If you are in to high gain amps and looking for something portable with great tone, this is a steal. The difference with the regular 6l6 is a change in the voicing, shifting the mids higher and adding low end, making it feel clearer and more precise.
Green channel: Amazing bell like type cleans that didn't expect. Put a strat on it and will give a fat clear sound all day.
Blue channel: Amazin, rich distortion with lots of high mids and clarity. It is as tight as it needs to be to have low end clarity but at the same time feels big with lots of body. The distortion has a dry character (not too spongy, saggy) taking od pedals in front extremely well, as it makes it more compressed and easier in the fingers. Also, try putting low output pickups with the gain below noon, to get a plexi on 10 like tone.
Red channel: Laughable amounts of gain that can get very easily over the top. I try to eq it to get as close to the Blue, while being a bit gainier and fuller sounding for lead work. Sustain for days!!!
Extra Info:
- The amp has so much gain that can sound good at very low volumes. Having said that, i feel that even when pushing the master past 1, it becomes a different beast.
- The footswitch is built like a tank and feels rock solid.
Overall, it is the best high gain amp for the market it competes in. Buy it without a second thought.
