What is Bricolage?

Bricolage is a term for the art known as “assemblage”: artwork made from found or re-purposed objects and materials. In Europe it also has taken on a meaning of DIY; hardware stores– known as “DIY shops” in the UK, a term I’ve always loved– are also frequently referred to with some version of the word bricolage. The core meaning of the root French word is, “fiddle, tinker” and, by extension,

To make creative and resourceful use of whatever materials are at hand (regardless of their original purpose)

I love this as a description of what we do here at Ear Trumpet Labs. We are tinkerers and artists. We are always up for doing custom work. When I started making microphones I was immediately drawn to the possibility of making the housings from all sorts of things. Early microphone designs from the 1930s and 40s strike a balance between beauty and functionality, while most commercially-available modern microphones seem painfully dull. I don’t reproduce old designs, I tinker with hardware, surplus scraps, and everyday objects until I find an assemblage that is both beautiful and functional. Some of our products recall the elegant mic designs of the early broadcast era; others evoke early industrial aesthetics. There are always more exciting designs in our heads and under development.

My approach to the acoustics and electronics of our microphones is bricolage of another sort. There is an enormous wealth of public information available on very high quality mic circuit designs. I pick and choose designs that suit each mic, the capsules used, and the mic’s purpose. I try to apply publicly available designs to found objects with a little ingenuity and a lot of care. 

We are committed to supporting the DIY community. The schematic of our most common microphone circuit is essentially a variation on the venerable, versatile, and extremely clever transformerless FET Schoeps circuit widely used by commercial manufacturers and home builders alike, as well as for upgrades and mods of lesser commercial mics.

 

Can I use Ear Trumpet Labs mics with a tower array PA like Bose L1?

We have worked with a number of artists using these tower array systems like the Bose L1 or the Fishman SA330x. There are a lot of benefits to these portable systems, and they have great sound quality that suit our mics well. The main thing to keep in mind, though, is that when condenser micing the claim that you can have the column behind you without concern for feedback is not true, especially if you're single micing which can require a large amount of gain. Having a mic with the sensitivity and gain to give decent volume to an instrument 3 feet away, pointed at a reproducing speaker only an additional six feet away in the same direction, is never going to work. However, people have had success placing the column just about level with the mic, not too close, especially if they can angle the mic a bit away from the column. Generally you can then hear yourself well enough from the edge of the column's pattern, but the mic and the speaker are both in areas of lower sensitivity with respect to each other, so you can get the volume out to the room pretty high. You can also add a floor monitor out in front of you for added volume on stage.

I’m really into this stuff— how can I find out more?

For anyone who is interested in diving deep into the dark arts of microphone making, here is the video of a talk I gave at the Curiosity Club here in Portland. There’s some tech talk about the many ways of transducing sound waves to electrical signals, the ins and outs of a weird DIY niche community, making cool useful things from metal with no machining skills at all, the path from hobby to obsession to business, and the pleasures of the toolmaker in seeing their tools well used.

If you’d like to talk more, please shoot us an email, give us a call (503-974-4147), or come visit our lab in Portland, Oregon!

What mic clips do you recommend?

We make our own Copper Mic Clip and Brass Shock Mount if you’d like a hand-made clip that matches the aesthetic of your microphone.

Our mics also fit in standard plastic Shure A25 clips that you would use for a 58 and we include one with every order. They can be a bit tough to snap on – you can’t slide them in because of the flange at the bottom of the mic – but the Shure clips are really unbreakable and very secure once you snap the mics in. If you lose yours or need a spare, let us know and we’re happy to sell you another for $5 plus shipping.
