String rollers

[Tom Servinsky]

As with any tool, anyone can over-do any procedure and to more harm than
good. The rolling method I use messages the string more than bearing down on
the string, which is where I agree, harm can be placed on the bridges.
Messaging the string ( non wound) can take much of the initial stiffness out
of the string, allowing settling of the string to occur more rapid. But no,
putting extreme pressure down on the strings as though one is doing a
chiropractic maneuver is not what my procedure suggests.
