After two of these, I'm done
It really seems like a good quality volume pedal is one of the hardest things to come by these days. You end up losing in functionality, sound quality, or construction. With the VP Jr., my main complaint is the construction. The first one I bought was returned immediately because of a scratchy pot. The second one lasted just over a year before it started developing problems that impeded its functionality. The sound would not cut out completely in the heel back position, and eventually the string broke. Please note, the string WILL break in these pedals at some point. It's just a matter of time and how much you use the pedal. It's a relatively cheap fix, but aggravating and risky for the gigging musician. There's also of course the tone deterioration factor, which is just present enough to be noticeable. This never bothered me as much as it seems to peeve other players, but it's still something to be considered if you're really into preserving tone over the signal chain. Overall, the action and feel of the pedal are just fine, as is the sound of the swell it produces. Just don't expect a lot of mileage out of these before they give out in one way or another. Virtually every guitarist I know who has played with one of these has the same complaints. It seems if you want a pedal that will not only sound great but also stand the test of time, you have to spend a little more.
