This is a boost pedal designed after a Landgraff Boost (very similar to the Zvex SHO) and a Fulltone Fat Boost; it contains both circuits which run independently. Between these two pedals you can get an extremely wide range of clean boost sound- if you’re in to that sort of thing.
As you can see, it is a bit crowded inside, but not unreasonably so. It still has plenty of access to make any modifications or fixes, should the need ever arrive. The knobs had to be placed on the top of the pedal, because the potentiometers would have been in the way of the circuits inside otherwise.
update: This may or may not have been used in the new Camera Obscura album. But it totally was.
