My test bench has for many years had a couple of ground isolated Neve 1:1
transformers between XLR input test sockets and stereo monitors.

Which has never been a problem, but has ALWAYS been a problem connecting any
CryBaby Wah Wah pedal.

If you do, the CryBaby resonates at full volume, behaving much like turning
a VCF resonance control to full, so it self oscillates.
Why is that?

I guess that means you could never directly connect a CryBaby to any
transformer balanced mixer input.
