Alright so ive probed and stared at this long enough. I need some different eyes.

This is a 3 in 1 build i am building for a friend of mine. Angry charlie/bootleg/glory hole.

Issue on the glory hole. Unity is volume at max. Audio probe everything seems like what id expect following the signal. Bit if a volume boost at ic pin 1, bigger one at pin 7. Little quieter at the output of the tone pot.

5457 gate and drain are the same volume.

Voltages are
D-0
S- 1.0
G- 7.18

1 - 4.6
2 - 4.6
3 - 4.3
4 - 0
5 4.53
6 - 4.53
7 - 4.5
8 - 9.05

5457 came from stompbox parts. Ive used several from the batch i ordered no issues. Tried a different one from the baggy just to see no change.

my jacks are wired with switched jacks. Kind of like the duo phase. I tend to think these are ok
as everythign works great til you to the glory hole
On.

Pics at angle due to lighting.
