am a noob to building pedals but I can follow directions pretty well. I haven't used effects that much because I didn't like the tone suck. I found the B.Blender and I thought it would be a good pedal that will help alleviate that. I have made the PCB, populated the board and I am starting to do the off board wiring. I am following this picture; have a question regarding the yellow lead coming from the board pin 2 volume that goes to the switch. When I wire the volume pot, do I leave pin 2 of the pot unwired? or do I also run a lead from pin 2 of the board to pin 2 of the pot as well? The layout doesn't have the volume and blend pots shown. I am also going to wire in a 9v and I've changed the In jack to stereo. Thanks in advance for any help/guidance you can give me.
