What is changing in the Warchal range?
- Brilliant 2.0: the new violin and viola generation. Confirm the version and UK stock availability with your stockist during the changeover.
- Brilliant Vintage: being discontinued at the end of 2026. Brilliant 2.0 is designed for both contemporary and vintage violins.
- Ametyst fractional: being discontinued, with Brilliant Fractional available as the replacement range. Warchal currently lists Brilliant in 1/8, 1/4, 1/2 and 3/4. For 1/16 or 1/10, ask about remaining stock and suitable alternatives.
- Brilliant cello: discontinued and excluded from the current cello recommendations below. Prototype Cello A remains a separate product.
- Amber metal cello A: supplied straight, without the previous helix winding, from October 2026. The helix descriptions for Amber violin E and viola metal A are separate.

Choose by character, then check the setup.
Think about what you want to change: more warmth, clearer articulation, greater projection or a more comfortable response. Your instrument, bowing and setup all affect the result; a tonal description is a starting point, not a guaranteed outcome.

Brilliant 2.0
Clarity and projection for modern and vintage violins.
Timbre LEP
Gut-like colour with personal workshop service.
Amber
Rich warmth and a helix E.
| Range | Character | What to check |
|---|---|---|
| The Beast | Soloistic power, projection and response. | Helix E; silver-wound D and G. Published tensions use 327 mm. |
| Timbre | Gut-like complexity with projection and stability. | UK LEP workshop supply. Synthetic or metal A; IFT E option. |
| Amber | Warm, rich and textured. | Helix E; IFT E for integrated fine tuners. Current manufacturer specification: Hydronalium A; silver D and G. |
| Brilliant 2.0 | Bright, projecting and responsive. | Universal stainless-steel E with removable ball; Hydronalium A and D; silver G. Do not apply the original range’s silver-D option to this set. |
| Karneol | Warm, velvety and balanced. | Synthetic core; allow about three days to reach full tone and stable tuning. |
| Ametyst | Pure and focused; brighter than Karneol. | Full-size option. Fractional sizes are being discontinued; see below. |
Smaller violins: Brilliant Fractional replaces Ametyst fractional
Choose the string size made for the violin. Brilliant Fractional is currently listed by Warchal in 1/8, 1/4, 1/2 and 3/4; this does not confirm a direct replacement for outgoing 1/16 or 1/10 Ametyst strings.
The E has a removable ball. The D is silver-wound in 1/8, 1/4 and 1/2, and Hydronalium-wound in 3/4. Full-size Brilliant 2.0 specifications should not be assumed to apply to every fractional size.
Explore Brilliant Fractional or ask your stockist about the size and version available.
E-string fittings: ball, loop, universal and IFT
Match the E to the tailpiece and adjuster. Brilliant 2.0 and Brilliant Fractional use a removable-ball universal E. This does not mean every Warchal E has a removable ball.
Amber and Timbre offer an IFT E for integrated fine-tuner tailpieces, allowing for their shorter afterlength. Ask your stockist to confirm the required end fitting and version. A loop-end adjuster must be in good condition, with any specified protector fitted.
Metal A options: Russian Style and Avantgarde
Russian Style A offers a clear, direct response and a smooth transition from E to A.
Avantgarde A adds full-length helix construction for elasticity, warmth and depth, with a subtly wavy surface. Either may be considered in a mixed setup.
Already using original Brilliant or Brilliant Vintage? Keep the generation clear when ordering. Brilliant Vintage is being discontinued at the end of 2026.
Viola: measure the playing length.
Measure the vibrating string length between the nut and bridge. Viola body length does not determine the correct string size.
| Range | Character & options | Size guidance |
|---|---|---|
| Timbre LEP | Gut-like response with projection. Standard set uses a synthetic A. | Standard Medium: 36–38 cm. Ask the workshop about specialised versions. |
| Amber | Warm and textured. Synthetic A or helix metal A. | Medium 36–38 cm; Long 38–40 cm. |
| Brilliant 2.0 | Projection and tonal richness. Synthetic or metal A. | Medium 36–38 cm; Long 38–40 cm. Confirm the generation supplied. |
| Karneol | Warm and velvety. Synthetic A for tonal matching or metal A for durability. | Medium 36–38 cm; Long 38–40 cm. |
Exactly 38 cm? Choose Medium for the ranges above. Check with a stockist before ordering for an instrument outside the stated lengths.
Synthetic A or metal A?
A synthetic A offers a close tonal match to the synthetic lower strings. A metal A provides a different feel and can offer greater durability. The choice is personal; it also needs a compatible tailpiece and adjuster.
Timbre and specialist tailpieces
Standard Timbre and versions for a ZMT tailpiece are different products. A specialist tailpiece may require altered string lengths and silking. Ask your LEP workshop to confirm the exact version instead of substituting a standard set.
Cello: warmth, colour and A-string choice.
| Product | Character | Practical notes |
|---|---|---|
| Amber | Synthetic-core warmth, depth and tonal texture. | Choose synthetic or metal A. Lower tension than conventional steel-core strings; allow about three days of playing for settling. |
| Prototype Cello A | Projecting metal-core A with a quick, direct response. | A standalone A string, rather than a complete set. Discuss pairing with your lower strings. |
October 2026 update: Amber’s metal-core cello A is now supplied straight, without the earlier helix winding. Older stock or photographs may show the previous design.
Brilliant cello is discontinued. It is retained only as historical context for existing strings and Prototype A’s development, not as a current set recommendation.
Fitting synthetic-core cello strings
Ask a luthier to check that nut and bridge grooves suit the strings. Synthetic strings can need a different bow speed and contact point from steel strings. Use the pegs for initial tuning and allow time for the sound to develop; avoid forcing a string through tight grooves or unsuitable adjusters.
Change one string at a time and monitor bridge position during tuning. If a bridge is leaning or its feet are not seated correctly, have it checked before continuing.
Fit carefully. Let the sound develop.
- Check the exact product. Confirm instrument, size, generation, core and end fitting before opening the packet.
- Change one string at a time. Keep the other strings at tension to help maintain the setup.
- Check contact points. Nut and bridge grooves should be smooth and suitable for the string. Pencil graphite can reduce friction; tight or damaged grooves need workshop attention.
- Fit the end securely and wind neatly. Avoid crossed or trapped peg windings. Tune gradually with the pegs, keeping an eye on the bridge.
- Use a compatible adjuster. Externally mounted metal fine tuners can damage synthetic cores at the ball. Ask a luthier to assess the setup rather than assuming every ball-end string suits every adjuster.
Settling time varies by range and instrument
- Karneol and Ametyst: typically about three days for full tone and tuning stability.
- Brilliant 2.0 violin: described as having a short break-in; the viola version may take three to four days to reach full tone.
- Amber cello: about three days of playing to settle.
- Timbre: has a specific initial routine—roughly 10 minutes at moderate dynamics for violin, or 10–15 minutes for viola, with retuning. Tone continues to develop over several hours.
Tuning stability and full tonal development are different milestones. Follow the instructions for your exact set; do not heat or rub strings to accelerate break-in. See Timbre break-in and care.
Cleaning: dry cloth, without liquid cleaners
Remove perspiration and fresh rosin regularly with a dry microfibre cloth. Avoid excessive pressure, liquid solvents and steel wool. For fused rosin, Warchal describes gentle removal with a plastic card; ask your luthier to demonstrate if needed.
Whistling E or uneven response
Check bow contact point, string crossings and accidental left-hand contact with the E. A helix E may help reduce whistling, but it does not replace a setup check. For persistent problems, tell your stockist the string range, fitting, instrument and symptoms.
Pitch instability, bridge lean or repeated breakage
Initial retuning is expected. Persistent slipping, a string catching in a groove, a moving bridge or repeated breaks at the same point need a setup check. Do not keep tightening a string that is binding. Ask a luthier to assess the pegs, grooves, bridge and adjusters.
Buying Timbre through UK LEP workshops.
AR Distribution’s TIMBRE LEP network supplies strings in person through selected luthiers and repairers. Workshop strings arrive straight in protective tubes, with advice and a complimentary string change if needed.
Contact the workshop before travelling to confirm stock and fitting arrangements.
Identification, codes and tension charts.
Pegbox colours identify the string position across violin, viola and cello. They do not identify the range by themselves.
Compare tensions on the same basis
Match the instrument, string version, vibrating length, pitch and units. A higher number alone does not predict better projection or a better match. The Beast’s published violin figures use 327 mm; current Amber and Timbre violin figures use 326 mm at A = 440 Hz.
Use current manufacturer product pages for the precise version. Older tension and item-code charts may describe outgoing strings; do not transfer their values or options to Brilliant 2.0.
