I have used tube amps for years most of which were high gain amps. Marshall, Mesa, Fender, Peavey to name a few. Currently I am playing through Jet City amps. I wanted a Soldano but didn't have the funds so I went with Jet City. I have jca 50h and just bought the 100hdm. Love these amps and the price was great. My only issue is the amp noise I am getting. Louder than the normal hiss or hum although my old marshalls were pretty noisy. Now I went through my signal chain and added a noise suppressor which helped but when not playing there is still noise. My 50h is about a year old but the 100hdm I have only had for about a week. So is there a better way to cut the noise down than just a noise suppressor. I mean both amps are pretty new so the tubes shouldn't be bad. Anyone have either of these amps and had the same problem? If so how did you fix it?
