The GMC of #stayhome

$2,100 for a custom copy*

It started in 1998

Not as a guitar. As a van. In 1998, I gave up my VW bus for a brand-new GMC Savanna with a diesel engine and an extended wheelbase. I was behind the wheel for almost every mile it traveled. The interior configurations changed over the years, but one thing never did: there was always a place to sleep inside. We put a lot of miles on that van. It carried the band, the gear, the luggage, and me all over the country. It was transportation, sleeping quarters, an equipment hauler, and an occasional home away from home. It went to gigs. It went cross-country. It accumulated stories. And eventually, it died.
Why Throw It Away? By the time the engine gave up, the GMC wasn’t worth much on the used-car market, but that didn’t mean it wasn’t worth anything to me. Then my dad said: “Why don’t we part it out?” That sounded like a good idea. It turned out to be a lot of work, but it also turned out to be a surprisingly good idea. I started selling the parts on eBay, one piece at a time. In the end, I made about five times more from the parts than I could ever have gotten from selling the entire van—even if someone had been willing to pay top dollar for a vehicle with a broken engine. So the GMC became my Boneyard, and I started looking at its parts differently.
The Moment. One day, while I was sorting through the parts in our backyard, I picked up the timing chain cover from the 6.5-liter diesel engine. For some reason, it felt like a guitar—not metaphorically, but actually felt like one. The shape, the weight, the openings, the mechanical history of it—it had already done a job, spending years as part of an engine that moved a van and a band all over the country. Now, it wanted to make music. You can see the TimingChain cover in the lower left of the photograph from that day. That was the beginning of TimingChainCover.
The Boneyard Rule became especially meaningful during #stayhome: Use what you already have. Don't shop for materials just because the original idea calls for them. No starting over because the piece in front of you isn’t conventional; look around, see what you’ve saved, and figure out what it might become. That is how a dead GMC became a guitar. The engine timing chain cover became both the body and the tailpiece, a Cherry carpenter’s level became the beam, a piece of spruce stair tread became trim, and violin parts and boat hardware found their way into the mix. The parts weren’t chosen because they belonged together; they belonged together because they were here. That distinction is important.
Sculpture That Happens to Play. TimingChainCover is classified as a Simple guitar, but there isn’t anything particularly simple about the story behind it. The body is essentially automotive sculpture. The maple neck has a rosewood fretboard and a 24.75-inch scale with 24 frets. A Tune-O-Matic bridge keeps things familiar where it matters, while a vintage chicken-head knob adds just the right amount of mechanical weirdness. The guitar has a humbucker and an AC-1 Rhythm VOX amplifier, powered by USB. The amp is small. The story isn’t.
From the Road to the Boneyard. This one has a nice symmetry: that GMC spent years carrying music around the country. When it could no longer do that job, I took it apart and sold the pieces to people who could use them, but one piece refused to stop traveling. The timing chain cover became a guitar. So instead of carrying the band to the gig, it became part of the gig. That’s what I like about the Boneyard. The objects don’t necessarily get preserved—they get reassigned. A guitar can become a guitar again, a broken instrument can become a neck, a carpenter’s level can become a structural beam, and a piece of a dead diesel engine can become the body and tailpiece of a musical instrument. Nothing has to remain what it was. It just has to be interesting enough to save.
The GMC of #stayhome. The Stay Home collection was built during a strange period when the world got smaller and time got bigger. I couldn’t go out and find whatever material I thought I needed, so I went through what I already had. In this case, that included the remains of a vehicle that had already carried me through years of traveling, playing music, sleeping on the road, and collecting stories. The GMC was finished. The guitar wasn’t. So I gave the GMC one more job. TimingChainCover is a piece of transportation history that learned how to play—the GMC of #stayhome.

#stayhome collection

*The Boneyard Rule

These twelve guitars are the surviving record of one very particular moment: March–June 2020, when the outside world stopped, and the Rubytone boneyard became the hardware store.
The listed collection price applies when you purchase the entire twelve-guitar collection together. You can buy individual guitars separately for an additional $1,000 per guitar.
Unless, of course, you would be happier with a copy.
That’s where things get interesting.
A Rubytone copy doesn’t have to be exact. It can be your version of the idea, built around what makes sense to you.
Choose your:

Neck • Beam • Bridge • Tailpiece • Tuners • Pickups • Controls • Colors

The original twelve were made from whatever was lying around in the boneyard.
Your Rubytone can start there—and go somewhere entirely different.

playing

Fun to Play
10
The first test is whether the guitar makes you want to keep playing it. A high score means the instrument feels inviting, responsive, and rewarding rather than merely interesting to look at. The best examples have enough soul that you forget you are evaluating them and simply keep going.
Playability
10
Measures how naturally the instrument responds to ordinary playing technique across the neck. Action, fretwork, neck feel, access, and setup should work together without asking the player to compensate for the design. A strong score means the unusual construction never becomes an excuse for compromised playing.
Ergonomics
10
Considers how comfortably the instrument sits against the body, hangs from a strap, and positions the hands. Weight distribution matters as much as total weight, especially when found objects or onboard amplification shift the center of gravity. The most artful solutions make an unconventional shape feel surprisingly natural.
Tone Quality
7
Judges the character, clarity, richness, and usefulness of the instrument’s core sound. The goal is not one supposedly perfect tone, but a voice with musical identity and enough detail to reward attentive playing. The highest scores go to guitars whose sound has real soul rather than merely acceptable frequency response.
Tonal Versatility
6
Measures how many genuinely useful sounds the instrument can produce rather than simply counting switches and settings. Different pickup combinations and controls should create musically distinct choices that a player would actually use. A clever circuit scores higher when its versatility feels purposeful instead of complicated for its own sake.
Amplification
6
Evaluates how convincingly the guitar performs through its intended amplification system, whether external or built in. Output, clarity, noise, feedback behavior, and usable volume all matter. For self-amplified Rubÿtones, a high score means the amplifier feels integrated into the instrument rather than attached as an afterthought.

build

Fit & Finish
10
Evaluates the precision and care visible in joints, edges, fretwork, hardware installation, surfaces, wiring, and final setup. Handmade character is welcome; carelessness is not the same thing as character. A strong score shows experienced workmanship while allowing the object to retain the marks and soul of its previous life.
Portability
4
Measures whether the instrument’s mass and dimensions make sense for the way it is meant to be used. A guitar with an onboard amp may reasonably weigh more, but every added ounce should earn its place. High scores reward designs that are easy to carry, hold, busk with, or live with without sacrificing the idea.
Reliability
10
Rates the likelihood that the guitar will keep working properly through normal playing, transport, and repeated use. Structural joints, wiring, controls, hardware, and power systems should feel dependable rather than experimental in the risky sense. A high score means the wit of the design is backed by experienced engineering.
Repairability
10
Considers how sensibly the instrument can be serviced when something eventually wears out or fails. Standard parts, accessible wiring, replaceable components, and understandable construction all help. The strongest designs are inventive without turning a future repair into an archaeological excavation.
Solutions
10
Scores the quality of the solutions used when unconventional materials create unconventional problems. Beam placement, neck angle, pickup clearance, feedback, balance, and internal packaging are all opportunities to demonstrate experience. High scores go to solutions that are technically sound and artful enough to look inevitable afterward.
Integration
10
Measures how successfully all the unrelated parts become one coherent working instrument. Neck, beam, body, hardware, electronics, amplifier, and found objects should cooperate mechanically and visually. The best integrations have a kind of soul: the parts stop looking assembled and start looking as though they found each other.

design

Innovation
10
Measures whether the guitar introduces a genuinely fresh idea, solution, relationship, or way of thinking about an instrument. Novelty alone is not enough; the innovation should improve the object, deepen the concept, or open a useful new possibility.
Shouldn’t Work
10
Rewards designs that appear improbable but succeed because the underlying engineering is sound. The wit comes from the gap between what your eyes expect and what your hands and ears discover.
Beauty
10
Judges visual appeal without assuming that beauty must mean polished, conventional, or expensive. Proportion, material, color, age, texture, and restraint can all create beauty in very different ways.
Sculpture
10
Considers the guitar as a three-dimensional object even when nobody is playing it. Silhouette, negative space, depth, structure, and the relationship between functional parts should reward viewing from more than one angle.
Coherence
10
Measures whether the many materials, colors, shapes, and components read as one intentional composition. A Rubÿtone can be busy, strange, or witty without looking accidental.
Relic
10
Rates the visual and emotional value of genuine age, wear, patina, scars, repairs, and evidence of earlier use. Authentic history carries more weight than artificially manufactured distress.

concept

Stage Presence
10
Measures how strongly the instrument communicates from across a room or under performance conditions. Silhouette, scale, color, movement, and unusual construction can all contribute before a note is heard.
Stands Alone
10
Judges whether the instrument feels complete and compelling without requiring a long explanation of why it matters. The story may deepen the experience, but the object should already make a persuasive case visually and musically.
Material Story
10
Considers how much meaning comes from the history and previous purpose of the materials themselves.
Transformation
10
Measures how completely the original object has been given a convincing second identity without erasing where it came from.
Boneyard Score
10
Rates how deeply the instrument embodies the practice of building from saved, secondhand, leftover, or previously overlooked materials.
Necessity
10
Asks whether each major component has a reason to be there. Extra hardware, controls, decorative pieces, and technology should contribute to function, story, balance, or visual composition.

personality

Story
10
Measures the strength of the narrative carried by the guitar’s materials, development, accidents, people, places, and decisions.
Surprise
10
Rates the number and quality of discoveries the instrument offers after the first glance.
Conversation
10
Measures how naturally the guitar makes people curious enough to ask questions.
Cool Factor
10
Captures the difficult-to-measure quality that makes an instrument desirable before every reason can be itemized.
Identity
10
Measures how immediately the guitar feels like itself rather than a variation of something more familiar.
Rubÿtone DNA
10
Rates how clearly the instrument expresses the recurring ideas behind Rubÿtone: reuse, structural invention, functional sculpture, irreverence, and serious playability.

impact

Humor
10
Measures whether the guitar contains genuine wit rather than a joke pasted onto an otherwise ordinary object.
Punchline
10
Judges whether the concept resolves into a satisfying final idea—the moment when the viewer suddenly understands why a particular object, material, or decision is there.
Disdain
10
Measures the willingness to question inherited rules about what an electric guitar is supposed to look like, contain, or be made from.
Rules
10
Rates how effectively the instrument departs from established guitar-building conventions while remaining musically and structurally convincing.
Copy Potential
10
Considers whether the central idea could inspire a new custom build without requiring an exact duplicate of the original.
Evolution
10
Measures how much useful creative territory remains in the idea after this particular guitar is finished.
