Petyr of The Dying Tree has recently posted an interesting Instructable on how to create a feedback return box for use with delay pedals. The feedback option works by sending small amounts of signal from the Delay Output back into the Input of the pedal. The signal amount for feedback is controlled by a 10K Logarithmic potentiometer connected to the ground in order to properly adjust the volume. This simple hack also makes it is possible to create sound on sound loops with delay pedals that have larger sample times. The obvious gotcha is the degradation of sound quality with each repeat. Enjoy.
Here is a sample of what the feedback sounds like.

[...] GetLoFi points out this interesting instructable – build a feedback add-on for use with cheap digital delay effects pedals. Enter the “Apocatastasis” – Most expensive analog delay pedals have a feedback knob that lets you drive the output of the delay effect back into the input. My Ibanez DL5 Digital Delay did not have this feature, so I decided to make one and make it cheap.Sure to be handy for achieving that retro-cinema ‘sting’ of despair – and countless other sonic atmospheres of the echoey-bizarre variety. – Apocatastasis (feedback return for cheap digital delays) [...]
hola me podrian explicar como hacer bn este aparato q ami no me funciona…
porfa ayuda… es urgente
me podrian desir q de cuanro es el capasitor q ocuparon..es de 0.5 uf
pero q voltaje
la mayoria de los pedales se alimentan con 9 volt este como no dice en ningun lado?
cuál es la fuente…??
Hey That Delay pedal doesnt works, it only works as a volume pedal, and put more information as the voltage of the capacitor, and why does it doesnt works
I hope you answer soon
Thanks
another question
the capacitor is polarized or not, and what are those Fx in and Fx out, were do i connect them??
