I had a Audere JZ3D installed in my KSD J5 and it seems to have a lower output than the original preamp. Is that normal? I see threads about hissing so I'm aware of that. But I have a Yamaha BB605 w/stock pre and EMGs and it blow this out of the water when it comes to output. All input will help my output. (No pun intended..LOL) Thanks!
