I liked plain ol' channel 3 the most. Channel 4 isn't bad, but too much gain for my taste. And the boosted clip just sounded louder and a little more gain. Also are the knobs in the vid/photos where your settings were? Gain maxed???? Mids almost off???? I'd love to hear the same test recorded with the mids on channel 3 up past 1:00 at least and the gain backed down to maybe 2:00. I know it's all subjective and the style of music you're playing comes into account though
