Thank you Chuck!
Currently I am eagerly awaiting the arrival of SP-CMC4s with cardioid capsules I bought at the yard sale, but I also want omnis. Yes, I do want to record unamplified music and ambience. I use a 9 Volt powered preamp which supplies 9 Volt power to the mics. With the preamp added, could Jon's omnis be a good choice, or would the omni capsules for the CMC4s, which I'd hope to get at the yard, my best choice? BTW I have Giant Squid Omnis, but I'd suppose that both, Jon's and the omni capsules for the CMCs should be quite superior, yes?
The preamp is quite basic though, it's an unknown model only sold in Japan. The specs look like this: ( some odd automatic translations included )
