Looking for Megatar Strings?
You can get everything you need from these guys: www.kaliumstrings.com
They have high quality strings and good service.
If the gauge is off by a thousand or two it does not make a difference.
String gauge info below.
Straight Fourths Tunings:
Bass: C-.025w G-.035w D-.050w A-.065w E-.085w B-.100w
Melody: D-.009 A-.011 E-.012 B-.016 F#-.029w C#-.040w
Note: The original melody B-.016 can be bumped up to a .019 for a little more consistent tension. The .016 is how they have always been strung, but the .016 string is a little bit slack in my opinion. You can choose to keep it how it is or increase the size a little. It is a matter of personal preference.
Inverted Fifths Tuning:
Bass: C-.095w G-.080w D-.060w A-.030w E-.016 B-.010
Melody: D-.009 A-.011 E-.012 B-.016 F#-.029w C#-.040w
