I have been racking my brain!!! I have a Crate Vintage Club 6210 and it has a parallel effects loop with a mix level on it. I have the HD500 and it sounds out of phase in the loop. I also have a B52 AT100 and a Marshall VS 8100 and the HD500 sounds great in those loops. I have tried tweaking the amp and HD500 and I either lose the effects level or get that "processed" out of phase sound. I have read that parallel loops and digital effects don't play well together. Are there any pedals to fix that? Anything I can do to the amp to fix it?
The amp sounds great and am using the HD500 just for effects. Really frustrating. Any help would be great.
