Hi,
it is such a shame that a lot of the pictures of this thread are lost. They are very helpfull for anyone o wants to give the 1590LB a go.
So, to start I want to thank you guys and specially Cozybuilder (thanks for sharing the layout of the zombie chorus) for sharing some gut shots.
I started from the ultraflanger, which has some similarities with the zombie chorus (one opamp for the signal, one BBD, Opamp LFO...) and decided to go with the electric mistress signal path to cut some extra noise.
I used the V3207 as the BBD and based much my schematic on the design presented here:
https://www.diystompboxes.com/smfforum/index.php?topic=91981.0To make it fit the 1590LB there was some sanding involved...
I had to sand the base of the screws to fit the pots. Another critical area were the jacks. They were much larger than they needed to be, so I sanded them a little bit. From the round shape to a more ellipsoidal shape. Here you have the final result:
Here you can see the etch. I used a rock poster for the front and back of the pedal. Since I don't sell my builds, hope there is no problem in that.



Here a special look at the positioning of the parts. Critical part is finding space for the jacks, so that they are not as deep/high. The potentiometers go side by side, with the center pots turned to the side wall in a slight angle, where the 9v jack fits perfectly.

The board is as large as the area available, so low profile components is a must. I had to solder some components on the copper side to spare some space.


I soldered the pots to one side, so that the board can go down as a lid, with the connection to the pots working as the hinge.




I'm also working on a standard ultraflanger using the v3207, but it is way noisier than my build with the MN3007. It could be the layout, since it will also fit in a 1590LB. If you have some suggestions, it would help me box it faster.
Cheers
Thomas
