Re: Another Reason Compensated Claw is a MYTH
Lew, guitar playing is very much about feel, no question. Some people string up with bridge cables and rock out. Others need dental floss.
David, in the 20th century, science made significant advances in guitar building, in what was up to then an artisan-driven craft.
Both ideas and points of view have equal merit.
The guitar player uses the tools literally at hand, to the utmost expression of their art.
The guitar builder takes pride in creating their best effort, for a legacy of quality and durability.
Referee calls a draw. No winner, no loser, no rematch.
Let's chill for a minute, then.
Again I ask, how can we test something with so many variables?
We can measure, evaluate, and correlate 'til the cows come home, but what specific item or items, or set of materials, conditions and settings, will yield the postulated theorem most consistently?
Perhaps most importantly, how can we account for playing technique idiosyncrasies, in the margin of error?
What would the A/B/X be in a true double- or triple-blind test? How would any possible placebo effect be counteracted and accounted for?
TLDR -- It's a university-level engineering project, people. Who's gonna pony up the bucks?
Until then, this is nothing but a p***ing contest.
While I admire your efforts toward diplomacy, I do not see this an argument of equal and opposing opinions, but debate over a phenomenon with one, factual, definitive answer. I'm not discussing what feels best, what avenue of setup procedure works best for different tinkerers, or what is perceived to have a better tone.
One simple question.
Does changing the lateral distribution of tension on the back of a tremolo block affect a difference in relative pitch changes between strings when you pull the tremolo back?
Much as I love diplomacy, this is an impersonal fact, a right or wrong answer to a simple singular question which keeps getting lost in a cloud of peripheral issues and distractions.
It doesn't take much. This question is not complicated, does not include many variables (only one actually, which is the point of doing such a test to appraise influence if singular factors), and is not terribly difficult to test. Take your guitar and adjust the trem claw at the opposite angle with the same float (use something like the G raising a minor third with the trem full back as a reference). Will the B and E be end up sharper or flatter at full back than they were with the opposite trem claw angle? Do the test yourself, and you'll see it doesn't make a difference.
For those seeking advice on setting up their trems, this alteration does not affect any real change in how the strings change pitch relative to one another.
On a separate note (important, this is
separate from the primary issue in discussion), this did pique my interest in effect on feel and stiffness with different spring adjustments. I did set up a Strat trem with the claw at a maximum angle (3 springs), claw straight, and then claw straight with 5 springs, and measured the force at a marked point at the tip of the bar required to lower the third string 1 full step. It was a quick cursory test, not as tightly controlled as I would call ideal, but I did find the angled claw to require about 2-4% greater force, and the 5 spring of course much more at about +22% compared to the straight claw 3-spring.
So yes, angling the claw does appear to stiffen up the trem a bit compared to straight (but less than adding additional springs). So the feel can be a bit different, tuning stability during a bend and how far you have to bend a string to hit a target can all be affected. Of course I checked the tuning while I was doing this, and when you pull from neutral back to the deck, each string sharpens by the same amount whether angling the claw treble back, bass back, straight, or 5 springs. No surprise of course, as the strings are still being extended and stretched the same amount in each case.
Still, it was good to do the test myself just to reassure myself that the laws of physics hadn't changed on me recently. I was getting worried for a minute.
