Kingslayer II IC's

[jtaormina]

Curious which IC choices people who have built the Kingslayer II used.  I found another thread that said to use TLC074 to get rid of the squeal which totally worked. I also used the TC1044SCPA charge pump. This seems to work fine, pedal sounds good normally. But it gets a squeak that fades out when disconnecting power.   No idea why. I was thinking the charge pump could cause it. The KIngslayer I document mentions something to this effect.  Anyone get that fading squeak?
