This is a drumkit recording made at jackinthebox Studios using three Opal OM7 LDC Tube Mics in a Glyn Johns formation. The first mic is one meter above the snare and panned slightly to the right. The second mic is one meter from the centre of the snare pointing at the snare over the rim of the floor tom and panned slightly to the left. The third is pointing at the middle of the front head of the bass drum, about 8 inches out, also a meter from the middle of the snare for phase coherency. This file is 24bit 44.1khz with no treatment at all. A Voxengo Elephant limiter was used to bring the file up to full volume but with zero gain reduction. The recording is the Property of Velvet Stream.

The capsule and valve as well as the power supply are unchanged.

Winter In Ontario by the lovely Kirsty Merryn. Recorded at Jackinthebox Studios in May 2012. My Ancient Hungarian grand piano recorded with an MS pair with an OM7 custom for the mid and a Coles 4038 for the side. Vocals recorded with the same OM7 custom modified with a Cinemag 2461NiCo transformer, a BeezNeez K7 capsule, Mundorf M-Cap capacitors and silver teflon wiring. Also custom painted white and the headbasket and grille rebuilt with three layer mesh. Serial number 001. Cadac A type preamp. UA 1176 compressor, Summit EQ200B, PCM60 reverb and UAD EMT140 plate.
I was commissioned by Steve Mackey to build him a U47 and this is the result so far!
