Normal ala Ibanez etc. is 45-105 Roundwounds...
If ya an Earnie Ball guy and Extra Slinky (8-38)... you may wish to stay Extra Slinky (40-95) or A Rotosound Guy?... check their sites Nickel or Stainless - and what and why may be the place to start...
I was 9-42 mainly due to a locking trem, but with a wound 16 3rd for more substance and feel, i felt 16 was too thick for a plain bit if wire... 14 maybe.
Whatever ya get will prolly be strung with 45-105 so try them first...
Mark 'Slap' King style lighter 30-90... 40-100 std 45-105 or Steve 'Gallop' Harris Heavier 50-110 (and flats)...
What ya gonna do with it? slap n snap n tap, or finger and pluck 😉 Bend or Bimble along?
Then later on ask about flats... which are often 45-100... and tension...
