The SH77 is a result of Iron Maiden's Steve Harris' and Rotosound's long history of working together.

This set is designed to meet the expectations of Steve, and is the set that he uses for his main 4-string bass guitar.

Aside from being co-designed by Steve Harris, an important distinction that this string has is the use of Monel as its main material.

Monel is a nickel alloy that was very popular back in the early days of steel strings, but because of how expensive it is to make, most manufacturers have stopped using it. These days, there are now a few who have gone back to Monel, including the Rotosound SH77.

Features:

• Gauge: Heavy (.050 to .110)
• Material: Monel
• Coated: No

Pros
This set is consistently praised for getting the Iron Maiden sound right, and for heavy having tones that work great for similar rock and metal styles. It is also often used by bassists who de-tune their instrument, and interestingly, there are also reports of it working well in other genres. Being a flatwound set, many also welcome its smoother feel.

Cons
Being a heavy string, there are some who find the extra-tension to be a bit too much for their fretting hand.

Overall
The Rotosound SH77 is the set to get if you've got the bass and skills to handle heavy strings for heavy rock and metal playing.
