Yes I’m one of those dirt mongers... it was a pretty easy build even with the latching jack mod... ( if you do it... make sure to measure and drill carefully there really isn’t a lot of room for error in that spot.) it only had one knob so I had to make it a little more fun. Sounds good nice clean tight boost for extended range and low tuned guitars. Used the Bc550b instead of the C and it worked out just fine.... yes I plugged in the extra transistor and resistors because I was in the zone and wasn’t thinking... I guess it looks cleaner with no open holes right?
Here is a quick vid of the latching function nothing super crazy.
