Ibanez S670QM Review


The time of the mid-priced metal machine has returned! In this Ibanez S670QM review we’re going to take a look at it’s features, tone and practicality. Ibanez has made some bold choices with this guitar. Let’s find out if they paid off.

Overview of Ibanez S670QM

One of the reasons the S670QM is cheaper is because it’s produced in Indonesia. That cuts labor costs, but there are potentially a few areas where they’ve cut costs on components too. 

The S670QM is a full scale guitar at 25.5″. It features a mahogany body with a quilted maple top, which accentuates the finish. Despite the body being predominantly mahogany, the S670QM is exceptionally light. The neck is made from 3 pieces of maple, which makes it much more durable and resistant to warping than the single piece necks found in other guitars. 


The neck profile is Wizard 3. It’s not quite as flat as some of the other Wizard profiles and it’s quite thick. It seems to be a stalwart of the mid-priced guitars that Ibanez produces. The fingerboard is made from Jatoba, which is an interesting choice.


Jatoba has been employed as a sustainable alternative to Rosewood, so there’s not really much affect on the tone. My reservation is the aesthetic. For me the guitar would look much better with a stained fingerboard. Perhaps that’s just personal preference, but the color of the fingerboard seems to contrast too harshly with the rest of the guitar’s design. Ibanez is now making a Rosewood variety from 2021, which looks much more stylish!

Key frets are marked out by offset white dot inlays. Again, perhaps these should be black to contrast better with the light colored fingerboard. There are 24 jumbo frets, so plenty of room for maneuver. The jumbo frets will make playing feel more slick and allow you to pull off some pretty extreme string bends. Things that will appeal to the metal guitarist. 

There’s a locking barless nut, which gives you tuning stability even when hammering the Tremolo to perform dive-bombs! Speaking of Tremolo, the bridge is an Edge Zero 2 style, which gives you a Tremolo arm, but tightens everything up. Another feature that’s a nod to metal guitarists. 



A set of standard Ibanez tuning machines sits on the sharply styled headstock. These will do the job and combined with the locking nut you should get decent tuning stability.  Coming back to the headstock, the body color is carried through to the headstock. The quilted maple almost gives it a flaming quality. 

The guitar comes with a set of .009’s. They’re not bad, but you’ll want to swap them out to your favored brand and gauge. The S670QM comes in two colors, Dragon Eye Burst and Sapphire Blue.


The S670QM comes with two humbucker style pickups and one single coil. The pickups are super high output, so will handle heavier styles well. In terms of their quality? They’re nothing to write home about. The two humbuckers are passive / ceramic, which is ok. Clearly the guitar would be much better with a set of active pickups. The single coil is passive Alnico. Pretty standard for a guitar in this price range. 

There’s a five way pickup selector switch that enables you to find a range of pickup combinations:

  • Position 1 – Bridge humbucker
  • Position 2 – Bridge & Middle
  • Position 3 – Middle
  • Position 4 – Middle & Neck
  • Position 5 – Neck humbucker

There’s a couple of control knobs too, one for master tone and another for master volume, so you don’t have fine control over individual pickup’s tone. The hardware is finished in black, which I think gives a nice contrast to the color of the guitar. 


As you’d expect, this guitar is set up for heavier styles such as metal. The super high output pickups are at home with heavier styles. Even at the neck position, where you’d expect a little more crunch, it’s still trying to tear your face off. 

But there’s more to this guitar than just metal. When played clean it has a really nice chimey sound to it. The neck position is actually really good for blues, jazz and funk. But you might look a little out of place playing this guitar at a jazz club!

The bridge and middle positions are really good for most styles, but I can pickup that classic clean Metallica sound really easily. Again that’s probably to be expected as this really is a metal machine!

Final Thoughts

The S670QM is the next step up from the Ibanez RG421, however for an extra $200 I can really only see that you get an additional single coil pickup. The problem with Ibanez guitars is that there’s not much between the roughly $600 S670QM and the pricier Prestige models that are around $1,500. 

That might be where it’s worth looking at a Jackson or a Schecter for something at the mid range with a little more punch. I really like how light weight this guitar is, and with the inclusion of Rosewood fingerboards from 2021 they’re getting their styling back on track. 

It’s a practical guitar. It’ll play heavier styles well. The fingerboard is slick, even if the neck could be a little thinner. Although the two humbuckers do their job adequately, swapping them out for a set of active pickups will make the guitar better.
