My first 1590A build was an lpb1 I called it the elevenizer. I used beans drill template to see if I could actually get something in to a box that small.
Well it worked and now I'm building a bunch of baby boards really love them. Below is a picture o my afterlife and my cave dweller. I really like them both. The afterlife is great, subtle but great. The cave dweller is pretty amazing. Given the low parts count I'm amazed it works as well as it does. Both easy builds too.

Nice! Now you need to build a really small pedal board.
