First off, I'm a very experienced electric guitarist and I generally know how virtual controls map to the real world controls in amp modeling software. However, I cannot figure out what the difference is between the Master and Output controls on the Blackface Combo model.


I'm very disappointed that the GB online help doesn't document this.


Does anyone know how these controls function?

    I'm pretty sure the output is just to control gain of the overall amp sim. This lets the master channel simulate the master stage of a tube amp. As you know cranking the master stage of a amp lets you get a hot power tube saturation that you don't get by just driving preamp tubes. I think Apple is letting us simulate the pre and power section of a amp so it works just like a real amp and not overdriving garagebands master track.
