You could barely build out a homebrew of this quality parts for what these loop pedals sell for. The build quality is awesome and they work great.
But.............
he takes at least 45 days to ship. So you order and wait until the season changes to get your product. I bought a second single loop switch thinking it couldn't possibly take that long to ship again and it took two weeks longer. However, he builds great pedals that are stupid low priced. The only other neg I'll note is that not all of the colors of LEDs have the same brightness... (picky, picky- I know)
If waiting doesn't bother you it is a great product at a low price.
I use a dual looper with a tuner out (which makes a great mute switch for the rig) on my Studio 22+. I'm thinking about ordering an aby with a tuner out one for a new switching clusterfap I just imagined.
