About Flatter
A New Dimension of Sound - No Strings Attached
Flatter is a revolutionary, snap-on mod that transforms your regular guitar or bass into a fretless
instrument - without changing a single thing about your instrument. No tools, no damage, no
commitment. Just expressive freedom in minutes.
Version 2 of Flatter is the result of real-world feedback from players around the globe. We listened
carefully, refined every detail, and expanded the lineup to offer even greater compatibility,
playability, and sound.
Why Go Fretless? Why Go Flatter?
Fretless guitars and basses unlock a world of tone that fretted instruments can't reach - microtones,
glides, smooth vibrato, expressive slides, and unique harmonic textures. But fretless instruments are
rare, expensive, and often require irreversible modifications.
Flatter changes that.
With just a 2-minute installation, you can access the expressive beauty of a fretless instrument -
using the guitar or bass you already own and love.
What's New in Flatter V2?
We've taken everything that made the original Flatter special and made it better:
Four Guitar Models for perfect fit:
- Fender-style electrics
- Gibson-style
- PRS-style
- Classical guitars (52mm nut)
Two Bass Models for improved fit and tone:
- One for narrow-neck 4-string basses (~1.5" nut)
- One for wider-neck 4-string basses (up to 42mm nut)
*(Note: Not compatible with 5-string or short-scale basses)*
- Improved fit and feel based on player feedback
- Slimmer, sleeker profile
- Expanded fingerboard coverage
- Works with left-handed instruments too
- Optional rubber width adjusters for fine tuning fit
Effortless, Reversible, Reliable
Flatter installs in under 2 minutes - no tools, no glue, no screws.
It's made of ultra-clear, scratch-resistant polycarbonate, precision-cut to preserve your tone while
revealing the frets underneath, so you can see where you are at all times.
This makes intonation more accurate than traditional fretless instruments, especially for beginners.
The Origin of Flatter - By Gershon Waiserfirer
My musical journey started early - piano, then wind instruments, then strings. But it was the Oud that
opened my ears to the soul of fretless playing. The ability to bend notes, slide between them, and
explore microtonal nuance changed everything for me.
When I tried to find a fretless electric guitar, I hit a wall. So I did what any obsessed musician might
do - I ripped the frets off a regular guitar. The process was frustrating, expensive, and irreversible. I
thought: There has to be a better way.
That thought became a mission.After two years of prototyping and refining, Flatter V1 was born - a clear, functional, portable solution. And then, thanks to feedback from players worldwide, we made it even better.
Now, with Flatter V2, you can transform nearly any standard guitar or 4-string bass into a fretless
instrument. No risk, no tools, and no limits.
Flatter is not just a tool - it's a gateway to a whole new vocabulary of sound.
Whether you're into Middle Eastern maqams, ambient textures, cinematic swells, jazz phrasing, or
just curious about fretless exploration - Flatter gives you the freedom to experiment without
switching instruments or breaking the bank.
My hope is that Flatter helps musicians around the world unlock their own sound, their own path,
and their own voice - one slide, one bend, one note at a time.
