Sensicore Octave Violin Set 4/4 Medium Gauge (2507)

My Supersensitive Strings 2507 give my violin the sound of a cello! I took my instrument to a shop, as the online reviews recommended a stronger sound post. The shop had to widen the holes where the strings run through the tuning pegs, and switch the standard fine E tuner for the much thicker new octave-lower E as well. They are phenomenal and I can't wait to play it with the band!

The deep sound was great fun to play with while they lasted. The strings were difficult to set up on any of my violins as often they were too thick to fit through the holes in the tailpiece. The G and D strings had nice tone, the A and E were dull and dim, in my humble opinion. They lasted about seven months before one snapped while the instrument was resting in its case.Overall, fun to try and I had a good time messing around with the bass sounds, but I won't purchase again unless I go to the time, money, and trouble to have a violin specifically fitted for these strings.

I bought these Octave Violin Strings for my old 4/4 student Roth. Check out the various fiddle fora; they will recommend you put these on an otherwise bright violin, which mine is. Happy with the sound, but not so happy about string longevity. Put the strings on in May this year. The sound is very cello-like (in the same range). Because the air chamber is still violin sized, you won't get the volume of a cello, however. Works best if you plan on amplifying the instrument.One day in June, I opened the case to find the E string had broken, right where it wraps around the ball end. I just used a D string from a regular violin set, tuned up to E. Just opened the case today (October) to play and found the D (original, not the E replacement) is also broke at the same place (right where it wraps around the ball end). Before this set of strings, I've never had any string in any of my (over 14) stringed instruments just break while sitting in the case. Due to the special fabrication and windings on these strings, you can't just break out the needle-nose and twist a new loop and be ready to play some more. At this rate, I would be spending several hundred $$ per year to keep this fiddle strung.

I've had a string set on my old German violin for over 3 years now. The tone has faded a bit, but it still has the growl of the deep bass sound you would not expect from a violin. I changed the bridge and I have a metal Thomastik tailpiece which doesn't put a bend on the ball end of the string so no stress there. The action is very high for string clearance and I cut the bridge very thick to accommodate the thickness of the G string..I have not tried the Thomastik octave strings, but they cost more than twice as much. I suspect because they are steel they will be brighter. The Sensicores are perlon and wonderfully flexible like gut strings, but surprisingly bright for a low pitched string. That might give you a clue as to the playing characteristics of these 2 string sets.
