I own a Digitech BP200 and when I run it into the effects loop it becomes noticably distorted. This happens on both my Carvin R1000 and my Fender Bassman. But when I run my bass to the BP200 and then to the amp it is better. Is this an issue with Digitech equipment. Someone told me somthing about low output or somthing like thatwith digitech. They said this could be the problem. Anybody notice similar problems or other effect units that don't get along well with effect loop inputs?
