Solar Guitars equipped with Evertune bridge comes with standard tension saddle modules installed except for a custom low tension saddle module for the 2nd string.

If you want to change the string gauges and/or tuning you have to check that the saddle will handle the tension with the Evertune String Tension Gauge Calculator

Note: you can find the scale of your guitar in our website.
