kyfast Posted July 17, 2019 Share Posted July 17, 2019 The foot switch on my Fuchs Fullhouse 50 has a trs cable, and has LED's on it. Will the Helix still control the channel switching, or are there voltages from the amp that will damage anything? Something is powering the LEDS, and I don't want to hurt the amp or the Helix.

rvroberts Posted July 17, 2019 Share Posted July 17, 2019 seems you left out what actual map you have - makes looking at your question difficult. Quote Link to comment Share on other sites More sharing options...
patdixon Posted July 18, 2019 Share Posted July 18, 2019 I posted this same question when I first started, both here & on the Blackstar forum. It didn't hurt my LT at all & works very well. Got some noise but fixed that with a hum eliminator. Hope it works as well for you. Quote Link to comment Share on other sites More sharing options...
patdixon Posted July 18, 2019 Share Posted July 18, 2019 BTW, Richie Castellano does a great vid where he shows how to overcome the LED switching reversed if that happens to you. I've got a link to it in one of my earlier posts. Quote Link to comment Share on other sites More sharing options...
kyfast Posted July 18, 2019 Author Share Posted July 18, 2019 I fixed my original post. I guess my question is, if there is some voltage coming from the amp to power the LED's on the footswitch, will it harm my helix ext amp port? Quote Link to comment Share on other sites More sharing options...
patdixon Posted July 19, 2019 Share Posted July 19, 2019 Yes there is and no (at least in my case) it won't. Quote Link to comment Share on other sites More sharing options...
