Question Why does my pedal not work when using a 90 degree (angled) cable, but it is fine with a straight cable  Answer Above the mono input on many of our pedals, you will notice the case gets larger. Because some connector shells are quite large, this can cause the plug to not make good contact. If you need to use angled connectors with your pedals, you should consider ones that have a small footprint like the ones from George L. Or, you could just use the stereo in and out to avoid this.
