Rotosound RS555LD Linea Pressure Wound 5 String Bass Guitar Strings (45 65 85 105 130)

These are great sounding strings - super bright. Not as "smooth" feeling as I was expecting, but they certainly do not tear the flesh off your fingers quite the way 'normal' stainless roundwounds tend to do. Played though an EMG MMTW, they have HUGE booming tones in the double coil mode, and yet they exhibit a very pleasant 'light and hollow' twang in the single coil mode. This set is a perfect fit on my 35 inch scale Warmoth Gecko bass ( bridge is not string-through... )

Strung these on my acoustic 5 string. Obviously sounded great straight on, but noticed the reduced finger noise described by others isn't necessarily the case. The strings are class and after a hearing back live group audio I'm happy with the results.Only reason I'm not 5ing these is I can't visibly see or feel the difference between these and roundwounds as widely described.On the plus they are sonically excellent, providing lots of harmonics and great lows even on the low b

It seems that there are many different terms for what I know as ‘semi-flat’ wound strings. D’Addario call them ‘half rounds’! I have heard them called ‘tape-wound’ - quite a good description; ‘ground wound’; & the genre used by the top string specialist and therefore, the term that I prefer, ‘semi-flat’! So when you type in ‘semi-flat’ bass strings and you get Rotosound’s ‘Pressure Wound’ as your only option, what is one supposed to do?Under the magnifying glass: (with the red tortoise-shell p’guard in the background) is the ‘Pressure wound’. Although it’s very tight & microscopic, it is very definitely ‘round wound’. Brand new, they are very bright and particularly abrasive to the skin and to the fingerboard of my fretless bass. Whereas the picture containing my finger & thumb, shows the ‘semi-flat’ in all of its’ glory… and grubby state - gimme a break, they’ve only been in place for seven years!As for the quality, To my ear & opinion, they are excessively bright; too bright for a maple fretless board certainly. Higher pitched than the tops of say, the usual stainless steel eclectic quality of Elixirs. They will no doubt, dullen with age & you could obviously dial-out the amp or bass, but not at the expense of my fretless’ fingerboard.They are probably very good strings but they are certainly not semi-flat & are not for the fretless application.

The best Roto sound string

Been using these pressure wound sets for years now, I rarely need to replace them, they have wonderful longevity, except in cases where I'm stringing up a newly purchased bass. They are a very happy medium between round wound and flat wound strings.
