They sound phenomenal! The tone is amazing. I could not think of a better pickup for the Strandberg!!

Steven Ruiz


I know a guy who has the NUs and loves them. He is me. For all my gear head music type friends. Cycfi.com is designing and building some amazing open source hardware. […]

Quality for sure. My Nus are lovely, behave perfectly, sound clear and clean, and have impressed some impressive people.

Alan Pagliere


Joel, your Neo pickup has given me the edge. Am creating some mad sounds with it allowing me to stand out from the rest!

Jaydev Mistry


It’s a undeniable gear essential, every tonal range in the palm of your hand! Playing any other guitar/pick up after that experience is a loss! So versatile, from Jazz, Blues, Country, Rockabilly, Metal this is sure to please […] it’s spot on! Truly love this pick up system!

Matt Szlachta


By the way, I forgot the most important: the pickups sound incredible!!!! Can’t stop playing! Clarity, dynamic, warmth, articulation; I’m very pleased! 🙂

Pascal Vaucel


Seriously, they “Just worked” with the VG-99 and they sound FANTASTIC straight through amps.

Vance Galloway


That neck XR is just something else… the best pickup of all time as far as i’m concerned.

— No doubt about it, the XR and Nu are awesome bass pickups. The 6Appeal is amazing for bass as well. This guitar sounds huuge!

Dylan Reznick


The hardware for my new bass has just been finished and now I made some tests with the Nu and I am STUNNED! It has such a clear nice character to its sound, truely inspiring! Brilliant work!!

Joel de Guzman is the principal architect and engineer at Cycfi Research. He is a software engineer specialising in advanced C++ and an advocate of Open Source. He has authored a number of highly successful Open Source projects such as Boost.Spirit, Boost.Phoenix and Boost.Fusion. These libraries are all part of the Boost Libraries, a well respected, peer-reviewed, Open Source, collaborative development effort. The Boost Libraries are being used by organisations and companies all over the world from CERN to Adobe. There’s a big chance that the very computer you are using to read this now is using the Boost C++ Libraries.

Nu Polyphonic Pickup

Joel is an artist and a craftsman by heart and the C++ libraries he creates reflect this inherent artistic desire. He has been writing software since the mid-80s, but long before his first program, he was already into building electric guitars, amplifiers and effects processors. He has been building electric and electronic musical instruments and effects processors for more than 30 years now. In fact, it was his passion for music that led him to becoming a software developer in the first place. Almost immediately after teaching himself electronics, he began to realize that, slowly, software began encroaching into and somehow engulfing his world of music.

Fast forward 2014. The emerging Open Source hardware revolution became the perfect chance for Joel to unite music with his passion for both software and hardware. Joel is a DIY guy. He loves building stuff. In his early years as a musician, he got inspired by people like Craig Anderton, who wrote DIY electronics articles in magazines such as Guitar Player and Electronic Musician and Brian May who, together with his father, built a one-of-a-kind electric guitar which gave the band Queen its own unique sound. This same DIY culture fueled the rise of Open Source hardware. This is evident in the popularity of DIY sites such as Make, Hackaday, and Instructables. It’s with this philosophy that we approach design challenges to bring innovative products to market.
