Guitar Worth Calculator

Wondering what your guitar could sell for? Our free guitar worth calculator gives you an instant used-market value range based on brand, era, and condition — no email, no signup. It's the fastest reality check before you list, trade, or insure an instrument. For a deeper dive into valuation, read the complete guide to how much your guitar is worth.

Authenticity Quick-Check

Buying used and wondering if it's the real thing? The free fake guitar quick-check walks you through the classic counterfeit red flags — price, seller behavior, serial, decals, and workmanship — and gives you an instant risk band for Fender, Gibson, Squier, Epiphone, or any other brand. If flags come up, the $9 Authenticity Checker screens the actual listing photos.

Factory Setup Specs Lookup

Skip the manual hunt — the factory setup specs lookup pulls the manufacturer's recommended action, relief, and pickup heights for your exact model. The perfect starting point before any DIY setup.

Action Height Calculator

Not sure what your string height should be? The action height calculator recommends target measurements at the 12th fret based on your guitar and playing style, so you can set up with confidence.

Action Measurement Converter

Already have a string-height reading? The free guitar action measurement converter converts millimetres, decimal inches and fractions such as 5/64. Its measurement guide explains how to compare the same string and fret before choosing an adjustment.

Pickup Height Calculator

Get the ideal pickup-to-string gap for your Strat, Tele, Jaguar, Jazzmaster, P-Bass or PRS, then a raise/lower recommendation from your current measurement with the pickup height calculator.

Guitar Intonation Checker

Open strings in tune, but fretted notes sound off? Use the free intonation checker with your tuner to compare pitches, find the next step for your bridge, and print a six-string checklist. Your readings stay in your browser.

Setup Calculator

Get your guitar's factory setup calculator specs — action height, neck relief, and pickup height — for your exact model in one snapshot.

String Gauge Recommendation Tool

Get a personalized string gauge suggestion — plus three string set picks — based on your guitar, playing style, genre, and tuning with the string gauge recommendation tool.

String Tension Comparison

Compare the same string at two scale lengths or tunings with the free string tension comparison. See the estimated percentage change before rechecking your setup; it does not calculate a replacement gauge or a safe tension limit.

String Comparison Tool

Compare popular string sets side by side — gauges, materials, feel, and tone — with our string comparison tool. Find the right set without buying five packs to try.

Acoustic Guitar Humidity Checker

Enter a case or room hygrometer reading in the free acoustic guitar humidity checker. Compare it with Taylor’s 45–55% reference range and find the next observation to make before changing your setup.

My Gear Garage

Keep your whole collection organized in one place. My Gear Garage tracks your guitars, maintenance schedules, and setup history so nothing falls through the cracks.

External Practice Resource: Chord Genome

Once your guitar feels comfortable to play, find a song to practise. Austin's Chord Genome song search lets you enter chords you know, such as G, C and D, and find songs that use them. It is an independent resource, separate from Owning A Fender. Free searches show a limited sample; an account or paid plan unlocks more results and features.
