This one sounds really good to me too, and seeing that his sky blue is the closest thing to a Dumble I have tried yet, I ordered one. It should be here by Monday, and I will make some A/B/C clips of the Quinn, the Sky Blue, and the Simble.
I'm going to order one, too. The video shows it sounds good with an old Marshall, and since my HXDA isn't far off that design, I figure it'll be a pretty good pedal for me as well.
Right now my priority is elsewhere, but in a couple of weeks it's a go.
