Hi all, I got a Genz Benz shuttle about 2 weeks ago and after a few minutes or so it'll make a certain sound that I don't think is normal. It sounds a little like the static sound from older TVs when a channel is not available. I've uploaded a 10 second clip to this post of the sound. The noise comes and goes as it pleases. It'll happen with whether or not there is anything in the input jack. I've tried two different cabs and two different Speakon cables (one I just got the other day), so I'm about 100% sure it's the head. Any thoughts on what it might be? I'd feel weird to pay as much as I did for it if this is normal. I bought it new online from an authorized dealer so I'll get with them first and see what to do, but I'd like to know what actually is wrong first. I'm an amateur bassist and am not very familiar with the electronics portion. Thanks!
