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.
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.
Same here. Brand new 20 hiss was unacceptable. Clean channel, volume at zero, nothing plugged in. Dramatically worse with a pedal (BB Preamp). Very unfortunate. This amp I want. Sorta takes me back to my Blackface Bassman in high school.
Considering getting again but I'd hate to return another. Seller should not absorb that, PRS hopefully does. I've seen enough complaints to make it something to be addressed. By now I am expecting PRS is. Manufacturing issue? Shipping? Maybe the tubes loosen, etc.?
I did end up sending mine back and picked up a mint PRS Dual Channel C for the same price so it ended up working out well for me. It's a shame that "some" of the new amps are shipping that way (which is what I assume) since I could never play one locally to see if it was an anomaly or not.
I picked up one of the 20W Sonzeras when they first hit the stores...and the tubes were shot. Nasty hiss and pops, regardless of what was or wasn't plugged up.
I took it back and got another, and haven't had a single problem with it. All in all, I'm thrilled with mine.
That hiss noise was awful, though. Almost put me off of them, altogether. I'm glad I gave them another shot.
