here I will give you detailed instructions on building your own
feedback looper. its pretty easy and they are a lot of fun. for guitar players, it works great with a delay in the loop but it can be used with a huge mess of pedals for noise making fun. also works with no input, provided that you have enough gain on the pedals in the loop. for the LED resistor, I used a 4.7K resistor. you can use a 3.3k if you want it brighter. the stomp switch can be a cheaper 2PDT if you prefer. the
feedback pot is 500k Audio or log. the volume is just a 100k Audio/log pot wired like an attenuator with a leg to ground. its worth mentioning that a 500k pot can be added to any pedal for the same effect. please ignore the stereo jacks. just use normal TS jacks if you can.


the schematic is setup to match the gut shot photos

this photo shows the signal path. not shown is the jumper connecting SEND to INPUT to the middle switch lug. all the grounds will be tied together later

all the grounds on the jacks and the 3rd lug on the volume pot get tied together. the power/LED circuit is completely separate from the audio circuits. I used green for the
feedback signal, white for the normal signal.

now you have your own
feedback looper!
