When I bought the unit, I believed it was almost going to be a 'plug-in and play experience.' I've wired up guitars before, less than five, but I've also built my own pedals through kits as well, so I'm comfortable soldering. This was supposed to be easy, and I paid extra to save my time. Unfortunately, there was a significant problem with how the capacitor was seated in this particular harness. What's more, both the capacitor wire was hitting the pot, grounding it. Another lug was also being errantly grounded. I wrote directly to Mojotone and asked for support. The support eventually started to ignore me. Whilst I prefer to give products a high review, this product simply was crafted poorly. I believe the company should test these units with alligator clips before shipping them out. This way, they'll solve issues and low-scoring reviews.
