https://diode.zone/videos/watch/1c85b9da-c963-4d09-9ffd-4837a8f834bb I opened up my Radio Shack "Electronic Reverb Control" delay unit and replaced jumper JP3 (which is in series with the original "delay" fader) with a 1MΩ variable potentiometer, as well as a 100kΩ pot instead of R21, which is the feedback resistor for the delay circuit opamp. In the video I am running my Korg MS-10's output into the (noisy, but beefy) unit's microphone input and play a few notes. The larger knob at the top is the extended delay time, and the smaller knob underneath affects the feedback. I captured the output with my soundcard, but applied no processing to the audio. For reference, I used the following tutorials as inspiration: https://forum.ableton.com/viewtopic.php?p=426956&sid=8d60bdcdd0f2933aa8a5ce3da7650b8f#p426956 and http://clacktronics.co.uk/2011/realistic-reverb-noismaking-mods.html Tue, 20 Oct 2026 15:48:13 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://diode.zone https://diode.zone/lazy-static/avatars/61b689b7-84d5-43c7-9fa8-e63a7fd1d952.png https://diode.zone/videos/watch/1c85b9da-c963-4d09-9ffd-4837a8f834bb All rights reserved, unless otherwise specified in the terms specified at https://diode.zone/about and potential licenses granted by each content's rightholder.
