Interestingly it has a preamp gain *and* volume, plus a master volume. I haven't quite figured out how they interact yet...
Love the combo though, very happy with it!

This relates to how 'driven' the preamp section is before going through the EQ, the master volume then reproduces what you have told it at the volume you want. If you put the gain on full and the volume down low then crank the master volume up you will get the dirtiest sound, then put the gain as low as it can go, the volume on max and set the master volume this will give you the smoothest tone in can produce. Try volume on half and set the master to suit the room, now adjust the gain pot until you get the sound you want after that use the master volume for any changes you want to make. Like most things you just need to play around with it, and most Genz stuff you just set all the pots to 12 o'clock and enjoy anyway
