Sort of a dumpster find, a friend gave me three Sony ECM 44B Lav mics, along with a Shure mixer, that were being thrown away from a hospital's Sleep Study program. They seem to be in bad shape, cuts in the wires to the capsules, etc. However, if I find that they work, or I can repair them, I thought of using them as perhaps room mics, by hanging them unobtrusively from the ceilings or, perhaps, trying one inside an acoustic guitar. They are battery-powered omnis with a 40 to 15k frequency response. Anyone familiar with these and have any thoughts?

Omni lav's are very usefull, free is free and Sonys are a staple, but Sony ECM Electerets are known for losing charge and output.
Good news parts are available.

I figured I should put in a good supply of batteries. Thanks for the reply

You could try mocking up a human head and putting them where the "ears" would be. Do some reading on Tchad Blake - pretty sure he used to do this before he got his Neumann head mic.

I'm not directly familiar with the ECM44 but I believe they're similar to the two Sony lavs I have, an ECM50 and an ECM55, which are the the same mic except for the type of battery used. Thay're great mics for a lot of things. I've used them hung inside an upright piano to unobtrusively record without having mic stands all over the place. They can be useful to mic a gong because you can hang it just inside the lip and it won't get in the way when the gong swings. They're useful for all kinds of oddball stuff.
The newer Sonys do not have the same problem with losing charge that the first ones did. Mine are around 30-35 years old and still going strong.
The ECM-44 does not support phantom power, unlike the other Sony lavs.
