All Righty Then! 'The Sound of Pumpernickel' it is! I decided to go with the light GHS 4L-NB set for my American Standard jazz. I want the more mellow sound of Balanced Nickels. Not a fan of light gauge strings, but went with them anyway for the shallow & narrow jazz neck.
I have tried the BN 4L-NB on my P and was pleasantly surprised at how meaty they felt and sounded. "Light gauge" doesn't have to mean "wimpy".
Here are interesting comparisons in tension figures:
Boomer M3045 (45-65-85-105) = 186.5 lbs. in total tension.
Balanced Nickel 4M-NB (44-60-80-106) = 184.2 lbs.
Balanced Nickel 4L-NB (40-56-76-101) = 172.3 lbs.
RC Boomer RC-M3045 (45-65-85-105) = 172.1 lbs.
Balanced Nickel 4M-NB (44-60-80-106) = 184.2 lbs.
Balanced Nickel 4L-NB (40-56-76-101) = 172.3 lbs.
RC Boomer RC-M3045 (45-65-85-105) = 172.1 lbs.
As you can see, the total tension on the 4L-NB is almost identical to the Round Core Boomer 45-105 (your other favorite) despite smaller gauges.
