Echolocator delay fully cranked for guitar-style feedback (no talk)

video upload by Richard DeHove

"I've always loved dirty guitar feedback. But since I don't play guitar (other than very bad Punk bass) it's proved hard to replicate with synths. Lately I've been looking at the Audrey II feedback drone thing which is all about feedback. At around 400 Eurobucks that seems a lot to pay for feedback so I thought: surely there's something that I already have that can do controlled feedback?

Delays are a reasonably obvious choice although very few have enough controls to generate the classic feedback tone yet also keep it under control. Happily the Echolocator can by a little manipulation of its compressor setting. At zero (in the 0 to 100 range) it is just a little too keen and can generate an overload which freezes the unit and requires a power cycle. I finally settled at "9" which gives it just enough compression to prevent meltdowns. Even so the output level needs to be kept low. Most of the other parameters just add degrees of thickening or turbulence which you can see in the video.

The routing here is the DB-01 into the Echolocator and then stereo out to the Zen with generous serves of distortion and a touch of lowpass filtering to roll off some of the shrill top end. I had thought the Echolocator would be the Zen's executioner, instead they're now a loving couple.

In the two demos here the first is with the clean delay setting with the feedback amount set low in the patch. The second demo using patch 54 uses the 'dirty' delay setting and has the feedback amount programmed high in the patch which is why it starts whining as soon as I switch to it.

0:00 Demo 1 clean
2:07 No Zen
2:51 Demo 2 dirty
3:50 No modulation
4:20 Timing change
5:00 Thick modulation
