Jake, I worked with you via the support ticket system. Checking the headphone output ensures the problem is not down stream from the pre-amplifier.

We actually just received your unit, about 5 minutes ago, and gave the driver some grief. We were here all day yesterday, I was actually here after hours in addition, and FedEx never showed. Feel free to check your tracking again, you'll see FedEx never made it to our location yesterday and the item was never scanned outside of the FedEx facility in Seekonk (until today). In the future, feel free to contact us directly.
