Placid Audio Copperphone (Demo Deal) – No Longer Available

Lo-fi dynamic effects microphone that reproducing a limited bandwidth of frequencies reminiscent of a telephone or AM radio

Product Description

Conjuring up a bygone age in both sound and appearance, the Placid Audio Copperphone is a lo-fi dynamic effects microphone that reproduces a limited bandwidth of frequencies reminiscent of a telephone or AM radio. Handcrafted in Texas from vintage telecommunications components, it achieves its nostalgic lo-fi sound by combining a mic element and mechanical filtering, accentuating upper midrange frequencies and attenuating low and high frequencies.

You can use The Copperphone as a standalone effects mic to add authentic vintage character to any voice or instrument. Or pair it with another more traditional microphone in any number of configurations, with or without processing, and blend the two signals to create something unique and interesting.

The Copperphone has been adopted by engineers, producers, and recording studios worldwide, but it’s just as effective in a live situation. In fact, company founder Mark Pirro, an engineer and bass player with Polyphonic Spree, originally designed The Copperphone for the band’s lead singer, Tim DeLaughter — so rest assured that it’s built to take the rigors of the road, too.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
