Maton EM425C/12, 12 String Acoustic Guitar - Review and Description

Maton EM425C/12
12 String Acoustic Guitar

A popular and solid 12 string Maton guitar, made last and sound good. Now a good mid-price 12 string option and great value in a studio for those times when you really just need a 12 string guitar.

The Maton EM425C/12, 12 String Acoustic Guitar was introduced in 1989 and was still in production in 2014 (possibly later). A popular 12 string offering from Maton, that was heralded as being amongst the last of the walnut back and sides guitars to be made by Maton due a shortage of suitable walnut timbers.

I had been looking for an upgrade to my trusty old Yamaha FG-410-12A for some time, but was not really keen on spending up to AUD $3K+ on a new Maton SRS Solid Road Series 12 string (or similar), when I don't really use a 12 string all that much. So I began looking into used 12 string guitar availability, in and around the AUD $1.5K mark. Other contenders included Takamine (who have a history of making some lovely 12 string guitars) and Taylor.

The guitar under review (purchased by the first and former owner in 2012) came with a Maton hard case. The instrument arrived in flawless condition, not a single scratch or mark. I take my hat off the the previous owner for his diligent care and maintenance of this fine instrument. Sadly the action was absolutely horrible. My first inclination was to look for the truss rod nut to see what size Allen key (Hex key) I needed.

Then, when I looked at the strings on the guitar, I immediately guessed they might be contributing to the problem. A set of 013-052 medium gauge strings (what I generally refer to as fencing wire). On a twelve string, that's a lot of tension.

Note: It wasn't until later that I discovered these strings actually come fitted as standard!

A few sets of D'Addario EJ41 12-String Phosphor Bronze 009-045 were ordered immediately.

The guitar under review (2012 vintage) was up for grabs on the bay of 'e' at AUD $1,200 (ONOOr Nearest Offer) ... and already had three offers. So rather than mess around, I put my money on the table and purchased it at the full asking price, which did include shipping and slightly damaged Maton hard case (missing bottom latch).

While encountering a new Maton EM425C/12, 12 string acoustic guitar is somewhat unlikely these days, I think I came pretty close. Since the EM425C/12 has been superseded by the more expensive SRS series, an older Maton model could be a very good purchase, if like me, you only occasionally use a twelve string.

Playing the Maton EM425C/12

To say that the Maton EM425C/12 12 string acoustic/electric guitar was challenging to play with even medium gauge strings is being unduly polite. The guitar comes ex-factory with 013-052 ('medium') strings fitted.

I'm just not a brute force kind of guitarist. So this review is based on the Maton EM425C/12 after being restrung with extra light 009-045 strings.

  About String Gauges, click to expand
Just FYI: There has always been, an often irrational debate, over 'light vs heavy' gauge guitar strings and which are the better. The only meaningful answer is of course, whatever works for you. Different playing applications and styles often require different strings - Dang! Who would have guessed?

Nobody sets out to make strings that sound like vibrating crap (except perhaps the Chinese, trust me, I've tried some of their strings ;-) ... However, if you are the curious type, there is a YouTube video you should see, that delves into string gauge tonality. I found it to be quite educational - it's based on electric guitar strings, but I think the fundamentals are generally valid and possibly not what one would expect ;-)

This is another vid I found later using an acoustic instrument, which essentially reveals a similar trend to the previous video. Listening to these on my Eris E5 Studio Monitors - to my ears, the heavier strings are duller, lacking both brightness and definition.

My sincere thanks and compliments to those involved for taking the time to do the subject some justice, without resorting to the often quoted and generally meaningless 'esoteric bullshit' that seems to pervade discussions on string gauge.

Having never encountered a twelve string guitar that was actually easy to play, and only ever coming close after tweaking my old Yamaha's action to the max, even the existence of an extra light gauge (009-045) set of strings for a twelve string was nothing short of a revelation.

However, in this case, while the lighter gauge strings definitely made the EM425C/12 easier to play, there was no significant improvement in the guitar's action.

Closer inspection revealed that the action was actually too high at both the Nut and Saddle - something I honestly had not expected, because that means it left the factory that way. Not at all a good look, Maton.

A few hours later - after - taking the strings partially off, to establish that the socket I needed was 8mm on a 70mm extension. Untangling (I think this is a ritual requirement), then restringing, then applying adjustments, tweaking the the truss rod several times (clockwise and about a quarter of a turn all up) - done! The action is as good as it is going to get, short of a full neck job.

The result - infinitely better, actually a pleasure to play now. With the action where it should be, the lighter strings make a big difference. Even a quick lick or two is no problem now. Chords at the 12th fret are a piece of cake.

Worth noting: The cutaway on Maton acoustic guitars, while not dramatic, is actually quite useful. Probably a little less so on a twelve string, where the increased action height (even with adjustments) around the twelfth fret will have most players avoiding that area.

If soloing or chording around the twelfth fret is not your thing, then it's worth considering the
(E)M245/12 non-cutaway version, which will have slightly greater loudness and depth of tone by virtue of the extra internal volume.

And lastly, it is interesting to note that there are other mentions on the internet of this Maton model that were, and I quote, 'a bugger to play'. Which suggests that the action problems I encountered might not be an isolated incident.

Measurements are provided with the Maton EM425C/12 specifications below.

Maton EM425C/12 Sound

With the original well worn (perhaps ancient) set of 013-052 Cleartone strings, there was nothing at all special about the sound. Though it was still brighter than my Yamaha FG-410-12A (the guitar I'm replacing).

With a new set of strings however, this beast sings like an angel ... OK ... you're right, I've never actually heard an angel. It sounds really good!

There is an actual harmonic sparkle to the sound with all twelve strings ringing, along with a beautiful clarity. This no doubt results largely from the Sitka Spruce solid top.

I was expecting more depth and bass, for a 'D' sized instrument. The overall general tone is definitely on the brighter end of the spectrum, both electrically and acoustically. Of course a substantial component of this new 'zing' will be the D'Addario strings.

Build Quality / Workmanship / Reliability (7/10)

Maton EM425C/12 internal view - Mostly nice and clean, rough in a few places.

The Maton EM425C/12 under review is a well made 'D' sized instrument, roughly about years old Calculated using Javascript. The previous owner looked after this guitar and kept it in superb cosmetic condition. The guitar could have come out of the shop last week. So reliability (and former owner) gets top marks almost by default.

Structurally everything on this guitar was 100% functional. An endoscopic inspection (above pic) shows that even the internal workmanship and attention to detail are good (as one should expect from Maton). The frets were beautifully finished, no sharp edges anywhere.

While technically not a fault, I did find the internal geometry and access to the truss rod to be somewhat less than optimal. It is very difficult to adjust the truss rod in a conventional manner while the EM425C/12 is strung without using a special Maton truss rod tool. Essentially a shaft that enters through bottom strap pin then extends through the guitar to the neck where the truss rod bolt is located.

Adjusting the Action on the Maton EM425C/12
It's a normal (not Hex) bolt that requires an 8mm socket, with a 80mm extension (minimum) on a small ratchet. Prying the D and G string sets apart will allow you to get the ratchet into position. A ratchet will allow incremental adjustments (clockwise to tighten / pull back / flatten the neck, viewed from the bridge end) without having to continually reposition the socket.
Warning - do this wrong and you could wreck the guitar.

Aside from the horrible action, this guitar has few flaws. The high, (almost unusable) action was a real disappointment when I realised it had probably left the factory that way. It can take quite a bit of tweaking to get a six string guitar set up right, so having to properly set up a twelve string instrument was just a total pain in the asp. No $2K instrument should leave the shop in that condition.

Active Electronics
I used to think that the AP4 pickup on my Maton EM125C was, well, unimpressive. And that I should have replaced it with an AP5 when I first got that guitar. I'm now glad that I didn't waste my money on such a 'not so little' upgrade.

Why would anyone build active electronics into an acoustic guitar and not include a tuner?

So yes, the AP5 does a job. It is clean, and quiet. The AP5 still uses two AA batteries and therefor still has f-all output, just like the AP4. The mid frequency can however be swept, which is actually a tangible improvement. Apparently the last models in the 400 series did leave the factory with the AP5 Pro electronics. I couldn't tell you whether that's a meaningful improvement.

Strings for the Maton EM425C/12

My general personal preference for guitars that are played regularly, are the light gauge D'Addario EJ41 Phosphor Bronze series strings. Nice and bright but can also deliver a rich tone. They do oxidise fairly quickly, but I'm prepared to put up with some dark smudges on my finger tips to get the sound that I want.

Instruments that are played less often, particularly 12 stringed guitars, may benefit from the coated and 'long life' strings available that are made specifically to NOT oxidise. Well not as quickly anyway. Thereby also keeping their tone a little better, for longer. This comes, of course, at generally double the cost of standard string sets.

Also beware when using coated strings that, while your strings may still look all nice and shiny, their tone may be long gone after a year or two under tension on a guitar

Also - It can be worth shelling out for a multi-pack purchase, which can bring the unit price down by anywhere from a third to half.

In this case the 009-045 EJ41 set was chosen in part to take some pressure off the neck - which just FYI, didn't seem to make any difference (which is good, because it indicates there are no truss-rod or neck issues). These will be the lightest strings I have ever run on a twelve string ... so watch this space [ ... ] ... no! I'm just kidding, there's no telling how long it could me to write more stuff here ;-)

(Only a week or two later) ... So, have you been watching?

It turns out that the finest/thinest string in the 009-042 set is not (as I expected) the pair of .009" high E strings. It is in fact, the .008" +octave G String. As I discovered after concluding that the strings could use a little more stretching, and then over-doing the same ... and breaking it ;-)   It broke at the tuning peg and it is unlikely that it would have let go just from normal playing. Another trade-off when using lighter gauge strings.

Just FYI - I'm replacing it with a .009, which I have plenty of, rather than breaking up a 12 string set, just for one string. Now added to my 'list of things to remember ... and not do'.

Value for Money (7/10)

Relatively speaking, the 400 series, Maton EM425C/12 was not as expensive as the current SRS series guitars. Though I have not seen it specified officially, the walnut back and sides are suggested to be laminated (plywood in the old lingo), by several reviewers. None the less, Maton's prices appear to have increased rather dramatically in the last few years, possibly due to a move to solid timbers all round. Most 'serious' manufacturers have had to go that way.

I hope that has also translated into a pay rise for the workers at Maton ;-)

While a recent series of upgrades have resulted in several new instrument purchases, on other occasions I have found myself balking at the price of some new instruments, and instead opting for a well maintained used instrument. That was the case with the EM425C/12. With the Maton SRS-70C-12 seemingly over-priced, a used Maton 12 string was a great option. I would have purchased (and reviewed ;-) a used and slightly more expensive SRS70/12 some months ago, had I been a smidge quicker on the draw.

Production of the Maton EM425C/12 began in 1989 and has now been superseded by the SRS-70C-12 (Solid Road Series). The Maton Museum is somewhat incomplete with respect to details on the Maton EM425C/12, but I have seen used ones for sale with manufacturing dates as late as 2014. There isn't as yet, a clearly specified production end date.

As a used instrument, if in good condition, these an are ideal option for the casual 12-stringer. There are other, similar (and sometimes cheaper) offerings from Takamine and Taylor that are also very nice instruments and worth a look. If you need to play a 12 string a lot, you'll probably get yourself an Maton SRS 12 string or perhaps go for broke and get a Martin.

Repairs, Parts, Restoration

Maton should be able to provide most, if not all parts should something need replacing. Which, I have to say, is unlikely unless the instrument has had a disastrous accident. For example, the machine heads are Grover. Whilst they could get banged up and damaged, they are unlikely to fail from normal usage over the life of the instrument.

Probably the biggest hazard is leaving some batteries in too long and having them leak and corrode some electronics. A relatively straight forward replacement job, if you have the skills and tools ... and possibly an opportunity for an upgrade ;-)

Earlier models of the Maton EM425C/12 had a bone Nut and Saddle, with ABS plastic Bridge Pins. Later models used a Black glass filled Nylon Nut and Saddle with white ABS Bridge Pins. These components should be readily available from the Maton web site or elsewhere online.

Should replacements be required, my personal inclination would be to either go back to a bone Nut and Saddle combo or perhaps try for a Tusq Nut and compensated Graphtech Saddle, if you wanted to go hi-tech (assumes correctly sized parts are available).

Determining the age of a Maton Acoustic Guitar:

On the inside label, the manufacture date comes after the serial number on guitars made up to 2015, where a date of (04/12) would equate to 'April 2012'.

An online App is apparently in production to assist with getting a manufacturing date for Maton guitars. For further information, please contact Maton (not this web site).


One of the interesting things about this purchase was relearning the importance of having a point of reference. It is a lot easier to decide how good or not an instrument is, when there is another instrument on hand for a direct comparison. While Maton make excellent instruments, so do many other makers these days ... and more to the point, so have guitar makers in the past ... some less well known.

In this case it was interesting to note that the Maton EM425C/12 was noticeably brighter in tone than the Yamaha FG-410-12A, even with substantially heavier gauge strings than the Yamaha.

  About my Maton Guitars - Click to expand
It was never my intention to collect Maton guitars, but I do now own 3 of them:

  •  MS500 Mastersound (Electric m.07/1999 - purchased new)

  •  EM125C (Acoustic Electric m.06/1998 - purchased new)

  •  EM425/12 (Acoustic Electric 12 String m.04/2012 - purchased used 2021).

While I do believe in supporting a local industry, and strongly advocate the avoidance of things 'Made in China', I have acquired and kept my Maton guitars because they are all durable, high quality instruments. Suitable for professional and enthusiast alike, these are instruments you can be proud to own - for a very long time.
