Special OP-6 mic preamp (ex-demo)

# ONE EX-DEMO UNIT # Available right now! Build spec is Line inputs on the "INPUT 2", Saturating Attenuator, wooden panel...

The Special OP-6 microphone amplifier is a handmade unit of the highest quality, built here in our workshop in Reykjavík, Iceland. It is the result of many years of obsessive work analyzing and replicating an original RCA OP-6, right down to the core of the transformers using X-Ray and CT scan. We improved upon the original in a number of ways, one of them being noise floor. Our unit is quieter than any vintage OP6 out there. We also broadened the gain range to 40-84dB. Added features include instrument input, phantom power (slow ramped), input impedance, pad, and polarity flip switches, plus our own unique saturating output attenuator. This attenuator not only pulls back the hot output when driving the preamp hard, but it also draws out more harmonic content than a normal attenuator, meaning that you get a fatter, fuller driven sound that is blooming with overtones. We used to offer a normal attenuator option but nobody wanted it once they heard our saturating version :).

This listing is for a stereo/dual unit with two channels. It is now available in both the plywood panel with black knobs, and a wrinkle painted metal panel with solid aluminium knobs. We also offer a cheaper, mono roadcased version. Please see our other listing for that one...

As well as the instrument inputs on the front there are two XLR inputs per channel on the rear, the second of which can be configured as either a mic input or a line input. It can also have phantom power disabled if you like, making that input ideal for your precious vintage ribbon mics.

The video link below is an example of the sound of our preamp. In this session with Ásgeir it was used on the main vocal (RCA 77c1) and on the spot mic on the guitar itself. Reverb does not allow URLs in the listing but DM us and we will send you a link to more audio samples of the preamp in action. We also got a nice review in Sound on Sound magazine, which you can find on their website.
