Overview
Restringing an acoustic with these Martin Retro strings swaps bronze for a nickel and copper Monel wrap that resists corrosion. This medium light set is the signature choice of guitarist Laurence Juber.
Monel wire softens plectrum attack so the guitar's tonewoods dominate, and it resists corrosion without a coating. The voice is warmer and less bright than phosphor bronze, which suits fingerstyle and vintage tones.
Who it's for
Fingerpickers, recording players and owners of fine acoustics who want the wood to speak get a mellow, durable set. Players who love bright, crisp bronze tone should stay with phosphor bronze.
Pros and cons
- Corrosion resistant Monel wrap
- Warm, natural tone

Performance notes
The nickel and copper wrap produces fewer high overtones than bronze, which reduces plectrum noise and lets body resonance lead. Its natural corrosion resistance slows tone loss from sweat.
