I made this permanent breadboard version of the abovementioned and housed it just now. Because I kept the components and pots facing upwards, the gut shot is not particularly interesting, as you see:
I made a little mod by wiring an LED to show what it does when you change the waveform, delay, echo duration, number of repeats, and so on. It runs off a single 9V power supply at the back, very convenient for us pedal builders, I think.
It's housed in a matte dark grey 125B landscape enclosure from our friends in Thailand. The green switch initiates a one-off event at will or you can trigger it with a gate signal (sockets at the back). I'll use it to trigger complex sampled percussion events and other general mayhem.
Thanks for reading as ever and wishing you every success with your forthcoming builds.
Here’s a pic of the original layout. I’m pretty sure there are simpler ways of doing this but it worked for me.
One thing to be aware of: I had to insulate the original metal jacks from the enclosure after housing it. Seems like this circuit doesn’t want to be grounded metal to metal. Simple solution is to use insulated jacks (IOW, plastic or anything where the jack ground isn’t connected by default). Or house it in a plastic box if you prefer.
You may also prefer installing the pots on the other side of the board. Normally, one sees the components facing up as you look into the box from the underside. Maybe easier to troubleshoot if you run into problems later.
Let us know how you get on and best wishes for your build.
