I bought this new off a guy from ECA forum and have had it about 4 months. I installed it the other day and I guess it's just a piece of $hit out of the box. Brand new and the gain control does not work. The box was not damaged at all during shipping and I never dropped it, doesn't have a scratch on it but turning the gain control has no effect. Guess I'll have to send it off for repair but what a bummer and $hit for QC
