|Otto Link STM-NY and Timbre Trainer|
I settled on an Ottolink Super Tone Master New York Series. These mouthpieces are notoriously "hollow" sounding, like you are playing subtone all the time. That hollowness can sound uncentered or like it doesn't have enough core. I hoped that through using the device we could hear that element of the sound change so that the tone would sound more centered or have more color to it.
For the experiment I set aside two Rico Jazz Select Filed reeds and labeled them. I set up a controlled recording environment where I would be a consistent distance from my microphone, and I made sure the microphone's recording level was consistent. I recorded both reeds before I used the Timbre Trainer, and then I recorded both reeds again afterwards.
There was one hick up in the process. I was planning on using the device for around 100 hours, like I did in my test last year. However, the device stopped working entirely sometime between 20-25 hours. I'm not sure what is wrong with it or if it's repairable. It just stopped working, and that is after approximately 120-125 hours of use total over the time I've owned it (maybe there is a warranty?). Anyways, I only ran the device for 20-25 hours on this mouthpiece, so whatever changes we hear in the after clips most likely would have been increased if I kept running the device.

What I Hear
To my ears, there is no contest between "Reed 1 Before" and "Reed 1 After". Clearly, "Reed 1 After" has more core and a richer sound. It also sounds cleaner.
In terms of richness of sound and core, the "Reed 2 After" clip also beats out "Reed 2 Before". This is in spite of an interesting development in how the reed played. When I recorded the before clips, reed 1 felt much softer than reed 2. Reed 2 also felt a bit stuffy, and both it's hardness and slight stuffiness come across in the before recording. Interestingly, when I recorded the after clips the reeds had switched and now the reed 2 felt softer than reed 1 and softer than when I originally recorded the before clip with it. It still felt slightly stuffy however. Despite the softening of reed 2, the "Reed 2 After" clip still has a noticeably richer sound and more core compared to the hollower "Reed 2 Before" clip.
Overall, I'd confidently say there is a marked improvement in how the mouthpiece sounds. I'd also say that the experience of playing the mouthpiece after the trainer is more enjoyable than before. This is likely simply due to the improved timbral quality, making the tone easier to hear and more beautiful to listen to.
Should you go buy one? Maybe. It is possible we are actually seeing some of the physical process behind why vintage instruments generally play or sound "better" to most musically mature ears. If you're playing vintage equipment, I probably wouldn't mess around with Timbre Trainer. However if you're playing on a modern setup that you wish had a richer sound, then go practice. ; ) If after years of practicing you still want a richer sound, this is possibly one way of modifying your sound.
This was only my first test on modern equipment (and my device broke), so I can't endorse it with 100% confidence. Certainly, this is one direction that will hopefully investigated further in the future.
