Causality MKII Phaser

All info for this project is here: https://www.diystompboxes.com/smfforum/ ... ic=80456.0

It's a well known circuit in the DIY circle as you can make it with easily obtainable parts that don't require matching or tracking down obsolete parts.

I built this in an old Marshall footswitch enclosure. It's the only box I have that's big enough for the PCB... which is my fault, it could be downsized by about 40% but it fits well in this box and since I didn't need the footswitch it made sense.

Speaking of PCBs. I have 4 left if anyone wants one, and the corresponding 3PDT switch PCB if you want that. They look like this:

Part values are all on there except the ICs. IC1 is a LM13700, the others are a quad opamp and a dual opamp. D3 is the on/off LED and the CLR sets the LED brightness.

It's a good little pedal. Has a huge variety of sounds if you're into phasing. It does the raygun thing and the soft swell thing well enough and was worth the experiment.
