Yes ^^ all true.Many of us consider that amp with multiple channels, clean dirty more dirty multiple MV and reverb; to be far from simple and even more complicated that a board with dirt pedals and reverb into a one channel one sound amp!
I had a MKIV Boogie and even that was annoyingly complicated for me, though back then I did not use pedals and boards had not yet become a thing.
There was a time when clean dirty and more dirty was all built right in to the guitar colume knob IF you had a simple non MV amp that was not preamp distortion based.
Once amps started simulating cranked amp dirt in multiple preamp sections, amps got VERY COMPLICATED!
Even if the player does not think a well laid out multi channel amp is complicated because each channel has a full set of familiar controls, inside the thing it is VERY complicated.
I am in the market for an amp like that right now and the problem for me is that the dirt channels are as individual as dirt pedals and really kind of the same thing, preamp dirt simulating cranked amp dirt.
If you find an amp you like two or the three channels on?
Can you swap out the channel you do not like for one you do?
A few amps yes, channels are modules.
But most you are stuck trying to make a channel sound right, or else you ignore it and try not to step on the wrong foortswitch button.
Truly simple is straight into a one sound amp and either making the same sound all night or riding the guitar volume for different sounds.
If I really could get away with it, I would use (and have used) a great single channel amp and the guitars volume knob.
It's absolutely my favorite way to play. Cleanish.... to crunchy...to meltdown, all with the twist of the guitar volume knob.
The reason I abandoned that is because often times, I need to have pristine clean or jazzy clean sounds. In the same song I may have to melt faces with a lead. Too tall an order for a single channel amp.
