Small external mic for po33 and op-1?

Hi all!
Anyone tried external mic for po33 or op-1?

For OP-1, I’ve used a Sony MS907 with good results. I know others who have used an Audiotechnica Pro-24.

@5StarNomad thank you

I made myself a microphone like this https://www.youtube.com/watch?v=BsvbJ5nLJDA
The Signal is a bit low but still works fine.

I’ve been curious about getting a Sony MS907 for a while for the OP1…is the mic signal weak (like a lot of other mics on the op1)?

Should OP-1 recognize microphones? When I connect a normal mic to the inputs, it just treats it as line-in.
