Coda Effects Black Hole Build Issue
« on: May 04, 2021, 10:57:51 PM »
Hello. I am currently working on a Black Hole build and I am having an issue.

The main part of the pedal works perfectly but the issue I'm having is that the boost section is not working. I have it wired to a 3PDT footswitch as well as an LED. I also turned the 100k boost trimpot into an external pot with a knob. When I hit the footswitch for boost, the LED turns on but all sound cuts out. The other weird thing is that as I turn up the 100k pot the LED will dim.

Any ideas on what I'm doing wrong? Cheers.

Pictures might help. Maybe a link to the build doc as well.

Second this, definitely need pictures to be able to help, also have you emailed Benoit at Coda Effects? He's always been really helpful when I've needed assistance.

Hi. Thank you for the replies. Sorry about not giving proper details. This is my first time posting on the forum. I have included two pictures, the main build doc, and the wiring diagram Benoit gave me for adding a switch and LED for the boost. I emailed Benoit a week or so ago but he must be busy at the moment, which is fine. I figured I would seek some help here in the mean time. I also just wanted to try out the forum thing. If there is any other info or pictures needed please let me know. I have a digital multimeter if any measurements are needed. Thank you so much for the help.

SOLVED. Hi MTK. Thanks for the help. I rewired the switch and got things sorted out over the weekend. The diagram on the left was actually one given to me from Coda but he just drew it up quickly for me so he must not have realized the switch needed to be rotated. All good. Matmosphere was able to catch it and help me out. I appreciate the help though. Thank you everyone for having a look.
