Good strings

Lorcan C. 26.01.2021

I usually play Dominant Thomastik Medium (GDA) with a Warchal (Amber 701L) loop end E string. I thought I'd try these out after seeing them recommended on YouTube.
The high quality and tone are exactly what one expects from Thomastik strings, however, I find these strings sound a little more brilliant than suggested on the Thomastik guide*. Maybe that's just me.
Strings are such a personal taste, and I recommend any young player to explore different strings. You will not regret trying these. I really like them but as a personal preference I'll probably return to the Dominant.**

*Update - It was just me! One month on and these strings have settled in beautifully. I'm going to stick with them as my go to set of strings.
**Still love the Dominant Strings but the Infeld set are just a fraction smoother/ sweeter.

Easy to play and easy to add expression

JosepS 17.12.2017

I used the PI for a while and i not like them very much. The sound is well defined. Projection is good. Sound is not too soft. I think the most interesting point is the durability and longevity of the string. In the end they were very easy to play and are easy to add expression.

Good high quality string.

SJWIrishFiddle 27.04.2026

For my violin ~15000€ Luthier hand made del-gesu style copy. Almost as good as Evah Pirazzi Gold in sound quality but much more durable. 48 hours of settling in time, but still okay during the first day or so. Playing in cold, then hot, humid or dry it wont suddenly die on you sound quality relatively consistent. If its under 100€ a set with a Hill E string then its economically viable for a pro/semi pro too. Out of principle i wont go much above say 80€ for a set where i'm changing out the E for something a little better. Hence these are good strings.
