Man, I don't know they have been on my radar for years. I hear good stuff about them, specifically the 22 watt and the 100w. The 60w version is less revered, but I cant remember why. I like heads and Fender doesn't do many modern heads so it's appealing there.
Where I personally land on them every time I see one pop up is they are cool, sound good, but there are better options if you want clean and better options if you want to gain. Not that either are bad, and if you needed both in one head, it will do well. I'm sure I'll pick one up someday and find out.
Will it chug? I can't say for sure.
