Listen...



Here's the riff i am playing in the two videos above, and a song from our June 24th setlist:


My neighbors 5 houses away could hear this yesterday. The video doesnt really give yiu a true indication of the volume level.

Oh I will completely agree on Marshall hum. It's a very real thing, especially once you begin to use some internal gain but becomes unwieldy when you use external gain and overdrive. A Noisegate becomes almost a prerequisite for those amps once they're pushed.

An internal Noisegate would be a cool feature to see in the future but I don't know how well that would be received

Note the Line 6 has a built-in noise gate and it really works.
 
None of my Marshall amps are noisy or hiss I still have six of them 1968 Super Tremolo 100, 1969 Super Lead 100 red, 1969 Super Lead 100,
white, 1969 Marshall Park 75 ,1970 Super Lead 100, 1971 Super Lead 100 white.
a poor ground to the filter supply will cause hiss ran into that with the Trainwreck Express amps used AWG16 pure silver wire for grounds solved
issue with PCB amps is capacitance on the traces you can only do so much with that cheap to mass produce.

Yep…last year, finally found a reference for the ground in my Laney that could be improved upon. I rerouted it to a more efficient location, and it’s night and day different. Clean.::you can’t even tell it’s powered up. Dirty…barely any hiss or hum to be had…love it now! It’s no boutique beauty, but it’s a solid player. Best big clean amp I own…and it’ll melt faces when you wind it up…shake your guts kinda thing…now it hits you by surprise, with the quiet approach.

I'm not talking about noise from a poor ground, but normal operational noise. Even the best Marstran transformers still generate some degree of noise.

I've played more vintage Marshalls than i can name, and numerous boutique amps owned ny wealthy/eccentric colleagues and all hiss to some degree, when running, especially with extremely high gain levels.

I'd like to invite @syscokid and @ivan H to chime in on this...

The noise I believe we're discussing here isn't so much a grounding issue, as on all 3 Marshalls I have, it is non-existent on clean channels or at lower gain crunch settings. The sound would be best described as a hum and it usually kicks in when either they are on high gain channels with the gain pushed up high or introducing an overdrive or even a distortion into the front of the amplifiers on the same channels at lower gain settings.

Basically, it's too much gain going on and thus a noise gate comes into the mix. On non-master volume amps such as the ones you listed? This is an extremely uncommon occurrence

Now, I did have some issues a while back when the power company was working on our utility lines coming TO our house for a couple of weeks and was getting wrecked with crazy interferences. Simply using some clamp on ferrite magnets on the power cables cleaned that up entirely until they were finished. I took them off afterwards and the interference was gone entirely
 
Well Mike the amps I have been using for the last 15 years are channel switching high gain overdrive channel with master volume
some of the venues our band plays the electrical is dirty turn of the century buildings I use a Furmann power conditioner
on my Friedman efx board has a high quality power supply not a wall wort
end of the day what ever works for you. I'm a student in this life not a know it all.

We are all students indeed, good sir.

The power conditioner is critical, as you have pointed out.

Im also playing with throwaway gear, because my main focus had to be supporting my family, so I've never had really good gear like a lot of you guys have.

When I'm asked to fill in for these projects, i generally have to just use what i have laying around...
