When I record or play live via my sansamp PBDDI, it sounds great. Latley however, I've noticed that my overdirves, wah's and other effects don't seem to come through the house speakers, or into the recording mixer. My signal chain is bass>effects>Sansamp>amp. Everything comes through great from the 1/4" out jack that goes into my amp, it seems to be just the D.I. feature that is taking all the effects out. Even full-on distortion sounds extremly weak. Anything that I am missing? I don't thnk I have the XLR pad on, so I don't think that's the problem. Thanks for any help.
