Code 25. Set Master volume by software?


I find my Code 25 amp too loud at practice levels (at least for my apartment) so I have to set the Master Volume between 0.1-0.9 and in that  range the Master Volume varies greatly which makes almost impossible to adjust it at the same value twice.

It will be nice if the Master knob could also be set via software so it can be saved/stored and also displayed in the amp's front panel screen, since it is very common to move the amp from one room to another and accidentally change the Master setting without knowing at what level it was previously set.
Coud be possible to add this option in a future firmware/app update?

Thanks in advance!

I have the same problem, but in my case until 0.89999 is too low and the moment you hit 0.9 then is too loud for my apartment. it is almost impossible to dial an even volume. What I have done is leaving my master volume in too loud and then turn the volume down on my phone app... but I think it affects the tone. - diego morel 04 Jan 2017 at 04:39 PM

Dear Marshall Team,
are there any updates concerning this issue? With the last firmware update nothing really happened. The Master Volume is still not working properly..

Best Regards

Hi there,

I have the same problem with the master volume. Between 0 and 0.9 nothing really happens, when you reach 1 to 1.1 it's getting really loud - nearly too loud for apartment use.  When you adjust the volume knob, you also change the preset itself, which is not the solution.

An update will be great. I really love my Code25, but this problem is a bit annoying.

Best Regard
