Informative I built a free web tool to search & compare classical guitar strings across brands (gauges, tension, material, and tonal specs)
Hey r/classicalguitar!
As a long-time classical guitar player, I’ve always found it tedious to compare string specs across different manufacturers—especially when trying to fine-tune treble/bass combinations or balance tension across strings for my own instruments.
To solve this, I built a free, lightweight web app called ReString Logger, and I recently rolled out a new Cross-Brand String Search & Comparison feature.

🌟 What this tool does:
- Side-by-Side Comparison: Compare tension (kg/lbs), gauge (mm/inch), and material (Nylon, Carbon, Titanium, etc.) between any two sets or individual strings.
- Tonal & Tactile Profiles: Visual graphs for Brightness, Sustain, and Flexibility for quick comparisons.
- Individual String Filtering: Great for custom set mix-and-matching (e.g., finding the right carbon 3rd string).
- Zero Friction: Completely free, no login required, runs directly in your browser (PC & Mobile), and supports English / Japanese.
🔗 How to Access:
Since direct promotional links are restricted, you can try the tool by searching for "ReString Logger". I can also share the direct link in the comments if requested!
I built this purely to give back to our classical guitar community and make string selection a bit easier for all of us.
I’d love to hear your thoughts, feedback, or suggestions:
- What string brands or models would you like to see added to the database next?
- Are there any useful features to be added?
Looking forward to hearing your thoughts and answering any questions! And if anyone wants to test it out, let me know and I'll drop the link/info in the comments!
