Lup-X Wolf Eliminator for Cello

Precisely adjustable brass wolf eliminator with minimal damping

The Lup-X Wolf Eliminator is designed to help control problematic wolf tones on the cello while minimizing unwanted damping. Made from highly polished brass, this compact accessory clamps directly around the string at a defined contact point. Unlike conventional wolf eliminators that use rubber, the Lup-X contains no rubber or similar damping material, helping the cello retain its resonant character across its range while addressing troublesome wolf tones.

The Lup-X mounts on the string below the bridge and can be moved along the string afterlength for precise adjustment to the individual instrument. Its two-piece brass construction screws together around the string, making installation and repositioning straightforward. Compatible with commonly used cello strings, the Lup-X accommodates string diameters from 0.6 to 2 mm. Its smooth, unobtrusive shape and polished brass finish complement the traditional appearance of the cello while providing a practical, adjustable approach to wolf-tone control.
