Thomastik Vision Solo 4/4 violin string set (Re-aluminum)
Vision Solo sits in the middle of the Vision family: the maker describes it as an advanced synthetic core with "energetic and intense projection with a warm tone and focused harmonic content", plus "quick bow response and short play-in time". VIS100 is the one of the two sets in which the D carries an aluminium winding (VIS03, 4.6 kp). The E is tin-plated carbon steel with an aluminium removable ball end at 8.1 kp, the A is aluminium wound at 5.6 kp, the G silver wound at 4.7 kp — 23.0 kp (50.7 lb) in total over a 32.5 cm vibrating length. That is 0.3 kp above the basic Vision set, and the difference reads as firmer resistance under the bow and a more willing response at forte. The hardware is specific too: aluminium ball ends, a lighter metal at the tailpiece than the usual brass.

🏆 SoundsGood — genuine Thomastik-Infeld strings only, made in Vienna.
Advanced Core: Quick Response, Short Play-In
What Thomastik claims for Vision Solo is mostly about the first days and the first fractions of a second: "quick bow response and short play-in time", together with "superior tuning stability". Two things follow in practice. First, the set does not keep you waiting a week — after a few hours of playing it stops creeping and settles into the timbre you will actually live with, which matters when strings go on a day or two before a concert. Second, the attack reads at the very start of the bow stroke rather than after a run-up, so short notes and staccato do not get swallowed.
Aluminium D Against Silver: What the 0.3 kp Buys
Vision Solo makes the D in two versions, and that single string is the whole difference between the line's two sets. Here it is the aluminium VIS03 at 4.6 kp: aluminium is lighter than silver and adds less mass to the winding, so the D comes out more transparent and open, with a clearer top to its own range. The silver version (VIS03A, 4.9 kp, set VIS101) sounds denser and darker and lifts the set total to 23.3 kp. If your instrument is already thick through the middle register, the aluminium D unties that knot instead of adding weight to it.
23.0 kp and Aluminium Ball Ends
The total is laid out without soft spots: 8.1 — 5.6 — 4.6 — 4.7 kp. The E is 0.1 kp tighter than in the basic Vision line and the A 0.1 kp tighter than the family's orchestral options, which together give the instrument a taut feel — the bow meets resistance immediately rather than after you press. One detail you notice while fitting: every ball end here is aluminium, and the ball on the E unscrews to expose a loop, so the string works with a fine-tuner hook and with a loop-end holder alike.

What's Included
The official package holds four strings — E VIS01, A VIS02, aluminium-wound D VIS03 and G VIS04 — each with its own Thomastik article number. The set article is VIS100 and covers a complete restring with no single voices to add.
Who It's For
A set for the player who has outgrown the basic Vision line and wants more projection without jumping to soloist tension; for anyone who needs a transparent, open D on a thick-sounding instrument; and for the musician who restrings a day or two before a performance and cannot afford a week of playing-in.
Frequently Asked Questions
What exactly is in the VIS100 set?
Four 4/4 strings in medium gauge: E VIS01 in tin-plated carbon steel with an aluminium removable ball end (8.1 kp), A VIS02 with aluminium winding (5.6 kp), D VIS03 with aluminium winding (4.6 kp) and G VIS04 with silver winding (4.7 kp). Total 23.0 kp.
How does VIS100 differ from VIS101?
By exactly one string, the D. VIS100 carries the aluminium VIS03 at 4.6 kp, VIS101 the silver VIS03A at 4.9 kp, which lifts the set total from 23.0 to 23.3 kp. The E, A and G are identical in both sets.
How does Vision Solo differ from the basic Vision line?
The A, D and G here use an advanced synthetic core, the total tension is higher at 23.0 kp against 22.7 kp for the VI100 set, the E is 0.1 kp tighter (8.1 against 8.0) and the ball ends are made of aluminium. The maker claims more energetic and intense projection with a warm tone, quick bow response and a short play-in time.
Which gauges and sizes does Vision Solo cover?
One gauge only — medium — and one size only, 4/4 with a 32.5 cm vibrating length. Neither light nor heavy versions nor fractional sizes are published for this line; if you need a fractional size, the professional option in the family is the basic Vision line.
Can I fit the silver D in this set separately?
Yes, that is a factory option: VIS03A (silver, 4.9 kp) replaces VIS03 (aluminium, 4.6 kp), and that combination is exactly what the ready-made VIS101 set contains. The 0.3 kp difference is small enough that the other strings need no rebalancing.

Yes. SoundsGood supplies only genuine Thomastik-Infeld product in official packaging marked with article numbers.
