guitar.services · about this directory
One guitarist’s work, indexed in one place.
guitar.services is a directory, not a publication. It links to everything Jason Colapietro has published about guitar: two books, an engineering-grade signal chain reference, chord and scale libraries, and the tools built on top of them. There is one address to remember instead of six.
What’s here
The home page lists every surface: the two books, the guide library, the chord and scale references, Strumly, and the iOS app. Each entry links straight to that surface. This domain does not duplicate the content itself.
Four reference pages go one level deeper, summarizing rather than copying: The Signal Chain contents page summarizes the book part by part from its Strumly listing, the signal chain guides page sums up each guide and links its full text, the chord and scale library indexes every chord and scale on guitarchords.info, and the practice tools page lists the coach, tuners, trainers, and lessons.
The long-form technical writing (signal topology, gain staging, cable capacitance, pedalboard order, impedance, power and noise) now lives in Strumly’s guide index, grouped alongside practice-methodology guides and rights & IP guides for working musicians. That index is the closest thing to a “categories” page: guides are grouped by topic (Practice, Engineering, Rights & IP) rather than split across separate pages.
FAQ about guitar.services
Is guitar.services free?
The signal chain guides, the chord and scale references, and Strumly’s practice toolkit (tuner, metronome, ear training) are free to use. The two books are separate paid publications, sold through their own retail listings. This directory points to them.
Who writes the guides?
Jason Colapietro, founder of Suede AI. He is a self-taught guitarist and the author of both books linked from this page; the guides are his writing, not aggregated or crowdsourced.
How is this directory curated?
By hand. The list of surfaces on the home page is maintained directly by Jason as new guitar work ships. There is no submission form, no ads, and no third-party listings.
Where did the engineering-grade signal chain guides go?
They used to live at guides.guitar.solutions. They have since moved into Strumly’s guide library at strumly.suedeai.ai/guides, alongside practice-methodology and rights & IP guides, so the long-form guitar writing lives in one place. guides.guitar.solutions now redirects there. The Signal Chain, the book, also started at guitar.solutions; its listing is now at strumly.suedeai.ai/book.
What is the difference between guitar.solutions and guitar.services?
guitar.solutions is where The Signal Chain and the engineering-grade reference started; both now live inside Strumly, and the book’s listing is at strumly.suedeai.ai/book. guitar.services is this directory: a home page linking every surface Jason has published, four reference pages that summarize the book’s contents, the signal chain guides, the chord and scale library, and the practice tools, and this about page.
Is guitar.services affiliated with Suede AI?
Yes. guitar.services is Jason Colapietro’s personal guitar directory, and Suede AI is the company he founded that builds Strumly, Suede Guitar Tuner & Studio, and Suede Social.
Do I need an account to read the guides?
No. The guides are plain reference pages, with no login required. Strumly’s practice streak and rig builder need no sign-up either: the streak is tracked on your device, and the rig saves in your browser.
