Due to me being incapable of not messing with things..... even if they work...... I decided to put the above blender into my Joyo American Sound pedal. The pedal isn't true bypass which caused a lot of head scratching to begin with but, as the American Sound is an 'always on' pedal for me, I took the footswitch out and un-soldered the plastic board-mounted jack sockets, and then soldered send and return leads to the places where the jack-socket tips made their connection to the circuit board. I needed to put a jumper wire (little white loop at the bottom of the circuit board) to get round the not true-bypass signal in.
If you're temped to do the same thing, then after de-soldering the foot switch you're left with 6 empty connections. Going from left to right, 1&2 are LED connections (I wired the LED direct to the 9V in as it's always on), then jumper 3&5 (signal in) and jumper 4&6 (signal out). There's no 4&6 jumper wire on mine 'cos I trashed the signal out connection point trace when removing the out jack socket. My signal out is taken directly off hole #4. I also jumpered the 'battery earth switch' at the input jack where the stereo socket makes the connection with the input jack sleeve.
