I have built the new Bloviator 2017 twice. Each time, I get no output with the switch engaged. Led lights up, but no sound. I do get sound through bypass though. The first time I built it, I thought I thought I might have put the pots on opposite, so I ordered another board. Built it again, this time with a 3DPT board for the switch to ensure no problems in hooking up the wiring. The second time, I also used a multi meter to hand select each resistor to match spec. I used a microscope to ensure there were no solder points touching each other, and used 20 gauge wire to ensure no broken leads. I switched out the op amps when things didnt work and still no result. I am an experienced builder, but this one has made me nuts. And yes, I have reheated the solder points to find any cold solder joints. No luck.
