Hi, I am Joel de Guzman. I am a software engineer at BoostPro Computing specializing in advanced C++ and focused on the Boost libraries, a peer-reviewed, open source, collaborative development effort. I am an artist and a craftsman by heart and the C++ libraries I create reflect this inherent artistic desire.
These pages show the other side of me. I have been writing software since the mid 80s, but long before my first program, I got into building electric guitars, amplifiers and effects processors. I have been building electric/electronic musical instruments and effects processors for 30 years now. As much as I love software development, it is the passion for Music that has driven me to become a software developer. Almost immediately after teaching myself electronics, I began to realize that, slowly, software is encroaching into and somehow engulfing my world of Music.
Cycle of Fifths. A structure used by music theorists to depict the harmonic relationships among the twelve notes in the chromatic scale as a tool for composition.

where can i buy your stuff?
Hi Greg. It’s still in the R&D stage, but I do intend to go into production as soon as all the quirks are ironed out. I’ll keep you informed.
Hi Joel,
The Cycfi Alpha looks awesome. Any chance of doing an extended scale version or even a 7 string version of the guitar? When can we start putting down orders for the guitar?
Thanks for your interest! Going from prototype to production was not as easy as it seemed. Right now, I’m on gamma (from alpha and beta). I’ll keep you informed. Right now, I have a major backlog in documentation. There’s so much information I want to share.
Hi Joel,
I am a software developer too and I also share your love for coding and music. Please add me to your mail list, I would like to be informed when you go into production.
Thanks, Francisco. I’ll see what I can do.
