Rotosound BS66 Billy Sheehan Bass Guitar Strings

Gearank Recommendation

The Rotosound BS66 appeared on our recommended list for Bass Guitar Strings from October 2017 until February 2020 when our eligibility criteria changed to exclude custom gauge sets.


The BS66 is made from stainless steel, which gives you a tone that’s fundamentally bright and punchy. It’s great for modern and aggressive music, as well as funk.

However, the BS66 is Billy Sheehan’s custom set, the G and E string are a different gauge, with the G string being thinner and the E string being slightly thicker.

In practice, this is going to cause a more substantial difference in playability than it will in tone.


  • Gauge: Custom (.043 to .110)
  • Material: Stainless Steel
  • Coated: No
These were previously on our main recommended list and only came off due to us changing our guide to focus on standard gauges. You can see our current recommendations at: The Best Bass Guitar Strings.
