HH, I had the Overdrive line driver, and it gave me noise and crackling problems. Can your amps handle the extra input? Mine might have been defective though. Not really sure. I emailed tech support and never got a response. I emailed them again to tell them so and that the problems were eleminated upon taking the unit out. Then they replied by saying that if I want to put it back in, they can help me. <A little late there>. Just don't want you to have to go through the same trouble that I did.
