The original and best known synthetic cored string. Regarded as the reference standard for this type of string. Well adapted to give excellent playing properties on any instrument.

Dominant strings give a warm and clear sound which closely approximates to a traditional covered gut string. Tonally stable and easy to play on they suitable for all players beginner to professional.

Available in three tensions in full size and medium tension in fractional sizes. Aluminium wound on a multi-strand synthetic core.

To check your instrument size measure the length of the back (LOB) excluding the 'button' which is the thumb shaped extension at the top where the neck is anchored. Old instruments can vary, if more than 1/2" over choose the next size up.

The Dominant set is let down by the ‘A’ string...
24 out of 25 found the following review helpful

Pros: Dominant strings - as a complete set – are quite rightly the popular choice of ‘universal’ synthetic core string that suits most instruments and most players’ needs. Reliable in tuning stability and tone and reasonable in price – however, badly let down in my opinion by the construction quality of the ‘A’ string….

Cons: A quick read of the other reviews, a search of the internet or even just ask other players and everyone always says the same thing - good strings, but the ‘A’ string unwinds quickly after use and doesn’t last long! Why, oh why then does Thomastik not actually DO something about it then! Clearly there is a construction problem with the A’s for this to be such a commonly experienced problem with so many different users and on so many different instruments – this can’t all be a usage or fitting problem or even sweaty fingers as is usually blamed. I congratulate Thomastik overall on a good string – overall the set is great, but don’t rest on your laurels, things can always be improved – a problem has been identified by your customers – please do look into how this can be remedied unless you’re quite content to be forever known as the ‘good set but poor quality A’ brand of strings that is…

Other: This ‘A’ string is soooo frustrating! In terms of tuning and tone it’s great, but it unwinds at different points of the string spontaneously in next to no time! I won’t be getting replacement Dominant A’s again until they sort this out!

Heavier gauge Dominant A
4 out of 4 found the following review helpful

Pros: This works much better on my fiddle than the standard Dominant A string. Louder, clearer and altogether stronger sound. Also less inclined to sound a bit on the scratchy side with my playing. All violins are different but this string certainly suits mine. I've never mixed sets of strings before but would recommend experimenting. I now use the standard Dominant G and D strings, the heavier gauge A and the Kaplan/d'Addario Golden Spiral 'Solo' E string, which is much better than the standard Dominant E

Cons: Nothing

Other: Thanks String zone for the advice and usual efficient service

Dominant Violin Strings
3 out of 4 found the following review helpful

Pros: I've used Dominant strings for several years and I am really happy with the G D and A although I do now use Pirastro Gold Label for the E string as it goes really well with the Dominant strings but I think it has a richer tone.

Cons: None.

Great choice - poor process
1 out of 1 found the following review helpful

Pros: choice of strings available

Cons: Why it took 5 days to actually process the shipment. If it was processed on the same day, first class, there wouldn't be a necessity to have to pay for faster shipping.

Lively sound and great value for money.
1 out of 1 found the following review helpful

Pros: I like the bright sound on my fiddle and what to me seems like a good response. Also once tuned they stay tuned (except in large temperature changes - which is understandable. Great value.

Cons: I play in open air and in pubs - they tend to deteriorate quickly under these (not ideal) conditions.

Other: This was a replacement A to make up the set.
