I'm still getting used to this new amp. I just can't believe the sheer versatility, its pretty fun. I try to run through most of the features. Most of the demo is on the EL84 with 30 watts on both channels but towards the end I try to show how messing with both wattage and power tube affects the sound. One thing that really helps on the drive channel is keeping the master volume down around 2:00. Any higher and it tends to get unruly.
