The Ibanez S670QM is a mid-range superstrat that pairs a slim S-series body with a quilted maple top, offering a clear visual upgrade over plain finishes and a tonal brightness that complements modern pickups.
This review breaks down what the model name means, the specs to verify, how it sounds across genres, and practical buying and setup advice you can use right away.
Why the Ibanez S670QM Catches Players’ Attention
The quilted maple finish immediately lifts perceived value. Figured tops like quilted maple provide a three-dimensional look under gloss that plain solid colors can’t match, and buyers often equate that visual appeal with higher build quality.
Beyond looks, a figured top can add a touch of brightness and upper-mid shimmer, especially over a mahogany or basswood body, which influences tonal balance without overwhelming pickup character.
The S-series identity is clear: a thin, lightweight superstrat body aimed at speed and comfort. These guitars suit shredders who need fast necks, session players who need versatile tones, and giggers who value low weight and quick attack.
Headline selling points to expect in an S670QM overview are: playability from a slim neck, tonal versatility from flexible pickup configurations and switching, and a mid-range price-to-performance that competes well with S570 and S770 siblings.
What the Model Name Actually Tells You (Decoding S670QM)
S = S-series style: thin S-body, ergonomic contours, and a focus on speed. 670 = the model tier within that series, placing it above entry GIO models but below Prestige in finish and hardware. QM = quilted maple top, indicating the figured top wood and a higher-grade finish option.
That breakdown implies typical specs: contoured maple or mahogany top pairing, good mid-range hardware, and better finishing than base models. Expect several model variants and SKU differences across finish options and production years collectors note.
Production years matter. Different runs may use slightly different pickups or bridges. Check model variants, SKU, finish options and serials when comparing listings.
Full-Spec Checklist: What to Confirm When Researching S670QM Specs
Body woods — confirm whether the body is mahogany, basswood, or alder beneath the quilted top. Body wood affects weight and midrange character.
Top wood — quilted maple top is the S670QM marker. Look for a genuine figured top rather than a veneer if you care about visual depth and resale value.
Neck construction — bolt-on vs. set neck changes attack and sustain. S-series usually uses bolt-on or a secure joint optimized for speed.
Fretboard material — rosewood, maple, or ebony influence feel and brightness. Ebony and maple are snappier; rosewood is warmer.
Scale length — usually 25.5″ on S-series. Scale affects tension and string feel for bends and drop tunings.
Frets — confirm fret count (often 24) and size. More frets extend range, fret size changes playability and bending comfort.
Pickup configuration — check if it’s HSH, HH, or HSS. That determines tonal range and available wiring options like coil-splitting.
Bridge type — floating tremolo vs. fixed hardtail affects tuning stability and sustain. Note the exact bridge model for replacement parts and setup tips.
Why each spec matters: tonewoods shape resonance and sustain; neck joints affect attack and access; pickups and wiring define the palette of clean to high-gain sounds.
Trusted sources for official specs include the Ibanez site, dealer listings, and factory spec sheet; use serial lookup tools and the Ibanez specs sheet to confirm production details.
Visual and Build Details to Inspect in Photos or Stores
Look for consistent grain matching on the quilted maple and a smooth, even clear coat that brings out the figured top without orange peel or dust nibs.
Check binding lines and headstock logo for even application. Uneven binding or a misaligned logo are signs of rushed production or prior damage.
Inspect fretwork closely: leveled frets, smooth fret ends, and no gaps between fretboard and frets. Fret buzz often starts with poor fret edges or crown wear.
Cosmetic red flags: finish bubbles, uneven binding, missing headstock tuners, hardware corrosion, and mismatched screw heads. Any of these can signal poor care or a refinished top.
Pickups and Electronics: How the S670QM Shapes Its Voice
S-series guitars commonly ship in HSH, HH, or HSS layouts. Humbuckers give thicker high-gain tones; single-coils add clarity and chime. HSH setups offer maximum versatility for gigging players.
Quantum pickups appear in many Ibanez models; they lean toward modern clarity and high output. Coil-splitting on humbuckers widens the sonic options, offering single-coil-like tones for cleaner parts.
Expect standard wiring with a five-way or push-pull coil-split option on many S670QM variants. That translates to practical tones for blues, pop, and metal without swapping pickups.
Testing tips: check neck-to-bridge balance, probe the noise floor for hum, and cycle pots and selector to feel for scratchiness. Noise or intermittent signal often hides behind dirty pots or loose solder joints.
Neck, Frets, and Playability: Why the S670QM Feels Fast
The S-series favors slim neck profiles. Look for profiles close to a Wizard neck or a thin U profile with a flatter radius for fast fretting and easier legato runs.
Radius and fret size impact speed. A flatter radius allows lower action and faster runs; medium-jumbo frets help bends without choking notes on the fretting hand.
Evaluate fretwork, action range, and how the guitar handles bends and vibrato. Good setup will show consistent action across the neck, minimal dead frets, and accurate intonation.
Setup targets: for a 9–46 gauge set, aim for 1.5–2.2 mm action at the 12th fret on the low E and 1.2–1.8 mm on the high E with slight relief for clean bends. Adjust intonation after string gauge changes.
Bridge Hardware and Tuning Stability: Tremolo Options and Setup Realities
S-series bridges vary from fulcrum-style floating tremolos to fixed hardtails. Floating tremolos provide dive-bombs and expressive motion; they need careful setup to return-to-pitch reliably.
Test tremolo performance in-store: perform a full dive and check return-to-pitch, listen for binding at nut or saddles, and test spring tension feel. Ask the seller about previous tremolo setups and spring replacements.
Maintenance notes: lubricate contact points at the nut and saddles, tweak spring tension to match playing style, and consider locking tuners if you push heavy trem use. Major adjustments may need a pro for stable setups.
Tone in the Real World: Demos, Genres, and Amp/FX Pairings
Practical tone snapshots: expect clean chime from single-coil splits, crunchy rhythm from bridge humbuckers, and singing high-gain lead tones that cut with a tight low end on a boosted amp.
Suggested pairings: a transparent tube amp or a neutral solid-state head plus an overdrive for midrange push; add delay and reverb for lead layering and a boost for solos. Use EQ to tame any upper-mid harshness from the quilted top brightness.
When evaluating demo videos, watch for heavily processed tracks. Prefer dry mic or DI clips that show raw pickup character and check for consistency across neck and bridge positions.
Compare-and-Contrast: S670QM vs Other Ibanez Models and Similar Guitars
Against S570 and S770: S670QM typically sits between them in finish and hardware quality. The S770 may push closer to Prestige-level components; S570 is more budget-focused.
Compared to the Prestige line: Prestige models offer finer fretwork, upgraded pickups, and tighter quality control. The S670QM trades some of that polish for a lower price while keeping key S-series playability.
Competitors — Jackson, Fender-style superstrats, and Epiphone/PRS intermediate models — will each favor different neck feels and tonal signatures. S670QM often wins on weight, figured-top visual appeal, and price-to-performance.
Buying decision matrix: choose S670QM if you want a fast neck, quilted top aesthetics, and flexible tones at a reasonable budget; pick Prestige or higher if you need top-tier hardware and finish.
Real-World Buying Guide: New vs Used, Price Ranges, and Negotiation Points
Expect new MSRPs to sit in the mid-range Ibanez bracket; used Ibanez S670QM price depends heavily on finish condition and whether the quilted top is original or refinished. In the secondhand market, figured tops command a premium.
Inspect used units for neck straightness, fret wear, electronics operation, headstock cracks, repaired tops, and serial number consistency. These checks reveal hidden repair costs and authenticity issues.
Negotiation points include visible wear, non-original hardware, and service history. Ask about warranty transfers, refurbished units, and dealer return policies before buying.
Smart Upgrades and Mods That Give the Biggest Payoff
High-impact swaps: replace pickups with voiced neck and bridge humbuckers for clearer definition and more bite; upgrade tuners and the nut for better tuning stability. These deliver measurable tonal and playability gains.
Low-effort mods: a professional setup, fret dressing, higher-quality strings, and cavity shielding for reduced interference. These are affordable and often produce the biggest immediate improvement.
Avoid heavy mods on collectible runs or limited production finishes, as modifications can reduce resale value and complicate authenticity checks.
Maintenance, Setup Checklist, and Longevity Tips for S670QM Owners
Routine care: wipe down after play, condition the fretboard with a light oil twice a year, tighten hardware, and check intonation and action monthly if you gig regularly.
Seasonal prep: keep the guitar in a stable humidity environment to protect the quilted maple top; use a case humidifier in dry climates and avoid leaving the guitar in hot cars or direct sun.
When to book a pro: fret leveling, major neck shims, complex electronics work, or structural repairs. DIY is fine for truss rod tweaks and basic intonation, but leave major surgery to a luthier.
Accessories, Cases, and Gigging Considerations Specifically for S-Series Guitars
Protection: a hard case is recommended for quilted maple finishes to avoid dings and temperature swings; a padded gig bag can work for short local gigs with extra care.
Useful accessories: strap locks to prevent drops, quality cables for noise-free signal, a case humidifier for maple tops, and preferred string brands in 9–11 gauge depending on play style.
Practical gigging tips: carry spare springs, a backup set of strings, a small toolkit, and a compact tuner. Keep a clipped-on cloth for quick wipe-downs between sets.
Troubleshooting Common S670QM Issues and Quick Fixes
Fret buzz: check for low action, uneven frets, or excessive relief. Start by adjusting truss rod a quarter-turn at a time or raise action slightly before assuming fretwork is needed.
Dead frets: local high frets or loose fret ends often cause dead notes; minor fret dressing can fix this, but significant cases need a tech.
Pickup hum: test single-coil splits for noise; cavity shielding or a proper ground can often cure hum. Check solder joints before replacing pickups.
Bridge slipping or tuning drift: lubricate pivot points, check spring tension, and inspect the nut slots for binding. Locking nuts and tuners help for heavy trem use.
