Choose Gut strings match plain gut A strings
I Love Gut strings which give me lot of character of tone, Eudoxa D and G I use on my violin, sounds are perfect but very slow response. any people can tell me which brands of any strings can replace those and have bit fast response and maintain similar tone match of my plain A Gut Strings.
Regular Eudoxas or Stiff?
I would recommend Passione if you want faster response.
Different rosins might affect the response time of your strings. They certainly can change the sound generated.
I agree with Mr. Victor-rosin (or its application) may be affecting the rrsponse of thr Eudoxas. I still have my old Eudoxa stiff G&D and they have faster response than many old synthetics would-VERY easy to play and respond.
I am also puzzled as to why gut strings are described as "slow" by the synthetic string makers. They are more flexible, less inertia. They did not seem to slow down Mr. Heifetz.
I think gut has slower response than synthetics simply because the diameter is much larger and it takes more energy to start moving, at least it feels that way. Funnily enough, this is why I love gut strings. The slow response means that playing nearer to the bridge and starting strokes on the string is necessary. That 'kkkk' start up of the sound is what gives articulation in a large hall.
Slow response might be caused by a higher gauge. Some violins sound better with light gauge, no matter if material is gut or synthetic. This especially if it is a long pattern with longer VSL. Then, behaviour of G string depends so much on bass-bar that it is altogether another can of gutless worms.
