Testimonials & Performance

"I now like the sound enhancement so much that I almost always use it, even when I don't need to! Simply put, every cellist should own one."

"The super pin sounds so wonderful that I can't play my old pin anymore!"

" I can’t believe how the sound of my instrument has opened up – especially on the lower 2 strings. The tone color is so rich now, both under my ear and out in the hall."

"I wish to thank the cellist Jason Leopard and the channel Higher Hz for their efforts and giving me more exposure through his YouTube channel.  You can see his videos at:
Cello Practice: Tom DeVuono Endpin - YouTube
Cello Lessons: Acoustic Coupling Disc - YouTube"

" ...I haven’t regretted it since, virtually every aspect of sound quality from projection, resonance, response, and timbre have drastically improved."

"I was so pleased with the results of switching to the Tone Acoustics endpin, I decided to see if Tom’s rock stop could enhance the sound of my cello even more. The answer was YES! The rock stop added a more round and focused sound to the instrument. Now, when I play, I have the feeling that the cello has more power to give -- I can feel more layers are added to the sound. The rock stop produces more overtones to my ear, and works particularly well in a room-like setting. For those who have auditions for schools or professional auditions, this rock stop can give one that extra edge to the sound of your cello."

" ...It has not only enhanced the sound of my instrument twofold , but it has made playing the instrument easier and more responsive."

"These endpins are a game changer. I can't say enough positive things about them"

"The Tone Acoustics' endpin is the most innovative and important advancement in sound quality for cello and bass that I have seen - or heard - in decades. "

"I don't know if it's the design, materials, or mass, but the Tone Acoustics Endpin audibly improves the clarity and response of my 1765 Balestrieri. I love how it feels, and I'm never going back!"

"The bottom line is that I highly recommend this endpin! Awesome product!!"

"The Tone Acoustics pin gives me the widest range of color with very little effort."

"I am really happy that I invested in this pin. It has already been worth the price"

"I considered the custom endpin so important to my sound that I purchased a second one when I acquired another cello"

"It is as if I purchased a superior cello. My wolf tone is gone, the volume of my cello is louder, but projects better than before during soft passages, the sound is clearer, I am able to hear more overtones, and the cello responds faster. Thank you so much!"

" I can walk into any venue with the confidence that the disk will stay securely in place and give my cello its best sound"
