Warchal Amber E Violin String 4/4 (Loop-End, Medium)
701L is the Amber E with a loop end, made for fine tuners and tailpieces that take a loop. Structurally it is the same solid unwound stainless steel string with the maker's helix design: a coiled section that Warchal calls "an innovation that increases the longitudinal elasticity of the string", which in turn "minimizes the risk of whistling". For the medium gauge the manufacturer states 82.37 N at a 326 mm vibrating length and 440 Hz — the end shape does not affect that figure, because Warchal treats it as an option separate from gauge. Within the Amber line this E joins the synthetic W-Core® A, D and G, but it works just as well over another brand's set. The character is clear, focused steel with no edge in the high positions.

Loop End: When You Need Exactly This One
A loop-end E is what you need if your tailpiece carries a fine tuner with a hook: a ball-end string either will not fit that hook or will sit crooked in it. Amber has no removable ball — 701L and the ball-end 701B are two different articles, so you buy the right shape rather than improvising with pliers. Warchal also makes matching adjusters: a dual-use model for loop and ball ends, and a Wittner type specifically for loop-end E strings.
A Coil in the Steel: Elasticity Instead of Whistling
What sets the Amber E apart from an ordinary steel string is geometry, not alloy. The coiled section makes the string more elastic along its length, and the maker calls it an innovation that brings a significant sound enhancement and minimizes the risk of whistling. For the bow arm that means the first string responds more gently at the start of a note and does not break into that parasitic overtone when the bow sits at an awkward angle — the most common cause of a spoiled crossing in fast passages.
Tension Instead of Diameter
Warchal deliberately publishes no gauges in millimetres: every table from the maker gives tension in newtons for the same conditions, a 326 mm vibrating length at 440 Hz. For the medium E that is 82.37 N, and this number tells you more than a diameter would — it sets the resistance under the finger, the load on the bridge, and how the first voice sits next to the rest. If you want more, the line offers a forte loop-end E, article 701FL at 86.30 N.

What's Included
One loop-end E string in official Warchal packaging marked with article 701L. You need your own loop-end fine tuner; it is not included.
Who It's For
A string for the player with a loop-end fine tuner who would rather not deal with adapters; for anyone who wants a steel E that does not whistle at the familiar 82.37 N; and for the owner of a loop-E Amber set whose first string needs replacing before the synthetics do.
Frequently Asked Questions
How does 701L differ from 701B?
Only in the end: 701L has a loop, 701B a ball. Material, medium gauge and the helix design are the same, and the maker quotes tension by gauge for both — 82.37 N.
Can a loop-end E be fitted to a plain tailpiece with no fine tuner?
No, the loop needs something to hook onto: either a loop-end fine tuner or a hook built into the tailpiece. If your tailpiece has a plain ball-end slot, order 701B instead.
How does Warchal state tension for the loop version?
The maker ties tension to gauge and treats the end as a separate option, so medium is 82.37 N. The official summary table has no dedicated 701L row — it lists the ball-end variant with the same figure.
What does the helix design do?
The coiled section increases the string's longitudinal elasticity; the maker states this significantly enhances the sound and minimizes the risk of whistling. Whistling is the very reason most violinists replace the first string.
My tailpiece has integrated fine tuners — should I take the loop?
No. For those tailpieces Warchal makes a separate ball-end version with the shorter afterlength accounted for — 701B IFT, or 701FB IFT in the forte gauge.
