I have the dream rig, HD500 JTV59 DT25, and when it is all working right it can sound great. But way too often lately I seem to be having wierd issue with the DT25. For example, when I turn everything on the DT 25 sounds all "farty" or the whole patch is overdriven in a bassy way. Other times, I will turn it on and the patches from the HD500 won't register properly so I get a combination of all the effects in the HD5oo patch AND all the effects from the top of the DT25 mixed together. What am I doing wrong? Has anyone else had the same issue.
