They sound pretty close. I don't think they are exactly the same, and you can dial the EQ to make it more different. So you can use it as a second channel, or a clean boost, or a dirty boost, or a mid-boost without too much effort and without it drastically changing the sound. I really like that about it! I don't think it's too much of the same thing because of how I'm using it (slightly dirty slightly mid-boosted). I set my Monarch on edge-of-breakup so it still has some clean room if I need it. It's very dynamic.
