Things With Strings

Buoyed by the success of last month's " Chafer Drive ", I've been busy drawing up layouts for a few more small effects that I want to build, and first up is a tribute to the " Shin Ei Companion Fuzz FY-2 ". This was a Japanese fuzz pedal made in the 1970's and is generally well-regarded in the DIY effects community for it's classic fuzz tones. The original came in a large wedge shaped box, but my plan was to squeeze it into a Hammond 1590A  just as I did with the " Chafer Drive ". This was undoubtedly going to be more challenging, since (a) the circuit is larger, and (b) it has two control knobs as opposed to one. I had some standard 25 x 9 stripboard  which I thought would be ideal for this purpose, so I challenged myself to layout the circuit with that in mind. The original circuit use some obscure  2SC536 transistors (Hfe 160-560) that were no longer manufactured,  but I had a whole bunch of 2SC1685  (Hfe 160-460) transistors that I
