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 Artica Titanium Cello Endpin, designed and constructed by José María Lozano, has utterly outstanding features.
My first impression was the ease of sound production (strings vibrate unrestrainedly), and the spectacular sound quality. That is because of a tangible increase in harmonics produced by the cello, which undoubtedly gains volume and brightness in its sound, both in low and high ranges.
Never before had I come across an endpin that could improve the sound parameters of an instrument.
May my testimonial persuade other cellists to acquire one of these magical endpins. I herein thank maestro luthier Lozano, who passionate towards and skillful with nowadays technology, contributes to improving the sound of instruments existing for over three centuries, proving that the past and the future can work in harmony.

Maestro José María Lozano has got to revolutionize sound with his innovating FASTER system of endpins and stoppers, not just by boosting it up, but also by improving its quality, reaching levels of excellence.

I was introduced to the FASTER world by Giovanni Fabris, the concertmaster of our orchestra. I must say that, as soon as we fitted it to the instrument, I noticed an immediate change. The A string became sweeter, and the C string had a fuller sound. The instrument’s response is generally better in all positions.
However, the FASTER Titanium makes a real difference when you want to play piano and pianissimo because the strings, especially the low ones, go into vibration much easier. All my fellow players who have tried it are just as happy.
Thank you very much for this invention.

Bravo, José María! I never thought that the FASTER Artica 600 Titanium cello endpin could change, free, and project the sound of a cello to such a large extent.
You made it! Congratulations!

It is an outstanding contribution to the world of the double bass. After having tried the FASTER endpins and BELTON stoppers by José María Lozano in various concert halls and auditoriums, the summing-up cannot be better.
The sound quality improves by optimizing the harmonics as well as their projection. My feeling is that of more comfort at playing, which strengthens my self-confidence.
Congratulations!

Artica 500 Titanium cello endpin by maestro José María Lozano has increased the resonance and harmonics in my double bass. The sound spreads itself more naturally, and playing feels easier. Bravo!

I am very impressed with the possibilities offered by every endpin model!
I am particularly fond of the Artica 600 Titanium, which I installed in my modern 2001 Alberto Giordano violoncello. The A-string is now much softer and uniform as to the whole set, which makes me so happy!
Besides, the overall sound production of the instrument is smoother, and the noise in sound production has decreased. Also, the cello tone has improved in quality as well as loudness.
The instrument is now more harmonious and sounds better in practice.
Thank you very much for your valuable work.

Dear José María, the products of FASTER Sound Systems are amazing. The output delivered by your endpins and stoppers goes beyond reality. They are fantastic.
Never had I tried something similar, something that facilitated me to play freely, with no tensions, and with a significant increase in harmonics, loudness, and sound projection across the hall.
Thank you very much for your splendid innovations.
