I built this one over the last week or so. I managed to stuff it into a 1590B - it's tight, but it fits - and the wiring is slightly messy but the extra length was needed to squeeze it in there. You might notice I didn't have quite all the cap values called for in the BOM - I made do with some parallel caps. Box art is, well, Plain Jane, but I honestly couldn't be bothered to come up with a clever name or print decals or anything, and I had some rub-on letters I've been wanting to test on something. The sound of this pedal more than makes up for it.

Whew! Nice engineering on the arrangement. Not a lot of room to spare, but it looks nice and tidy.
