BJF (and now Mad Professor) pedals are handmade in Stockholm, Sweden by Bjorn Ruhl, leaning towards original and innovative circuits as opposed to copying the cookbook distortions that have been adapted and modified into pedals for the last forty years or so. His "color" distortions and overdrives (Dyna Red, Baby Blue, Emerald Green Distortion Machine, Pink Purple Fuzz, etc) are stunningly good, and there are branches out in the BJF line into EQ-drive-boosters, vibes, compressors; Bjorn is something of a darling in the boutique pedal world
The downside is that these pedals are prohibitively expensive: most of these pedals clock in at about $300, which can mostly be attributed to the flaccid US dollar and the importing of these puppies from Sweden. The one BJF pedal I own was something I shopped for and distinctively needed-- a buffer/booster. Not sexy at all, I know (BJF makes much cooler pedals than this) but shopping around, this is the only booster I could find that had a rock-solid buffer and strong input impendence even when bypassed (there was a ZVex pedal in the running, but the true bypass switching defeated my purpose), and this thing sounds great.
BJF pedals are hand painted boxes, and... well, the finish is a little delicate. I never really cared about things like that. I think it gives a pedal a well loved, lived-in quality.
