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.

I have installed the FASTER Titanium in three violins that date from 1663, 1850, and 2012. Thanks to this great invention, the sound qualities have improved in all of these instruments.
FASTER inspires me and helps me do more with less.

Dear José María, thank you for the FASTER Titanium for my Stradivari violin.
It is a cool invention!

I am delighted with my new FASTER Artica titanium cello endpin and with the Belton Grafit cello end pin stopper. I feel how the vibrations of my instrument have increased in contact with my body, with the ground and around it. The harmonics have increased notably and my cello has a greater projection without losing its usual warmth, transmitting a round, clean and enveloping sound.

Dear friends and colleagues,
The first time they told me about Master Lozano’s FASTER Titanium, I was quite skeptical and incredulous. Now it is installed on two of my violins, one old and one modern. The change with the FASTER has been incredible with no less than 30% sound, projection, harmonics, tonal richness, and great playability.
José María I’m super happy with your genius . Thank you, thank you, thank you!.

Dear Maestro, I wanted to tell you that Professor Fabbris had already put the Faster on my “Augusto Pollastri” from 1925 with excellent results!
Then after I had my Cremona luthier do the work of closing and reopening the button hole (because it was too big), he finally inserted the Faster into my second instrument as well (a 1917 “Serafino Casini” published in the book “La Grande Liuteria Italiana” by A.Versari), obtaining a much more homogeneous and powerful sound for this instrument too!
Thank you again for your wonderful invention and for your great work.

I have been pleasantly surprised by the FASTER Silver. My violin sounds clearly cleaner and rounder, and I find it much easier to play. I can achieve the same effects as before with much less effort, and it helps me find greater sonic freedom. In addition, the harmonics sound clearer, which translates into greater projection. A great discovery!

My first meeting with Mr. Jose Maria Lozano was a unique experience in the best possible way. He opened me the door to the world of new sound options and I believe this is only the first step in the search for an amazing sound quality.
I can only recommend his FASTER Sound Systems for violin, so please try it and let yourself begin a new journey with your instrument. Sincerely,

Silvina Álvarez
Principal violist – Orquesta Nacional de España - Madrid
My experience with the Viola FASTER Titanium is always highly satisfactory.
I consider that the gain in resonance, in tone, in volume, harmonics and consistency in the sound, makes it an absolutely innovative accessory and to take into account when setting up an instrument, of course by the hand of a master luthier of the quality of José María Lozano.
