I've got a problem with my svp-pro pre that maybe someone can help me to diagnose. The problem just started recently. It seems that no matter what I do, the signal that I put into the pre overloads and distorts the sound. It's definitely a problem with the pre. During practice tonight, I plugged my bass into my dbx compressor, turned it all the way up, and plugged the output into the cabs. Of course, it sounded a little flat, but it was good enough to get through a rehearsal. Any thought on what the problem might be? It seems that no matter how low I turn my bass it still overloads the pre.
