|Sony F-V300 and C38b microphones|
This example has some traces of foam around the element, indicating that an internal windshield has at some time been removed.
The label states that the mic is nominally of 1kΩ impedance, although in practice seems lower than this and it has no problems driving standard low-Z microphone preamps. The output is strong and clear across the range, and the output is similar in level and detail to a healthy EV RE20, although with a more pronounced proximity effect.
As far as we know, this microphone was only marketed in Japan, but if you have any information to confirm or deny this, or in fact any information about this mic at all, please let us know!
This microphone has become a bit of a favourite for guitar cabs - it seems to have just the right amount of proximity boost for that application, giving clear and solid presence to the lower end. It also makes a decent tom mic.
