The basses are their Traditional 520B bass strings. I used the 520B set quite a lot on my old Ramirez George Harrison. After the strings have settled, check the neck relief. On my guitar the neck would get completely flat, and I mean no relief at all, seasonally and would buzz. I wound up putting on D'Addario EJ45 med tension that were only about three pounds heavier in tension than the Savarez. After the season changed, the low tension Savarez went back on it.
The Ej45 was 86.1 lbs tension, and the 520B was. 83.37 lbs. The difference was just enough to put some relief in the neck, and the buzzing stopped. Putting the EJ45 set on raised my action 1/64th on my Ramirez. I'm still using the Savarez on my daughter's Ramirez 2NE. She likes the feel of the rectified trebles.
