I've used this box for a couple of years inline with a minicondenser mic on my fiddle and must say that for what it does, it's very well-built and solid, a reliable performer. However I'm planning on replacing mine with a Pro Co Power Mute. Why? Because in the absence of any indicator light it's impossible to know whether the stomp switch is on or off, and this has led to some bad situations in performance. In my opinion a box like this needs some way of indicating whether it's live, whether mechanical or electronic, and this unit doesn't have it. If this isn't an issue for you, go for this box, it's a reliable product. Otherwise I'd recommend spending the extra money for the Power Mute, which has an LED that indicates whether the mic is live or muted.
