Pain Management hat
Is the pain;
- In your fingertips?
- Your fingers?
- Your palm?
- Your forearm?
- A combination of some/all of these?
The pain could be stemming from a number of issues, not just what kind of strings you're using. My next question would be, "What do you do for a living?" since repetitive stress comes in all flavors. Then there's more medical questions that would follow (family history of arthritis, old injuries/surgeries) that I won't ask in an open forum
y'know, privacy of the client and all that.
But, back to the "strings" question
My first strings were D'Addario Chromes (100's, I believe) and were a good starting point. They were easier on my fingers and had some decent tension and sound. Later, I started trying out different roundwounds, an even lighter set of D'Addario Chromes (95's, I don't recommend them
a little weak, sound-wise) and one set of GHS Nylon Tapewounds (I'd only suggest them if you want a very soft, "woody" thud).
My current favs are the Ernie Ball Cobalts (100's), but I like the very aggressive and punchy sound I get out of them. I don't know if that would work for your professional soundscape. However, since they specialize in strings that are, as they put it, "slinky", but still deliver sonically, perhaps trying a set of their Group II or III's might reduce the pain you're experiencing. I, myself, haven't tried them yet, but it is the foundation for their "string doctrine". I might get some for a build project that's lurking in the back of my mind.
If you want some further advice, pain management-wise, feel free to shoot me a Personal Message.
Good luck!
