How to Manage a Guitar Gear Inventory (and What to Actually Write Down)

The question comes back around on r/Guitar every few months, usually from someone who just bought their fourth or fifth guitar: what do you all actually use to keep track of this stuff? The replies are always the same. A spreadsheet somebody built in 2019 and abandoned. A notes app. A camera roll. One person swearing they remember everything, which holds up right until they're standing in a shop trying to recall whether the Tele already got locking tuners.

I keep an inventory for boring reasons. When a guitar gets stolen or a pipe bursts, the insurer wants proof you owned the thing. When you sell, the buyer wants specs and you want the price you paid. And when you sit down to a guitar you haven't touched in five weeks, it helps to know what gauge is on it and when those strings went on.

What to actually write down

Most people either record nothing or try to record everything and quit by the third guitar. The middle version has four layers, and only the first two matter on day one.

Start with identity: brand, model, year, color, and serial number. That's the layer a police report wants, and the layer anyone buying it from you later will ask about.

Then specs, which are the things you go looking for when you can't remember. Body and neck wood, fingerboard wood and radius, scale length, string count, the pickup in each position, bridge, tuners, nut material, and how many volume and tone knobs it has. They take ten minutes to look up once and then never change unless you mod the guitar.

The third layer is current state, and it's the one people skip. Tuning, string brand and gauge, when those strings went on, and any setup notes: action, relief, intonation quirks, the one fret that buzzes above the 12th. Six months later this is the only layer you actually wanted.

Last is provenance. Where you bought it, what you paid, and the receipt, with the receipt image somewhere you can find it in a panic.

Then photos. Take four per guitar: full front, full back, headstock with the serial legible, and a close shot of anything unusual like a repair, a mod, or a finish flaw. Do it in daylight against a plain wall and it takes two minutes.

Where people keep it, and how each one fails

There isn't a wrong answer here. The pattern I'd watch for is the one where the record and the photos live in different places, because that's the version nobody keeps current.

What the OpenFret version looks like

OpenFret's inventory is free and the fields are already built, which is the entire pitch. Each guitar takes brand, model, string count, scale length, body, neck, and fingerboard woods, inlay style, fingerboard radius, weight, the pickup in each position, bridge or tailpiece, tuners, nut, string set, tuning, finish color and type, case, country of origin, control layout, and where you bought it. Anything not in the dropdowns has an Other option where you type the real part name, and your typed name is what shows on the guitar afterward.

Two things it does that a spreadsheet won't. It logs string changes per guitar, so “when did I last restring the Les Paul” has an answer instead of a guess. And your practice sessions attach to a specific guitar, so after a few months you can see which one you actually play and which one is furniture. Each guitar can stay private or go public on the community page, and if you buy similar instruments you can save a template and reuse the spec block instead of retyping it.

What it doesn't do: there are no fields for serial number, purchase price, or a receipt upload, and it only tracks guitars, not pedals or amps. Which brings us to the next two sections.

Serial numbers, receipts, and insurance

Keep serials and receipts, but keep them somewhere private. Posting a serial number publicly is how people end up with a stranger's guitar being “verified” against their photos in a resale listing, and it does nothing for you. A password manager's secure notes, an encrypted folder, or a document shared only with your insurer all work.

If your collection is worth more than the contents limit on a standard renter's or homeowner's policy, ask about a scheduled personal property rider. Insurers usually want a description, a serial number, a purchase receipt or a recent appraisal, and photos. That list is exactly the inventory above, which is a good argument for doing it before you need it rather than the week after a break-in.

Pedals, amps, and the rest of the pile

Pedalboards move around more than guitars do, and most people track them worse. You don't need much: a photo of the board as currently wired, a list of what's on it with serials, and a note of which power supply outputs feed what. Do the same for amps, cabs, and interfaces. A single spreadsheet tab covers all of it, and the board photo alone will save you an hour the next time you tear it down for a gig.

The habit that keeps it current

Every inventory system in the world dies the same way: it's accurate on the day you built it and fiction six months later. Two rules fix that. Enter a new guitar the day it arrives, while you're still excited enough to type. And update the string line whenever you restring, because you already have the guitar on your lap and a fresh packet in your hand. Everything else can drift.

If you want the string half handled for you, log the change in your collection the moment you cut the old set off. And if you'd rather your practice time also left a record behind, the practice tracker and Guitar Quest both write to the same account, so the guitar with the most hours on it is a query rather than a feeling.
