Yes to tune the WHOLE string length to the same pitch. To tune 2 strings of different lengths to the same pitch, you need different tensions. But you're not doing that. The only thing that control the pitch is the saddle-nut distance, string mass and string tension. Which MUST be identical in guitars with the same saddle-nut distance... which in turn determines the scale length. So it wouldn't matter if the roller was on a stick extending out to TWICE the length of the guitar itself, or even more. The actual tension measured by an in-line tension guage or fishing scale, would be EXACTLY the same, regardless of nut to roller distance. As ne85a said, this would possibly change the feel of the deflection force, which would be less, the greater the string length, since the WHOLE string stretches, not just the nut-saddle part. (However, this would be more noticable if you pulled the string as in a bow and arrow, but less significant when actually playing IMO, as I have stated earlier.) But NOT the axial tension of the string itself. The thing that is confusing the debate further is that some folk are using the term "string tension" when they mean "stiffness" or "deflection force", which is not the same thing. Hey Deniz is a physics guy...has he got something to add here? [:D] Edit: OK I see Deniz has just added that caped or fretted strings have "more tension". Wow.. really? Like the axial string tension gets higher? In that case you have invented a "force amplifier" and a possible solution to the World's energy problems! Or does it just feel "stiffer"? cheers, Ron
