Nu Series v2
The Nu Series Modular Active Pickups are hacker friendly, general purpose pickups that can be used in a variety of applications. These are active pickups utilizing low impedance coils, permalloy ring shields to minimize crosstalk, and an integrated differential, low-power, low-noise preamplifier for each coil. These small pickups are modular and can be used individually or in groups.
The pickups are designed for multichannel processing — one for each string (distortion, EQ, compressor, delay, pan, pitch-shift, etc). Such extensive processing is now possible due to advances in digital signal processing and the proliferation of multi-channel audio interfaces and multi-track audio software.
These modular pickups are not just for guitars. Nus are also successfully utilized in other musical instruments such as the bass guitar, cellos, harps, pianos, etc.
The Nu Series active polyphonic pickups have a uniform frequency response from 20Hz to 20Khz. The sound is very clean with lots of overtones and crystal clear highs. The low impedance coils give the pickups its characteristic wide bandwidth.
Unlike traditional high-impedance passive pickups, there are no big peaks and dips in the response. Such a wide and flat frequency response gives you the freedom to sculpt the tone using analog or digital filters. The low-impedance pickup imparts very little coloration to the guitar sound. You get whatever tone you want using appropriate tone shaping EQ rather than a fixed, predetermined guitar tone.
See Sculpting the Tone for details and more sound clips.
Here’s a short clip with a “classical” EQ capture of the Cycfi Nu multichannel pickup mounted on a Fender Stratocaster in the bridge position. The strings are panned from right to left, with the low-E at the right and the high-E at the left. Get your best headset ready or run the sound clips through your awesome cool stereo system.

Nu Multi Standard vs. Basic
The only difference between the Nu Multi Standard and Nu Multi Basic (available as options) is the inclusion of the Internal breakout (see below). The Nu Multi Basic does not include the Internal breakout.
The Nu Multi Basic by itself has all the power, signal and ground connectors available that you can use to connect to whatever audio input devices you wish to connect to. The Internal breakout that comes with the Nu Multi Standard expands the inputs to other audio sources such as other pickups and control voltages (CVs).
