Yeah, sounds like you answered your own question in the edit. D1/D2 are clipping, the other LED's are in the power section and indicate the stomp switch status.
Got it! Thanks.
Just started out again after 10 years. Quick paint by numbers built for me, everything installed and boxed up. Just to take it apart again. Oh well
I thought the two LED pairs were alternative locations of the stomp switch status.
Odd location for an untrained eye.
