I too highly recommend fining a good luthier. I inherited my mother’s violin that was in our family for 2 generations before I played it. I was never really pleased with my sound, so would not be motivated to practice much. I eventually brought it in to upgrade the chin rest, tailpiece, refit the sounding post, better pegs and a good set of strings. I added to the package a very high quality bow. Without the bow, the appraised value of my instrument went from $1500 to $4000, and the sound is great. I now have the motivation to tackle my technique challenges and really enjoy my sound. In general, it’s really important to replace strings and have the bow rehaired at least once a year.
