Where do they say anything about a 5 year warranty? This is all I could find from their manuals. Assuming their information is correct, the warranty is void the moment you begin assembly. I understand the point that they're cheaper and allegedly the same or "improved" components, but there's no guarantee, and you'd need an original anyway to see if your ear agrees that they're the same. You'll pay more for a branded pedal from a shop and may have difficulty finding what you're looking for, but you've got a better chance of being able to return it if you get screwed. It's always a gamble to an extent.
BYOC, LLC guarantees that your kit will be complete and that all parts and components
will arrive as described, functioning and free of defect. Soldering, clipping, cutting,
stripping, or using any of the components in any way voids this guarantee. BYOC, LLC
guarantees that the instructions for your kit will be free of any majors errors that would
cause you to permanently damage any components in your kit, but does not guarantee
that the instructions will be free of typos or minor errors. BYOC, LLC does not
warranty the completed pedal as a whole functioning unit nor do we warranty any of the
individual parts once they have been used. If you have a component that is used, but
feel it was defective prior to you using it, we reserve the right to determine whether or
not the component was faulty upon arrival. Please direct all warranty issues to:
This would include any missing parts issues
Edit: All that said, there's no denying they have happy customers and a great reputation, and I still want to build one. At times I hate being so frugal, especially with music gear. I spend at least an hour every day playing, but it's still difficult convincing myself to spend a few hundred here and there. It almost killed me spending $1100 on a guitar earlier this year, but I feel like I've already gotten my money's worth...when I first started playing, I worked a summer job reffing and used every dime of it to buy a Les Paul Studio in that translucent wine finish. Beautiful guitar, I had crazy buyer's remorse and returned it a week later, lol.
