National
Since 1927
National's story spans nearly a century—from the original National String Instrument Corporation founded in 1927 by John Dopyera, to the modern National Reso-Phonic Guitars established in 1989 by Don Young and McGregor Gaines in San Luis Obispo, California. Dopyera's revolutionary tricone resonator design—three aluminum cones amplifying the guitar's sound mechanically—was 'The Greatest Musical Sensation of the Age' before electronic amplification existed. Today, National Reso-Phonic handcrafts resonator guitars in metal and wood bodies, producing over 300 instruments annually. These are the instruments of blues, bluegrass, and roots music—Dire Straits' 'Brothers in Arms' album cover features a National.

Complete National Guitar Guide
Comprehensive buying guide, price analysis, model comparisons, and expert insights to help you understand everything about National guitars.
National Price Overview
National covers a wide range of instruments from entry-level to professional models. Typical used prices vary by condition, series and year. Higher-end USA models and limited editions retain value better than mass-market lines, while rare or vintage pieces often command significant premiums.
When evaluating value, consider originality (pickups, hardware), structural condition (neck, frets, finish) and documentation (serials, receipts, setup reports). Price dispersion across platforms is common; local stores offer service and inspection, whereas online marketplaces provide broader selection and price transparency.
For detailed buying advice, model comparisons and condition-based pricing, read the full guide linked above.

National Timeline
Original National Founded
John Dopyera patented the tricone resonator design—three aluminum cones to mechanically amplify the guitar before electronic amplification existed.

Model-Specific Buying Guide
Each model has unique characteristics that affect both tone and value. Here's what to look for when buying specific models.
Tricone Guide
The Signature Sound
Tricones produce a smooth, choral tone with exceptional sustain—three aluminum cones creating harmonic complexity no electronics can replicate. At $2,800-$5,000, these are serious instruments for serious players
Material Matters
Steel bodies are darker and more immediate. German silver (nickel-silver) is brighter and more resonant. Brass sits between. Each material fundamentally changes the instrument's voice
Raw Series Patina
Raw Series tricones develop unique patina over time—each instrument ages differently based on the player's chemistry. Fingerprints become part of the guitar's character. A living instrument
Single-Cone Guide
Blues Machine
Single-cone biscuit-bridge Nationals are THE blues resonator sound—grittier, louder, more aggressive than tricones. Son House, Bukka White, and every delta bluesman's instrument
Wood vs Metal Body
Metal bodies (steel, brass) are louder and brighter. Wood bodies are warmer and more acoustic-sounding. For amplified blues, metal bodies cut through. For acoustic settings, wood bodies blend better
Slide Guitar Specialist
Nationals excel at slide guitar—the resonator's sustain and projection are perfectly suited to slide technique. Many players buy Nationals specifically for slide work
Used National Buying Guide
Handcrafted Retention
Handcrafted National Reso-Phonics hold value exceptionally well—used prices at 75-90% of new. The small annual production (300+) limits supply and supports strong resale
Cone Condition
The resonator cone is the heart of the instrument. Check for dents, warping, or rattles. A damaged cone dramatically affects tone and value. Replacement cones are available but affect originality
Vintage National Expertise
Pre-war National originals ($2,000-$15,000+) require expert authentication. The resonator guitar market has fewer fakes than standard guitars, but condition grading is critical at these prices
