Attached a pic with comments. I hope that it works out for you.

I'll have a look at the vero tomorrow. Just hold off for a day or two :)

That would be Retroamplis: Link

Hello @gtfields13 I found some purple diffused LEDs in the web shop I usually use. Next time I order something I'll add some. They also have violet diffused LEDs, so I'm hoping purple will really be purple.

Hi all, Arrived late to the party. Built it and it's fantastic! Thanks for sharing CB! The LED is sadly not purple, but violet. It's a bit of a bummer, but I didn't find purple in my local shop. Lots of space :) How does it sound? It sounds great! I don't have many fuzzes, so I can only...

BJT > JFET > MOSFET is what I'd say after a quick interwebs searcheroo.

If you have another medium gain BJT NPN lying around, like a 2N2222 (same pinout as BC184) you could try that instead. Maybe put it in a socket. Edit: Here're some voltage readings from mine if you're interested: link

Sorry, got the numbering wrong in my last reply. Fixed.

Sure it should work in your test box without the switch. If you take the cable you got soldered to Switch 3 (on the right side of the vero!) and connect it to the cable that you got soldered to Switch 2 and then connect the jacks and power the fx should work.

On the vero on the left side, where it says Switch 3, it should read Switch 1. That's the buffer for the bypass. Switch 2 is the output that ends up on the output jack tip. Switch 3 is the effect output. So when you hit the stomp switch you switch between the buffer and the effect. In the...

Hi chork, I had a noisy Sabbra Cadabra until I changed my JFETs to ones with a higher VP. I had some with a VP of ~1.5V for Q2-Q4 in the pedal. I replaced them with some with VP of ~2,1V and that solved the problem. Maybe you have them in sockets and a few more lying around to try this. I think...

I just checked and made a few measurements. It looks like yours, the model is T-7 though. I got it maybe 2 years ago. Never calibrated it I think. Below some measurements against the DMM for comparison. They're not too far away from each other. When in doubt I'd go with what my DMM says...

I have a similar tester. It's not as exact as my DMM. It only gives ballpark numbers. But it's - cheap (20 bucks) - super easy to use - it's pretty fast So usually I prefer it over the DMM for pedal building. When I need precise measurements I switch to my DMM. If you ever buy a DMM, get one...

You're not providing links to schematics, so not sure what you built there. But if it's charge pump whine I suggest to look at the Aion Ember distortion. That was the first DIY pedal where I didn't have the whiny interaction between different charge pump pedals. I think because Aion placed 470nF...

I think you're running into this issue.

In the guitarworld review here they have a low res pic of the PCB. There's the big 1uF cube and on its lower left a resistor that looks like it's reading 1801, which would be 1k8, not 180k. Maybe they had a bad batch where the fab put the wrong resistor in and PedalPCB got one from that batch...

I think I was wrong about Q1. It looks like taking a lower gain transistor alleviates the symptoms, but doesn't fix the problem. After I wrote the above yesterday night, I connected the pedal and played into it for a while. At 9V everything was fine, no noise even at full gain. After a while I...

I built the Sabbath a few weeks back and remember that I used a vero transistor switcher to test a few trannies for Q1, the one in the treble booster. I tried a BC184B, a (2N or PN, can't remember) 2222A and a BC549C. With the gain half way up or so two of them were very noise while 2222A was...

This must be the Chad of the small signal diodes!

Hi, with "under" I mean "going south" of the charge pump, not "underneath". Just to get from upper left to upper right. BTW, I've posted some info at Musikding if you want to take a look: Link
