It was just the "listener's ear"... pure anecdotal evidence, and that was good enough. High-end cable vendors made a lot of money on that perception.
Then someone came along recently and demonstrated, in a controlled test, that there is no difference between a thousand dollar cable and a length of coat hanger wire. Some of us (the skeptics in the crowd), were not all that surprised.
Is it the repetitious string plucking or the spirital act of music production? Who knew and who cared? Now we have someone who has applied a theory to the development of technology intended to simulate extensive playing time. Is this idea scientifically sound and can it be verified using technology? Who knows and who cares? The original idea that repeated playing improved an instrument's sound needed no scientific validation - just the listener's ear. Why is this no longer good enough?
Because we're human, and humans are fallible, emotional, and subject to confirmation bias.
We all want to believe our mandolins are getting better over time with constant playing. But without an objective test, there's no way to tell whether it's the mandolin getting better, or you getting better as a player, and learning how best to play that particular instrument. Throw in changes in string brands and picks as your tastes evolve, and the opportunity to hear and compare other instruments over time besides your own, and it gets even murkier. How well do you know that you're remembering, with perfect accuracy, what your mandolin sounded like when it was brand new? And were you the same player then (in terms of taste and experience) that you are now?
If just a few people would do the following demonstrations, we could stop arguing:
- Set up a test rig where the instrument is strummed with a mechanical gadget, to eliminate player variables.
- Record a new mandolin at a fixed mic distance (or an older one that needs "improving").
- Use whatever de-damping or vibration method you like.
- Make another recording with all settings exactly the same.
- Take both recordings, put them online, but don't identify which is which.
If there is a volume change, and if all the variables in the test have been carefully controlled, then that will be immediately obvious.
Then we test for tone improvement. If there was a volume enhancement, we zero out that difference to remove the well-known human bias in favor of volume, when comparing audio files. Now put the files online again, and don't identify which is which.
Can people hear a difference with those unmarked files? More importantly, what's the statistical breakdown? People might still hear a difference, but disagree on which file sounds "better."
Ideally we'd have several people contributing tests on different mandolins, so we could start to get a statistically meaningful (and repeatable) tests. Some instruments may respond to this better than others (or not at all). It would also be interesting to compare a test like this, with one where a mandolin is just played normally, off and on, for the same length of time. That could demonstrate that the method is useful for folks who don't play often, but maybe not worthwhile for those who play their instruments daily (that is, if the process works at all).
So that's the basic skeptic position on this. Show me that it works. And if it does something useful, show me that it's noticeably better than just playing the mandolin almost daily, like I'm doing now. Otherwise, why would I want to buy a gadget like this? What's the incentive? I'm a total gear-head (can 'ya tell from my posts here?!), but only when I know I'm getting something actually useful, and not snake oil.
