COLT Duo Acoustic End-button 90º
FASTER COLT DUO – Acoustic End-Button – Cello, has been developed from the FASTER PRO violin model and adapted to the acoustic characteristics of the cello. It features an elaborate, compact, and complex design that enhances the cello’s sound and tonal quality, combined with increased harmonics and improved acoustic emission.
By incorporating two specific silver tubes with internal compressors, the FASTER COLT DUO eliminates the residual air generated inside the cello’s soundboard, which limits its vibration capacity. It reproduces the vibrations of the lower area of the cello’s soundboard and other adjacent parts, generating a significant amount of acoustic power and contributing to the growth of harmonics, which are reinforced by increasing the intensity of the emerging air collected by the two silver tubes.
FASTER COLT DUO substantially inhibits vibration dispersion. works on the cello as an “all-in-one”:
- Enhances radiated energy.
- Amplifies sound production and acoustic projection.
- Distributes and organizes the frequency spectrum.
- Offers high acoustic stability under pressure and humidity variations.
- Increases harmonic production.
- Expands dynamic range.
- Increases timbre quality.
- Facilitates playing.
- Increases response speed.
- Reduces, in most cases, the production of wolf tones.
- Eliminates, in specific cases, the production of wolf tones.
- Prevents the loss of a large portion of the acoustic energy produced by the cello as well as the transfer of unwanted frequencies.
- Transmits the recovered energy, acting as a passive amplifier.
The COLT DUO is the ideal complement to the FASTER Artica, Dorna, and Meiga acoustic end pins for cello, as well as the BELTON acoustic stoppers. The combination of these elements undoubtedly offers an abundant amount of quality sound and great playability.
When you need to install your COLT DUO on a different cello, simply purchase a replacement COLT Cone, adapt it to the new instrument, and attach your COLT DUO

TECHNICAL CHARACTERISTICS
- End-Button with a single size, suitable for any 10 mm diameter cello end pin.
- Weight: ± 63gr.
- Measurements and t: 3.5 x 3 x17cm.
- Offers great comfort and precision in opening and closing, exerting a high degree of coupling force with approximately half a turn of the tightening knob.
- Simple assembly system using an easily adaptable universal cone (from ∅ 28 to 25 mm) machined from insulating thermoplastic resin.
- Dynamic interior blocking system against parasitic vibrations, made of elastic polymer with maximum mechanical resistance.
- End-Button made of composite with high dimensional stability, excellent hardness, and density that favors the speed of sound propagation. This material offers high resistance to traction, deformation, and wear due to friction.
- Two 935 silver tubes, 8.4 and 9.9 cm respectively, and 7 mm in diameter, with brass and silver compressors.

The Faster Titanium is incredible. The violin has been reborn in a whole new dimension. It is the best acoustic invention in the history of the violin.
Congratulations!

I have used FASTER Titanium in my Oddone violin since its assemblage in London. The violin sounds very well, is freer, and has a quicker response thanks to an increase in harmonics.
It is undoubtedly an excellent tool for those seeking to enhance the qualities of their instrument, and for that, I recommend it!

The FASTER Titanium belongs to the trained ear seeking out the precise balance between string pressure and freedom of sound. A unique tool in service of expressivity.

I have installed many FASTER devices, and the result is outstanding.
Acoustic volume and ease of playing have increased to a great extent in all cases.
If you want to equip your instrument with a turbo, I recommend it to everyone, both musicians and luthiers.

Of the present plethora of acoustic cello endpins, the FASTER Artica Titanium stands out to a notably large extent. It is the result of years of research and experience by maestro luthier José María Lozano, and, like FASTER for violin and viola, enhances both the quality and the quantity of sound in a truly astonishing manner. That happens both from the player and the listener’s perspectives. However, if I had to choose only one out of the multiple advantages it contributes, that would probably be its outstanding feeling of convenience. That is noticeable in the immediate reaction of the string in contact with the bow, and the left-hand’s smoothness of articulation. That not only produces better acoustics-related results but also, thanks to that feeling of convenience, gets to increase the cellist confidence in their instrument and themselves. Not everyone can afford a Strad; however, a big step is within everyone’s reach with FASTER. In my opinion, it instantly gets to turn a cello into a better one without spending a fortune.
Maestro Lozano and his FASTER succeed in making us happier by substantially improving our experience with the instrument.

I have installed the FASTER Titanium by maestro Lozano in my J. B. Vuillaume violin, and I am well satisfied with the surprising effect.
The sound is more bright, open, and rich in harmonics. The response of the strings during a bow stroke is much quicker. The instrument is undoubtedly more comfortable to use, and besides, the wolf tone that it had on the fourth string is practically gone.
I strongly recommend FASTER to everyone wishing to enjoy their instrument’s potential to the fullest.

Following the tests carried out in Cezzane Recording Studios, aimed to check the empirical result and potential advantages of the mechanical device called FASTER for violin, I have observed that the device has real effectiveness in the instrument tone.
My perception as a sound engineer and producer of many chamber music and orchestra recordings that include the violin as a soloist instrument is that, with FASTER, the sound is louder and more broadly spread. Besides, those notes that, due to the instrument’s characteristics, were excessively loud, are now balanced, and the listener perceives a more steady and silky sound. After recordings of the same length of time, I have also noticed that, with the FASTER device, the microphones have captured an extra richness in harmonics and sound frequencies, because, far from changing the timbre of the violin, it enriches its sound and therefore the music coming out of it.

Dear José María, I wish to share with you the satisfaction I feel to play my Mario Capicchioni viola with the FASTER Titanium on it.
The sound, which was already good before, has utterly improved in quality and power, with many more harmonics. The sound of the instrument has gained bright and timbre sweetness, thanks to the sound range amplitude.
I appreciate your great work very much. My most sincere congratulations!
With affection and admiration,
