    Ampeg B500DR preamp issues?

    I have a Ampeg SVT410HE the B500DR, I have an Ibanez SR505EL (Bartolini P/u’s, passive with active EQ) I hooked up this goddamn lexicon pre and I guess I plugged something in wrong to the out....well now the damn thing won’t do anything other than hum noise. Anyone have any ideas?
