Best Resonator Guitars — Dobro & Resophonic Guitar Buying Guide
A resonator guitar uses a spun metal cone (or three smaller cones) instead of a wood soundboard to amplify string vibration — producing a distinctive loud, penetrating, metallic tone that cuts through acoustic environments without amplification.
Resonators come in two main formats: round neck (played like a standard guitar, common in blues) and square neck (laid flat on the lap, played with a bar, common in country/bluegrass dobro style).
Round-Neck vs Square-Neck Resonator
| Type | Playing Position | Style | Tuning |
|---|---|---|---|
| Round neck | Standard guitar position | Blues, country blues | Standard or open G/D |
| Square neck | Horizontal on lap | Bluegrass, country dobro | Open G typically |
Most electric blues players (and those wanting one resonator that does both) choose round neck. Bluegrass players typically choose square neck dobro.
Best Resonator Guitars
Recording King RR-36 — £400 | Best Budget Round-Neck Resonator
Round-neck, mahogany body, spider-bridge biscuit cone (single cone), nickel hardware. The RR-36 is the most recommended entry resonator guitar — genuine slide tone, solid build quality, and realistic price.
Best for: Blues slide guitar, country blues, beginner resonator players wanting a round-neck.
Gretsch G9200 Boxcar — £350 | Best Very Budget
Round neck, all-laminate mahogany, spider bridge, brown sunburst finish. Gretsch's entry-level resonator — functional and good value, though the laminate construction limits long-term tone development.
vs Recording King RR-36: The RR-36 has better tone and build quality at similar price. The Gretsch suits players on the tightest budget.
Gretsch G9240 Alligator — £550 | Best Mid-Range Square Neck
Square-neck dobro, mahogany body, Fishman pickup, single-cone spider bridge. The G9240 is the most popular mid-range dobro — the Fishman pickup makes it suitable for live performance with a PA system.
Best for: Bluegrass dobro players who perform live.
National Style O — £1,200 | Best Professional Round-Neck
Single-cone resonator with biscuit bridge, all-metal body (brass or steel options), engraved body artwork. National invented the resonator guitar in 1927 — the Style O is the historic original used by Tampa Red, Son House, and Bukka White.
Metal body vs wood body: Metal bodies produce brighter, louder, more cutting tone — the National sound. Wood bodies (Recording King, Gretsch) are warmer and more acoustic in character.
Best for: Professional blues players, recording artists, collectors.
Resonator Tone: What to Expect
Resonator guitars produce a loud, bright, metallic tone with pronounced attack and immediate decay. They are loud enough to cut through acoustic ensemble playing without amplification — a key advantage for acoustic blues and bluegrass.
With a slide or bottleneck: the resonator's sustain and harmonic response make it ideal for slide guitar. The metallic tone projects through acoustic environments better than standard acoustic guitars.
Round Neck vs Square Neck Is the Decision, Not Price
Before comparing specific resonator models, the round-neck versus square-neck decision determines almost everything else about how you'll actually play the instrument — playing position, technique, and genre association are all downstream of this single choice, far more than which specific brand or price tier you select.
Committing to a format based on genre first, then choosing a model within that format, avoids the common mistake of buying based on price or looks alone and discovering afterward that the playing position doesn't suit your intended style.
Common Mistakes
Buying a square-neck dobro for blues slide playing. As the Round-Neck vs Square-Neck table shows, round-neck resonators suit standard guitar-position blues playing, while square-neck dobros are laid flat on the lap for bluegrass-style technique — these aren't interchangeable playing positions.
Choosing a metal-body resonator expecting warmth over projection. As the National Style O entry explains, metal bodies produce brighter, louder, more cutting tone specifically — players who want warmer, more acoustic character should look at wood-body options like the Recording King or Gretsch instead.
Assuming all "budget" resonators deliver similar value. As the guide's direct comparison notes, the Gretsch G9200 Boxcar suits only the tightest budget specifically because the Recording King RR-36 offers meaningfully better tone and build quality at a similar price point.
Overlooking that resonator tone genuinely changes slide technique requirements. The instrument's loud, bright, immediate-decay character interacts differently with slide playing than a standard acoustic — worth understanding before assuming existing slide technique transfers directly.
ToneStakr's Take
For most blues and country-blues players wanting one versatile resonator, the round-neck Recording King RR-36 remains the sensible default — genuine slide tone and solid construction at a realistic price, without the compromise of the Gretsch's laminate-only construction. Bluegrass players should commit to the square-neck Gretsch G9240 Alligator specifically for its Fishman pickup and live-performance suitability, rather than trying to make a round-neck resonator serve a fundamentally different playing position.
Frequently Asked Questions
What is the best resonator guitar?
The Recording King RR-36 (£400) for the best value round-neck resonator. The National Style O (£1,200) for professional-grade round-neck tone and historic authenticity. The Gretsch G9240 (£550) for dobro-style square-neck playing.
What is the difference between a dobro and a resonator?
"Dobro" is a brand name, now owned by Gibson/Dunlop, commonly used to describe square-neck resonators played horizontally in bluegrass style. All dobros are resonators, but not all resonators are dobros — round-neck resonators represent the blues-style format instead.
What tuning do resonator guitars use?
Open G (D-G-D-G-B-D) is the most common resonator tuning across both formats. Standard tuning also works well for round-neck resonators specifically. Square-neck dobros almost always use open G given their lap-style playing technique.
Can a round-neck resonator be played with a slide the same way as a standard acoustic?
Largely yes, with adaptation — the technique transfers reasonably well, though the resonator's brighter, more immediate-decay tone response means slide players often adjust their touch and vibrato slightly compared to a standard wood-top acoustic.
Is the metal-body National Style O worth the price jump for a non-professional player?
For players specifically chasing the authentic vintage National brightness and projection heard on historic blues recordings, yes — for players who mainly want a functional, good-sounding resonator without that specific historic tonal signature, the wood-body Recording King delivers excellent value at a fraction of the cost.
Do resonator guitars require different maintenance than standard acoustics?
Somewhat — the metal cone assembly (spider bridge or biscuit bridge) can loosen or need adjustment over time in ways a standard acoustic bridge doesn't, so periodic inspection of the cone seating is a maintenance step specific to resonators.
