DIY – RM-5 Ribbon Mic Build
So a few weeks back I snagged this ribbon mic kit over at www.diyrecordingequipment.com
Really simple nice sounding mic. Highly recommend Artur’s “official” retail RM-5 for anyone looking to get their hands on one of these.
After it was wired up, I pulled a few coworkers into a booth to make sure it passed signal. I setup a VERY informal comparison. I recorded it side by side with a 416 via a Hardy M1 pre. No processing, EQ or compression. For vocal tasks I recommend having 80dB of gain or so. I’m very pleased with the mic, I’ll be putting it up on Rhodes & Drum duty shortly.

DIY TB550A
Finished this guy up tonight (TB550A). Not the easiest of builds, as mentioned patience is key. I made a couple careless mistakes along the way, but all are resolved. TIP – Triple check alignment/orientations at all stages. For the time being I’ve loaded it up with a pair of 990′s & a CMOQ-2S. I might swap out the 990′s at some point, but I have to say it’s performing very well as is. Great EQ kit.
This is a quick test with the EQ on a solo kick batter mic. With & without the EQ active. Pretty amazing difference, the EQ is last in the chain with no other influence.
Time-lapse video / optical synth control experiment.
While getting familiar with the d5100′s time-lapse & video capabilities, the idea of video controlled synthesis came to mind. I unsuccessfully scanned the net looking for a something to generate midi from video. While staring off into space a psychical solution was staring back at me. My Thingamagoop 2. I ended up using it’s photocell eye to pick up the changes of light from my video experiments.
Laid down some drum noodling & patched the CV output from the Thingamagoop into the pitch input of a Moog Voyager. I recorded one Bass & one Lead pass & called it a day. “Controlled Chaos”
Evil toy piano shootout
As posted via recordinghacks.com
I recently scored this wonderful, but horribly pink toy piano. I found this to be a perfect opportunity to experiment with a few mic techniques. That, and I can never turn down the opportunity for over-the-top ridiculousness.
I decided to try out a pair of 414s, a large diaphragm Red, & a self-made piezo contact mic. I setup the 414s in a 90° stereo configuration over the hammers, but quickly found some severe phase issues. I then tried a simple left & right spaced configuration that had similar results. I opted to use a M/S configuration for a more “phase friendly placement,” and the ability to control the width as needed. For the Red I placed it behind the open lid to capture the overall tone of the piano. For fun, I taped a rat-shack sourced piezo element directly to the tone-board.
The Gear
- 2x AKG C 414 B-ULS via ADL-600
- Red Type B with R8 Capsule via API-312
- DIY Piezo contact mic via API-312
The Verdict
The M/S pair sounds great. Nice stereo image, accurately captures the direct sound. Even picks up the key press noise position. The Red sounds nice as well, more ambient room tone. I really enjoyed the piezo, & love the LoFi character.
For the current track I’m using this with, I’m thinking I will use a mix of the bunch. I’ll most likely make a very wide image from the M/S pair, then use the Red/Piezo to pull in the center image.

When Eric posted these photos to Twitter, I couldn’t resist asking him to write about the session. There’s just something awesome about miking a toy piano with $5000 worth of gear. Well, $5003.95 if you include the piezo.
What’s great about it is not just that all three tracks sound different, but that each mic captures a wholly different vibe. Each is usable in its way, but each brings something different to the production. Having all these choices will make the mix that much more interesting.
