I think you have the wrong value in r21 at least. Looks like a 470r not a 47r. Probably doesn’t matter but may be worth checking others

Sounds good. If you can find where the sound stops that is a huge clue.

You should get the voltages in the link below. Yours seem ok except for pin 8 https://www.madbeanpedals.com/projects/_folders/DistBoostOD/pdf/SlowLoris2020.pdf

It wound be good practice to build an audio probe. If you go I bet the sound stops at pin 3 of the op amp.

I think you can also use a tl071 and an op07.

Did you say that you used a tl072? Those will not work in this. If so I think that is your problem. Try a lm308 as suggested

Thanks. I’ll get some of these!

Hey everyone I need more envelope filters in my life so I thought I might make an EHX Q-Tron. I found the schematic below, but here they simply list "opto" as the vactrols/optocouplers. https://www.freestompboxes.org/viewtopic.php?t=6849 I was wondering if anyone kew what would be a good...

Hey. I have not made the change you suggested in the CE-1 but I have in pretty much every other chorus that I have made. I love putting this capacitor on a swtich to get low, medium and high depths.

I just checked the layout and it seems set up for 2n5088. Are you sure the pinouts are different? They seem the same according to my google search. Try the transistors as normal without swapping b and c.

Thanks. This is really helpful. I’ll try this out

Hey everyone. I bought some of these led bezels lined below to try out but I’m having trouble getting them to work right. https://www.taydaelectronics.com/5mm-bezel-led-panel-mounting-clip.html Either they are too loose and the LEDs wiggle around or they are just too tight and I damage the...

Pics?

And another video with an envelope filter in front. I really like this sound.

Here is a video of my semi successful attempt. I managed to get it going by breaking the connection between the gain knob and c13 and adding a mosfet boost here. I think for next time I will make the following changes: Use the spare op amp for extra gain stage between gain and c13 Use a 1m...

Yes I’m realising that now. I didn’t realise the Timmy was low gain. I tried to do some calculations but I was obviously off. Do you mean I should increase the amount of boost in the first stage or f the Timmy? I’m not sure how boosting the second would affect the wave folder? Sorry if a silly...

Hello everyone. Some mixed success on this project. I put it together on the weekend and the Timmy section works. However the wave folder only works if I I have large amounts of signal going into it. I have placed a Mutron 3 in front of my prunes and Timmy and this activates the wave folder...

Typo sorry. Fixed it

The three things you have highlighted are all the same op amp. The + and - represent pins (Edit 8 and 4). Not sure about Kikad but in easy eda I select a footprint that has these three parts under the same heading. To make just one footprints out of 3 parts they must be named the same thing...

Thanks that looks good. I’ll save that.
