Warchal strings — violin, viola & cello
By AR Distribution · Last updated
Short history & innovations
WARCHAL builds on two generations of violinists and intensive materials R&D. Highlights include the helix (wavy) E to tame whistling while keeping clarity, the proprietary W-Core® synthetic core (Amber, Timbre), and transparent tension charts for setup decisions.
How to fit strings (general)
- Change one string at a time to protect bridge/soundpost.
- Back out fine tuners; use pegs until stable.
- Lubricate nut & bridge grooves with a soft pencil (or dry soap).
- Wind from the peg hole toward the pegbox wall; avoid crossing winds.
- Retune several times, then re-stand the bridge if it leans and the bridge feet are no longer flat on the belly.
Violin — choosing, fitting & fixes




| Set | Best for | Feel / sound | Notes |
|---|---|---|---|
| The Beast | Soloistic projection & stage power | 3 synthetic strings + helix E | Tensions at 327 mm; eco packaging. |
| Timbre (LEP) | Italianate complexity + stability | Gut-like response; helix E | Break-in ~10–15 min; D avoids hydronalium (sweat corrosion). |
| Amber | Warm, rich colour; anti-whistle E | W-Core® warmth | Great all-round choice. |
| Brilliant | Clarity + projection | Fast, focused | Also Brilliant Vintage (lower tension for antiques). |
| Karneol | Warm easy play | Velvety | Easy playability |
| Ametyst | Sparkling | Brighter | Easy playability |
Metal A options: Russian Style & Avantgarde
Warchal’s metal A strings are designed to pair seamlessly with synthetic lower strings:
- Russian Style A: classic metal A feel which a smooth transition across the A to D break; clear, focused tone.
- Avantgarde A (helix): helix geometry adds longitudinal elasticity for warmth and control, helping tame glassiness at the top.
Fitting notes (violin)
- Back out fine tuners; use pegs until stable.
- Graphite grooves; wind neatly toward the pegbox wall.
- Retune a few times; re-stand the bridge after stretch.
Troubleshooting
Whistling/glassy E: fit a helix E (Amber/Timbre) and check contact point/speed.
Bridge lean: normal during stretch — re-stand and retune.
Won’t hold pitch day 1: retune; stability follows short playing-in.
Viola — choosing, fitting & fixes




| Set | Best for | Feel / sound | Notes |
|---|---|---|---|
| Timbre | Flagship warmth + projection | W-Core® colour; fast to “speak” | Also available for ZMT tailpiece (extended lower strings/minimal silking). |
| Amber | Rich, warm, textured | A: metal with helix or synthetic | Choose scale: Medium (≈36–38 cm) or Long (≈38–40 cm) vibrating length. |
| Brilliant | Clear projection, fast response | Concert-hall focus | Popular with principals/section leaders. |
| Karneol | Warm, easy play | Comfort-first tonal balance | Great for good instruments that require a velvety sound with fewer overtones. |
History & what’s special for viola
Warchal’s Amber and Timbre lines use W-Core® to bring gut-like colour without gut instability. For viola, Amber uniquely offers two A options: a metal A with helix (for extra elasticity and warmth) and a synthetic A (for maximum blend). Medium and long vibrating-length options match common viola sizes.
Fitting guide (viola)
- Replace one string at a time, backing out fine tuners first.
- Lubricate nut & bridge grooves with pencil graphite.
- Tune with pegs only until stable; then bring fine tuners into mid-range.
- Check bridge vertical; correct lean after first tuning cycle.
- For the Amber metal A, the helix section sits in the bowed area by design.
Common pitfalls
- Swapping all four at once (risk to soundpost).
- Forgetting graphite — leads to noisy tuning and winding damage.
- Mismatching scale length (use Medium vs Long correctly).
Troubleshooting
Surface noise: reduce rosin, adjust contact point; Amber/Timbre smooth the top end.Cello — choosing, fitting & fixes



| Set | Best for | Feel / sound | Notes |
|---|---|---|---|
| Amber | Warm, full-bodied core with power | W-Core® warmth; metal A (helix) or synthetic A | Often lower tension than steel; settles in a few days. |
| Brilliant | Projection and clarity | Rich overtones; fast to settle | Pair with Prototype A for a firmer top. |
Fitting guide (cello)
- Change one string at a time. If loosening all, lay the cello on its treble side with the aim of preventing the soundpost from falling.
- Play ~10 minutes per string after fitting before moving to the next — reduces bridge creep.
- Use pegs until stable; bring fine tuners into range afterwards.
- Graphite grooves; neat winds toward the pegbox wall.
Troubleshooting
Bridge pulling forward forward: re-stand and retune; add the 10-minute play-in per string next time.
Scratchy upper strings: don't use too much rosin, adjust bow contact point; try Amber metal A for extra elasticity/cut. Synthetic cello strings require an adjustment in bowing technique and are less forgiving than metal strings.
Instrument feels over-tight: Amber and Brilliant are often lower tension than many steel sets; review afterlength/tailpiece if needed.
