Rondo violin strings work on many different instruments but are particularly popular among soloists playing old instruments. The RO100 set comes with a synthetic core, aluminum wound A-string, providing great modulation and a rich spectrum of sound colors. For those wanting to stay true to the traditional steel A-string or looking for 100% corrosion resistance and easier playability, Rondo offers a steel A-string without the common downsides of sounding too bright or shrill.The E-String comes with a separate envelope that contains the bridge protector (many times this is not needed if your bridge already has a parchment on it) as well as an "attachable ball." The E-string is a loop-end by default, but you can insert the included ball if needed.Great balance of warmth and brillianceSoloistic powerVast dynamic rangeImmediate bow responseReduces intensity of wolf tonesSet CompositionE-String: Tin plated over carbon steel core | Removeable Ball (18.1 lb)A-String: Aluminum wound over synthetic core (12.6 lb)D-String: Silver wound over synthetic core (10.6 lb)G-String: Silver wound over synthetic core (10.6 lb)
