Tension is not gauge alone
Unit weight, vibrating length, and frequency determine tension. Two equal-diameter strings with different construction can have different unit weights.
Recheck the system
After a meaningful tension change, stabilize tuning and recheck relief, tremolo balance, nut movement, action, and intonation in that order. Do not cut a nut slot from a calculator result.
Compare supported tensions and then use the gauge-change planner.
Scope of this guide
Plan gauge or tuning changes around published tension data and follow-up setup checks. Use String Gauge Changes and Setup Effects to make a repeatable decision for this named task, not to impose one specification on every instrument.
Practical example
A move from 9–42 to 10–46 while tuning down mixes an upward gauge effect with a downward frequency effect. Use published unit weights for an exact supported comparison, then stabilize and recheck nut movement, relief, tremolo position, action, and intonation.
Record the conditions
For String Gauge Changes and Setup Effects, write down instrument type, tuning, installed strings, relevant hardware, climate when material, physical datum, unit, tool resolution, and the result before and after change. A result from this guide is comparable only when its method travels with the number.
Verification checklist
- For String Gauge Changes and Setup Effects, confirm the starting state and exact question.
- Repeat its critical measurements from the same reference.
- Compare its result with direct observation and applicable maker documentation.
- Change one reversible variable where the task permits.
- Retest the named symptom and preserve unresolved exceptions.

Limits
String Gauge Changes and Setup Effects cannot inspect hidden structure, material condition, service history, or player technique. Stop this guide workflow for electrical hazards, abnormal resistance, structural movement, conflicting readings, or unplanned material removal.
