd like to update my comparative multi RAT schematic (below) to include this new RAT variation so I'm really curious as to what they've done.
Nothing much to see here with all the smd components. But I know others have been curious as well is this is just a crushing orange , bb pre, clone. It doesn’t sound like the bb preamp. Or, atleast the taper on the gain and level react differently. Isn’t near as loud as the crushing orange or bb pre either. All I could make out were the 2 TL072 op amps and 2 diodes d1 and d2. Maybe 1n914 or 4148s? Anyways I figured @cheapedalcollector may enjoy it.
I thought this one sounded decent for a chip
i opened the boost / dist combo box but the smt parts
are impossible for me to see and it was a little harder to
tell where each was
i need glasses but i keep spending money on gear, ha !
I thought the sinle boost pedal sounded better than the combo version
but that may be my imagination as i didn't listen to them at the same time
Been looking at this schematic and wondering why they have biased the opamp this way using the non-inverting configuration. Could someone please explain this for me ?
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?
I don't have an circuit analysis to offer at this juncture, but I've not seen any gut shots of the Kongpressor on the Internet, so I thought I'd supply some. It looks like it might have originally been named Squash Comp in the design phase.
The clustered strips of resistors is unusual looking, to my eye, I haven't seen anything quite like it in the few dozen pedals I've opened up.
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.
I'm half tempted to get a Liverpool just to see what's inside, but if someone has already had a look, I'd be interested to hear it.
Supposedly, some guy on YouTube bypassed the speaker sim so he could use it with his amp - that's what I'm looking for.
I just got this unit in as the owner needed to know if it could run on a 'normal' voltage instead of the 15V 400mA centre positive power adapter.
The unit has a single 12AX7 tube

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...
I continue to trace my Exar pedals - today, it's Exar KM-03 Kamikaze. That particular model seems to be quite popular in Poland back in time because I've seen some good mentions about it. I had two units; both had the same components inside, so I traced the one in a slightly worse condition. For another one, I have a box and user manual.
I was lucky to get Exar OD-1 in good condition for a reasonable price, so I thought I must trace it. Many legends are around that pedal, and pricing on the used market went too far, significantly after JHS added it as one of the modes in Bonsai pedal. I hope my trace will help reduce insane prices on those, sometimes higher than vintage TS ones.
Does anyone know what exactly this does? He doesnt offer it anymore, so I assume it's fair game. I have one lying around that I want to do something with
I traced this one a few months ago and never got around to putting the schematic up here. The only thing that bothers me is how the 9v supply is hooked up to the cathode of the bypass LED. I still have the box but the owner is not willing to desolder the caps to find the values. Any way to measure them in circuit to get a rough idea of what the are? In my experience NP0/C0G caps are usually lighter in color....like a grey and the X7R caps are a darker brown so that's how I marked them on the...
Here is the first draft of the schematic. This is the Japanese version that comes with the orange battery cover. My son in law has the version made in Sri Lanka but, this Japanese one sounds better. I prefer this pedal on my guitars with humbuckers. It does for hummers what a Tube Screamer does for single coils.
