Is the Vox AC15's master volume placed in the signal chain of the amp so that when it's completely cranked, it's almost like it's out of the chain entirely? I'm not sure if I'm asking that correctly. I've seen people say the same of the Blues Jr. So I'm wondering if it applies to most master volume amps (I've read it has to do where the MV is in relation to the phase inverters). Also, if cranking the MV to "get it out of the way" makes it more like a non-MV amp, when you turn up the volume knob to break up, is that break up more like the break up of a non-MV amp? Basically, when I turn my DR to about 5.5-6, it breaks up. Is the same effect happening when I turn the Vox MV all the way up then turn the volume up to when it starts to break?
