I spoke with someone from EHX about a possible repair. My main concern is that they will be using new parts if a repair is needed. I don’t want my sound to change. I think the older q-trons sound better than the new models and are closer to the mutron sound as well. He said it could possibly change the sound. Has anyone had repair done, does it change the sound? Does it make it sound like the new models? Any other options to keep this thing original? I don’t want it to end up being a newer sounding q-tron in an old body. Thanks
