same stuff applies, regardless of string gauge. forget what your tech said, as the baseplate on the Edge7 angles up, unlike an OFR. With the trem angle, use the pick as a rough guide but keep the trem baseplate knife edges perpindicular (horizontal) to the post. WIth that happening your trem will look like pictured in the setup area.
check the
retainer bar if the string(s) are pulling sharp when locking down. the tech setup area of jemsite covers that too
