HI Max,
I've never sold anything good without regretting it later (usually within a
week!). A couple of those guitars would buy me a lovely mic closet today.

I took the Sony ECM MS907 out this morning. Terrible day for air traffic. I
was on the edge of the city. Things are pretty slow for wildlife sounds
around here at this time of year (and at my skill level), so it won't sound
like my uncle's English country garden in Norwich!

It's pretty hissy, but not the most objectionable hiss I've ever heard. The
MS907 is plugged into a Marantz PMD 661 with the gain set to 8. I haven't
applied any EQ, or postGain; just chopped and x-faded. At 2:12 I replay the
last few seconds with some gentle denoising (Voxengo Redunoise --signature
acquired from the under-the-bedclothes test) with 2db of makeup gain.
Temperature is about 4=B0C, gently breezy and you'll hear some snow falling
off trees in the sun. The creek will perhaps give a better idea of the
imaging at 120=B0, which hasn't been altered.  I'm guessing this would be
similar to the HD-P2 at about 7-7.5, as the Marantz pre's seem to offer a
little more, and quieter gain.

I also met a new

made my day -love these image-stabilizing tele's!
