I have been a long time MB user. Always loved their stuff. I have used the recording out on my Mk IV with real good results. And have recently picked up a few of their new pedals that came out last year and this year. And these things kick out great tone!
So when I saw this, I started wondering the same thing, how well does it sound?
@bluzdog: It comes in different impedance, 8 and 16 iirc.
@MikeQ: I think they put pics out like that to give you guys (people with know how to build these type of things. Would electronic eng. be correct?) something to wonder about!!
