FM16 Skervesen (Goliath)


This is the smallest and lightest of all the guitars. It’s a 16-string headless, multi-scaled guitar. The reason we made it multi-scaled (fanned frets) was to have an instrument that felt totally different from the others, so it would inspire me to write different music; if a guitar feels different, it inspires different music. I always wanted to have a headless guitar as well, so it would be easier to travel with. We wanted to make a 16-string guitar as light and small as we could. 


Skervesen: 16-string Headless (Goliath)

String Setup: 16-string (8+8)

Scale: Multi-scaled 25.5” / 27”

Pickups: Nazgul (Bridge) SH-6 (Neck) Seymour Duncan

Neck: 15 piece.


This guitar was inspired by the Gibson 335, and “Lucille” (BB-king’s guitar). This is a crossover between a traditional jazz guitar and a rock guitar. It includes an extended scale (26.5) 8-string guitar with high-gain Seymour Duncan pickups for rock/metal, on a traditional jazz body. The result is an

unparalleled sound for distorted, percussive techniques and big, 8-finger chords. This instrument’s clean tone is very suitable for soft chords, but somehow the lowest strings are so strong that they easily get distorted, allowing me to play really heavy percussion.

FM-5175 "Jazz/Metal"

This is a traditional jazz guitar, inspired by the famous Gibson L5, and ES- 335. We named it “Jazz Metal Guitar” because of a concept we developed that allows a traditional jazz guitar to keep it’s traditional sound, while being able to achieve huge amount of distortion for heavier sounds. The huge body provides a big, unique low end that I use mostly for 8 finger chords and really heavy percussion for heavy metal. This guitar also features the first- ever 8-string jazz pickups (SH2) made by Seymour Duncan. Out of all the guitars, this was the hardest to build.

FM-907 (Mastodon)


Biggest, most massive guitar of all. This guitar has the lowest notes possible, including a 9-string guitar on the lower side. We wanted to make a guitar with the most extended range possible for the technique, but that also would feel like a guitar rather than a bass. Since there is more wood on this guitar, the resonance is bigger, giving more body to the lower notes. We don’t consider this a “rock” guitar, rather than something standard for all styles. Also, the lowest string on this guitar its a 135, which is like the lowest string on a 6-string bass.


String Setup: 16-string (9+7) 

Scale: 27”

Pickups: EMG 907X 

Bridges and tuners: Hipshot.

Wood: insanely figured spalted Maple

Fingerboard Material: highly figured curly oak (VERY RARE STUFF)


This is another rock guitar, made with a body shape that allows it to be lighter, and gives it a unique “upright” position when played siting down. It is high-gain, and very dense. We used several layers of wood, to experiment with resonance from the instrument, and added a piezo pickup to make it sound acoustic when needed. 

FM-214 (Prototype)

String Setup: 14-string (7+7)

Scale Length: 25.5

Pickups: Seymour Duncan SH-2 Jazz (Neck) SH5 Duncan Custom (Bridge)


For this guitar, we wanted to experiment with several things. First and foremost, to make a 16-string guitar with a regular electric guitar shape that used active pickups and a 16-piece neck of several wood types. It wasn’t made to be played live, but rather, to see how a 16-string guitar with these characteristics would sound and feel. The result is a guitar with a massive sound, due to the amount of wood used. It’s mainly a rock guitar. We made


many guitars like this, some of which were not completed.

General notes:

-If you want to buy any of this guitars, send a message using the contact section of this website.

-All guitars are exactly like a regular electric guitar, only with another set of strings above the regular fretboard. 

-Most guitars have a stereo output (one fingerboard per output)

-These are the “featured” models. There are a few more models, but they were made just for experiments, so I prefer not to put those guitars here.

-I use standard tuning on all guitars. No exceptions.
