I haven't run it flat out yet but at reasonable volumes there isn't any buzz. I have not fronted it with any pedals yet. I picked it up during some down time so it's just been used in my den so far.
Hey Wattage, does your ac15 buzz at high volumes. My new one is. Even at quieter volumes it buzzes very loudly when I use my overdrive pedal. I'm just concerned if that's the amp or the pedal.
It is a cathode biased amp. Those mofos buzz. You can get lower noise tubes, but part of the sonic character and richness of cathode biased amps comes with the price of a bit of hiss. Call it the "rock and roll" tax. You won't hear it once the drummer starts up and the band is rocking.
To use it and get the sounds I want at full volume meant I had to do some mods and mostly I just didn't feel like doing them. I knew going in that might be an issue but I gave it a shot. I imagine I could've worked with it if I really wanted to.
The reverb was kind of lame, a reasonably simple fix with a new tank. The Greenback was not the right speaker for me in this amp, it's a shame I've liked it in so many other situations. Opening up the amp it had a nice roar but I could never really get the tonal balance I was looking for, I assume it was part speaker, part tubes. There were a lot of really good lower volume sounds that I didn't find translated well once I opened it up.
Not a big deal, still like AC's a lot but I'll hold off for now.
***in dull disclosure mode*** I did happen to get my old Crate VC2112R back full time so the Vox would kind of be sitting around waiting for attention
