    Now that is cool! He seems like such a cool cat in the vids I've seen of him.

    Noise problems in amps usually come down to a bad tube. You might want to check the tubes by replacing them, one at a time, with known good ones to see if the noise goes away.

    My Sonzera 20 is dead quiet on the clean channel with a the expected increase in noise on the gain channel. I agree with the
    'check the tubes' advice.

    I got my Sonzera yesterday and had exactly the same problem. When I switched it on without any cable attached and volumes at zero the hiss on the clean channel was very prominent. First I thought that this noise is coming from the outside as it was so loud. It is very stable shhhhhhhhhhhh... it is much less on the drive channel. the sound of the amp is really nice and organic but the hiss is absolutely unacceptable. In the same room i have other tube amps being completely quiet ... i assume and hope it was bad luck and inadequate quality control. Returned the amp the same day. Very sad and disappointed as I liked it otherwise.

    cheers Sacapuntas

    I'm glad that I'm not alone regarding this issue and as I mentioned earlier, I had read about the same issue on another forum or review.

    As far as changing the tubes, the amp is brand new and that's unacceptable for $800. I've already shipped it back to Zzounds and just ordered a used PRS Dual Channel C combo from Guitar Center for the same price shipped. I played one a couple years ago and loved it, so we'll see how that goes.

    I have had this same issue on non PRS tube amps. Usually the problem is a bad tube or tubes. One might even be loose or not connected properly. I am with the others - send it back unless the PTC can help you with a simple fix that does not require a technician to do it.

    Again, if I purchased it used that may be a solution but not one I'm willing to deal with on a new piece of year and thus the one caveat for purchasing online versus local.

    Local here in Nashville means an additional 9.25% tax and online doesn't unless it's Amazon.
