This is an older video, and there may or may not be another thread about it, but I just happened to stumble across it. A lot of people seem to ask what the tonal differences between the new Dual Rec and a Tremoverb are, while I'm not a fan of his playing, you definitely can distinguish the differences. I'm definitely a fan of the Tremoverb, much smoother with less fizz.
