Tesseract Reverb

loe
Missed out on the group buy for these PCB's. It would be great if someone had time to do a vero layout for it.

All of Chris' build docs (including the Tesseract) are here (schematics included):

Definitely not an easy project, I hope I marked everything needed. I found out after finishing the board that the "chaos control" should be a trimmer, but I don't currently have the clarity to continue editing. Any pair of eyes for crosschecking are more than welcome

***Updated-again***

Alright, looks good :).

I had a look and found some things though:

The 1uf on IC1 pin 1 and 2 should have its positive side connected to both these pins, and its negative side to Tails 2. Currently it's connected positive side to pin 1 and negative to pin 2 and Tails 2.

Note that Tone 3 connects to BTDR 5

R21 (connected to the 100nf on Feedback 2) is currently 20k but should be 15k

BTDR 3 is mentioned twice. The one on the right is BTDR 1 I think.

Updated-again, I think description and all connections are now mentioned.
Now let's see if anyone will give it a go :)

I built this, but it did not work. Neither did the clean signal work. Has anyone checked the layout yet? Thank you for your work.

I am newbie building layouts, but I think the resistor between pin 6 and 7 of IC1 is 10k instead of 33k and the resistor in the bottom row is 22k instead of 1k. But that's probably not what keeps it from working. This caught on a quick comparison between the schematic and the layout.

IC1 Pin 6 is currently grounded.  Needs a cut anywhere between the 4n7 and 100n caps

I did the cut suggested by Ciaran and now I have some sound, but quite distorted and uncontrolled. Tails footswitch is not working and apparently only the delay works and not the Reverb

With few adjustments, you can mark as verified. Lacking a cut in the top row between the two resistors and the cut mentioned by Ciaran. The Resistor in the bottom row is 22k instead of 1k and the 33k resistor on pin 7 of IC1 is 10k. I fried my first Belton, but after those adjustments and the Belton trade, it worked beautifully. Maybe it's my favorite Reverb.

I´ve watching the only video I found, and this is great. What is that, a gain control for the reverb? With that feature and the predelay this is definitely a step above from other projects.
Does this colour the original tone or is transparent?
Cheers.

I built a little modified version a few times.
