For anyone who gets the Tone Report online newsletter each week, you may have noticed that a few recent issues have had articles describing how to build a few pedals. I think there were things like a vico-vibe trem, a Big muff varient, a couple fuzz pedals, and even a miniature amp in a stompbox format in this past week's issue. Has anyone tried building any of these? Any thoughts on the build process for them, as well as the sound? Are they worth trying? I've been thinking of making the vico vibe/trem, but I've heard things about how there's a noticeable loss of volume when the effect is on.
