Bryan Daste Wheresthedug the issue goes away if I swap the guitar cable with a wireless transmitter. The issue seems to stem from the guitar, but it doesn't. I've tested with many guitars, and they all gives this amp-buzz in the background when I am using guitar cable. I've tried 4 different guitar cables and they all yield the same. Also four/five different guitars with Humbuckers, SC, Suhr pickups, asatobuckers etc. (Yes, hum goes away if I turn down the volume on guitar!!)
It's not ground-loop either, as you say. Some guitar tech from Peach suggested that the wireless transmitter worked as a buffer, effectively nulling out the buzz, and something to do with impedance when I am using cable instead. I'm no electrician, so I don't know what this mean, so I need to try and ask stupid questions here in hopes of figuring this thing out, as I'm sure I'm overlooking something mandatory, or even better/worse, it's supposed to be like this, perhaps? Maybe I'm nitpicking?
Either way - if it's supposed to be like that - I'm probably nitpicking, but if I am able to completely remove it with wireless transmitter, I really want to do it with cable aswell, for recording purposes. So I don't have to rely on iZotope RX software and remove hum afterwards..
My dealer-shop where I bought it, here in norway, they tested it and concluded the unit to be fine. They said however that there is a slight very low volume hum, but that it's normal.. This is what led me to believe I'm nitpicking. But If I am able to remove it with wireless transmitter, there's gotta be a way for cable too!
