Re: DMB Stellar Drive [traced]

Do someone know something about the four knobs version? It has a Clean control, a sort of blend.

Re: TC Electronics - Dark Matter [schematic]

Thanks for sharing it, UncappedOptics.

I guess the Bass pot is reversed.

Re: Seymour Duncan - 805 overdrive

The schematic is in the doc, now:
https://www.pedalpcb.com/docs/SeyfoamOD.pdf.

I tried to draw a layout.
NOT VERIFIED

Warning: Two cut track even under the transparent 18nF.

Tell me if you see something wrong.
(Probably I can't build it soon.)

Re: JHS - AT (Andy Timmons) Signature Drive [traced]

Hello. I started from a Crunch Box veroboard layout to convert it in the JHS AT version. Almost the same thing, I just used an external pot fot trimmer to have the Air pot and a 100nF in the power supply. ANd I added 1k resistor before the lug 1 of the Gain pot. The EQ pot is a reverse log, followin...

Great update! I got one odd thing. I have a 1 next the Private Message button, but I have no new message. My last one was in April. I means that there is a message that (technically) hasn't been read yet... it should show in RED. There is another bug in the message system: when selecting multiple m...

Re: Orange Micro Terror

Yes, I didn't analyze the schematic with much careful. I need to look that well. Indeed, it was strange even if I didn't thought about it. :) Tha guy who drawn the schematic said that is tracked from the original amp, but of course he admits some mistake can be there. It's suspect the Tone section. ...

Re: Orange Micro Terror

This schematic https://gitlab.com/jofirel/uterror-amp/-/blob/master/uterror.pdf has indeed some important difference schematically speaking and a lot of difference in the frequencies. I don't know about the sound. In my emulator software the first version of schematic here with flat settings appears...

Re: Orange Micro Terror

Thank you. It seems exactly what I was looking for. :D I noticed just some difference with the other schematic above. A 1M resistor in the Vbias after the input cap and resistor. And the cap between the lug 1 to the ground is 100nF instead 22nF. The voltage is 12, in the first schematic is 15v. It d...

Re: Orange Micro Terror

Thanks for all your answer camljenkins94! :wink: The thing I would like to do is to replace the tube stage with an easier (for me) JFET stage, but I'm not sure how I can convert this tube stage exactly using the JFET. I could use a simple JFET stage Fetzer Valve style, or echoplex or something like ...

Re: Orange Micro Terror

Hello, I have four questions: 1) The stupider one: the schematic above and the parts value are just assumed or those are accurated? 2) The zealous one: where to place the JRC4558 and where the 4560 (I see it in the picture)? Maybe the 4560 is a low noise version, so it could be better used in the ga...

Re: Keeley - Fuzz Bender [traced]

I went ahead and built one. Sounds pretty close to the demos I've heard online. Used TL072s for the gyrators cuz my bench is a disorganized mess and couldn't find my 4558 stash (or I'm just out). Germanium is a Russian MP38a at around 100 hfe. For Q1-2 I tried both 2N5088s and 2N5550s. Both worked ...

Re: Keeley - Fuzz Bender [traced]

NPN Germanium is such a crapshoot. I'd probably just use low gain Si and stick a little snubber capacitor on it. No one can tell the difference. https://youtu.be/SzIQsdn7dl8?t=400 Keeley talks about the pedal. The transistor is around a low gain, 100 hfe, I think he meant it. He says this particula...

Re: Keeley - Fuzz Bender [traced]

The datasheet of the 2SD352 https://pdf1.alldatasheet.com/datasheet-pdf/view/108724/ETC/2SD352.html I see he's bought some of those 2SD352B off ebay. I tried some, they were really leaky though. Good to see he's made them work. Is the B in the 2SD352 B just a conjecture? In case I think it should be...

I'd use a 2N222A, too. But I can't find GT404B. Some advice for the germanium transistor? And the HFE?

Re: Wampler Pedals - Triple Wreck [traced]

I find too much muddy the Vintage Mode. (In the last production the name is hard, I guess.)
Of course the 4.7nF to the ground cut the high, but when I engage that mode I have to increase the Treble. A bit odd.
