I've had my eye on this guy for a while now. I sold some stuff and pulled the trigger last night. I'm using the direct recording out into my Native Instruments Session I/O interface. Plugged in with a PRS CE24. I'm still getting a feel for it. Here I go through the clean and dirty channels with some basic EQ settings. I stick solely to the 6V6 power tubes and 30W on both channels. The clean channel has the bright switch on.
An initial reaction - the knobs are extremely impactful. Altering the EQ, toggle switches, or drive/volume knobs can drastically alter your tone. Messing with the Wattage/Tube Mix knobs really changes the feel.
A few things from the manual - the Wattage knob doesn't impact the volume as the "headroom". Lower watts is still loud, but more compressed and spongy. Also the Tube Mix knob creates some subtle differences. Moving from pure EL84 to pure 6V6 creates a different feel, but it really doesn't radically transform the amp from American to British. Also, the amp puts out 30 watts when the tube mix is 50/50. When you are pure EL84 or 6V6 it puts out 20 Watts.
