Yeah ! Thank you for your answer.

I've seen peng3002 swapping results :

MAX437 - I couldn't detect a difference.
OP27 - same.
OP275 - same. This distorted earlier as I raised the input level.
OPA2134 - same

Arghhhh !I have a small stock of expensive op275...

All in all, TL7x are quite good chips compared to the uA741s that
feed most of my pedal/box effect !

Thank you Ken ! ;-)
