Rotosound Steve Harris SH77

first of all: the quality of the strings I got was top notch!

BUT:
Most people buying these strings are soundwise trying to get into Steve Harris territory. And there is your problem! While you can get the Harris feeling with it, the strings loose their brilliance very quick and start to sound dead. And with this I do not mean a nice flatwound oomph, but plane dead and liveless! Mr Harris seems to change these strings very quickly but I guess he gets a discount on these strings... ;-)
I also do not think that the more "traditional" flatwound user would like these strings. I know better alternatives...

Well these flatwounds from Rotosound are a custom gause for Steve Harris from Iron Maiden.

I use them in tune C so I like the bigger gause and the extra string tension they offer.Beware if you don't like big tension strings these may not be the correct choise for you.They are very stiff for standard tunings.

Out of the box they are very bright and after some hours of playing they have some stickiness to the touch.
Those "features" don't last so much and after a while (one week or so) they settle in.
Their sound after they settle in is mellow with clean highs without steping into roundwounds terittory.They have the "flatwound sound" but don't expect deep and boomy lows.They are very balanced,fairly hi-fi with a nice quality to the low mid and midrange imo.

The touch is smooth even though a bit rough for flatwound but believe me this won't be a problem.They are still smooth and very easy to play!
And let me tell you they last forever.I used them 7 years and they were going strong.

Only downside I can think of is that they are overpriced.
If they were cheaper I would still use them but 40 euros are too much compared to the Fender flats offerings for example which cost half of that.
Still a very good product and recommended!

This package is really heavy, the strongest strength known concerning strings. Strung onto the Harris Signature Bass they are much easier to handle than I would have thought in advance. Compared to thinner ones you should take this package as those strings sound much more balanced. If you seek the Harris Sound with the metallic highs you should know that you will only have this effect in the beginning because of the monel on the strings, but as typical for flatwounds, the highs will disappear in a while. What may help is some Fast Fret before you start playing and of course afterwards. Nevertheless even if the highs are gone, those strings still produce the typical Precision Bass tone you like.
