ok built a hot wired from here http://tagboardeffects.blogspot.com/2017/11/wampler-hot-wired-v1.html
Ch1 works great, ch 2 is where the problem is, it has a weird distortion to it. hard to explain.
used a jrc 4580DD using 9v the readings on 5-6-7 don't seem right to me.have reflowed the solder checked for bridges and rechecked all hookups
1 4.55
2 4.54
3 4.1
4 0
5 0.46
6 8.33
7 8.50
8 9.0

Then you should measure 4.48V on pin 5..
(unless there is some light short between pins 4 & 5..)

Power off, take off IC and measure continuity between pins 4 & 5..
