Not real sure what I think. Prior to trying it I was re-adjusting the amp and found out that I liked the dirty channel better with the extra drive stage on, extra drive pot at 3:00, channel gain at 10:00. The gain pot seems to be the culprit that makes the dirty channel have a grainy muddy sound. So anyway, I did the mod and I'm unsure if I like it as well as the way I had re-adjusted the amp prior to the mod... Just thinking out loud.
