Weapons of choice for this nights frivolities

Just got the 350 combo for Jazz rehearsals and home practice. What a powerful and good sounding setup.

I do have a small issue with the fan. Reading this thread lead me to believe the fan of the MG350 was ultra quiet and thus suitable for bedroom practice. With my unit, the fan comes on immediately, even without playing a note, and it sounds about as loud as my desktop computer. Absolutely no problem for rehearsals, but definitely noticeable when practicing quietly at home without backing tracks. Mind you, it doesn't sound broken, I am just surprised it would be louder than my other class D amps.

I would like to ask the other owners of the MG350 if their amp shows the same behaviour.

Let Jeff chime in, I don’t think I’ve ever heard my fan

My 800 is virtually silent...
Mine is also pretty quiet, but it’s definitely audible when not playing (in a quiet environment). I think that the different experiences being shared are due to slight variations in fans, playing environments, and people’s hearing.

I personally wish that the fan would only run when actually necessary due to heat. For example, when practicing with headphones in a cool room it shouldn’t be running.

I’ve also noticed that the surface it sits on makes a difference. On a wooden desktop it’s much more noticeable than on top of a tolex covered cab.
 
I've noticed both magellan heads to be quiet for me. Though my tinnitus may have something to do with that. But, it might be more about how they sit in my basement, where's it's cold and we're seeing snow. I have more time logged with the 350 and I don't recall hearing the fan, given the above.

My only suggestion for the 350 would be to swap the "Active Equalization" and the Bass / Mid / Freq / Treble label positions. When used on a single cab, especially with the combo head bracket, it's difficult to see the writing under the knobs unless you bend over and get at the right angle, which isn't always easy with a bass around your neck. I remedied that with a marker designed for effect pedal setting notations and it rubs off easily. This is a minor "complaint".

I just want to say that, while I was over on the F/S thread about a half dozen reissue Acoustic 360's for sale reminiscing, and I did own one of those bad boys back in the day, I don't think I've ever been more thrilled to own an amp as I am with the 800 especially coupled to the BA12-3.

I was away from playing for a long time and the advances that were made in amplification are mind blowing. The notion of this "building block" method for achieving the best live sound is nothing short of brilliant. When people say we are in a golden age of instruments and amplification, it is truly so. With Jeff and the Genzler products, not only are we in the golden age but we are cutting edge, to boot.
 
With regard to the fan noise, I was playing for the last couple of hours and, at about five feet away, never felt as though the fan generated a noise that was intrusive, in the least. Frankly, I've owned a lot of amps that were much louder sitting at idle and they didn't even have fans. For me, it's a non-issue.

You want to laugh, come listen to my '68 Ampeg Reverbojet. That amp puts out so much noise you have to play loud you so you can hear yourself!!!

Sorry for the delay. Traveling today and will respond more later. The fan is always on but should be very slow unless playing harder/louder. Maybe something we should looking with your unit. Will comment more tonight.
