Hi everyone! I’m new in the forum. I’ve searched all over the web and I couldn’t found anything about this mod. I would like to replace the stock power supply input jack (a 3.5mm mono miniplug like the one in the picture number 1) by a boss-style one (like in the picture number 2), but I don’t have much knowledge about electronics, so I would like to know where to solder each cable that comes from the board to the barrel dc jack. I assume that cable number 1 is ground connection, because it goes to a screw in the chassis of the pedal, number 2 goes to the board and then to the 9v battery and 3… I really don’t know where it goes, besides all this, there’s the black cable that goes to the 9v battery too… and also, I need to “reverse the polarity” of the jack to be able to plug it to a center negative adapter with a barrel plug. I apologize if there is any grammatical error, I speak spanish haha. Thanks in advance for the help, best regards!
