Hi guys - this is my first time posting in this forum. I decided to return to D'Addario J62's after my son said my 1917 Gibson A was overpowering his rhythm guitar's volume with J74's - and after reading some of posts' concern for a vintage mandolin's top and neck with heavier strings. The lighter strings allow me sufficient volume and a pleasing tone from my teens Gibson and have the added benefit of being a bit easier on my finger tips. - Dan
