String gauges? 

The guitars come with Ernie Ball on the following gauges: .008, .011, .014, .022, .030, .038 (the blue package) and then .060 (7th), .074 (8th). If you want us to use 09 gauge, let us know. We suggest keeping the same gauges for 7th and 8th string. 



They are very light, almost like a Less Paul or a bass. We learned through years of experience to perfectly balance weight, tone and ergonomics. 


Neck wood options? 

Mahogany and maple.


Scale lengths? 

These are our favorite scale lenght for a well balance instrument for tapping, etc: 


Single Scale

6 & 7-strings: 25.5 

8-string: 27

9-string: 28



6 string: 24.75 - 25.5 

7 string: 25.5 - 26.5 

8-string: 25.5 - 27

9-string: 26 - 28


Multi-piece neck? 

Yes. We will decide that for you depending on the guitar /  bass model. 



Gloss, satin, or open pore finishes on ash body. 



Quilted maple, flame maple, spalted maple and burl maple. That's aside from solid colors, sparkle, relic, etc. 


Body options?

Mahogany, alder, and basswood.


Fretboard wood options?

Ebony or Jatoba. Ebony is a black/dark wood and Jatoba is almost orange / light rosewood looking.


What colors are possible? 

Pretty much any color is possible. 


Why headless? 

Lighter and more portable. It does not affect tone.


Will you guys be at the NAMM show 2021?



Why the guitars are so affordable for what they are? 

As of right now, we just want you guys to play them, they will get more expensive soon. 


What guitar pickups do you use?

We use our own pickups. They are voiced for tapping and works great for other techniques. They are mid gain and we use ceramic magnets. You can watch demos on the video section. You could also tell us if you want lower output on the pickups or a specific DC resistance. (we suggest we should that for you)


Can I use other pickups?

We can also use other brands like Bare Knuckle, Fishman, Seymour Duncan and Lundgren. To calculate the price, simply add the price of the pickups to the base price.  


What bass pickups do you use? 

Same as story as the guitar pickups. We have all styles available. 


Whats the size of these guitars? 

They are very small. The goal is to use as little wood as possible. The fit on most guitar cases. 


Why two fretboards? 

To expand the possibilities of the electric guitar. 


Scale Length?

Anything is possible, but we recommend 25.5, 26.5 and 27. 


Carbon fiber rods? 

Yes, 4. 


Are the FM muting strips included? 

Yes (they mute the open strings) 


What kind of hardware do you use? 

We use our own hardware. Mostly hipshot and tan bridges for tuners. 


Fanned frets / Multiscale?

Yes. Any scale is possible. 


Body size? 

Just like a regular guitar. Maybe even smaller. 


Average weight?

Depends on the model, but about 7lbs for the 12-string (less than a Strat!)


What is the middle wood strip in the front of the neck?  

That's actually the neck. We usually like to use two fingerboards, this way we use individual ratios for each neck. We can also make flat ratios. 


How do you call this type of guitars?

We call them by the number of strings since it's one neck. 12, 14, 16-string guitar. Or 8, 10 or 12-string Bass. You can also call them FM Guitar, FM Guitars, FM Bass and FM Basses. This is just not the name of the brand, it's the name of the actual guitar style we created. 


Copyright, trademark, patent?

Yes. Please don't allow other companies to make our guitars. 


Can I have a smaller symbols on the fretboards?

Yes. You can have the 1 fret size logo on the 12th fret. Just let us know on the specs. Guitar normally come with the bigger (3 fret) logo. You can also choose no logos. 


Will I get free photography and videography services if I own a FM Guitar?

Yes if you are in LA and are very talented.


Fanned frets vs normal frets?

Both work great. We recommend starting with regular frets although tapping is not harder using fanned frets. 


How much are these guitars? 

Refer to the pricing section. 


Do you have any instructional videos?

Check out the Musical Concept section on our website. More coming soon.


Who makes these guitars?

Each guitar is made by Felix Martin in collaboration with several luthiers around the world depending on the model and options. 


Who does quality control of the guitars?

Felix Martin. 


Left handed possible? 

Yes. In fact, Felix can make a video with it before shipping it! 


What strings are you using?

Ernie Ball. Common gauges 08, 09 and 10. It depends on the player. We use Ernie Ball 08 string set, with 66 and 75 for the 7th and 8th strings. 


Differences between ebony and jatoba fretboards?

They have a very similar sound on our guitars. Ebony is black, and jatoba are a bit more orange / dark orange depending on the kind of jatoba we get. 


Can you do with headstock instead of headless?

We only make headless as of 2022. 


Is it hard to play these guitars?

No. Fingerstyle is harder! 


Do they fit on most cases / gig bags? 

Yes. Remember the body is probably smaller than the guitar you already have. You should be able to find a case easily at guitar center, amazon, etc. 


Can you make the guitars with no logos?

Yes. Leave us a note. 


I'm endorsed by another guitar company, should I be using your guitars? 

Since these are a different type of guitars, they don't serve as a competition for other brands. It won't be a problem for them. Plus, we are good friends with most guitar brands in the business.  



The standard output is a mono jack (just like a regular guitar) but we can also use a stereo (TRS) jack for individual outputs and total separation between the two fretboards.


The guitars come with mono jack so you don't have to tell us anything. This is the most common setup. Felix (for example) uses mono/regular jack.


If you choose TRS, let us know. You would a "Stereo to Dual mono" or TRS cable. You can use an adapter as well on your TRS cable in case you want to use it as mono. All Felix guitars (before 2016) were in TRS. 


We can also use two mono outputs. 


Why the name FM Guitars? 

f minor chord.


Chapman stick / warr guitar? 

Those are not guitars / basses. Those are called "touch style” instruments. They have different specifications. The FM guitars are just like a standard guitar or bass, except they're ergonomically designed for tapping.


Double fretboard vs double neck? 

These guitars are designed to allow for tapping as well as traditional guitar techniques. Double neck guitars are made for a different purpose altogether, and they are very large and heavy. Additionally, the majority of these guitars have a 6-string and a 12-string neck. They are not designed with tapping in mind. 


Are your guitars double neck?

No. They are single neck.
