Vintageflex acoustic strings from Optima
Optima Vintageflex acoustic strings come as low-tension six-string sets for acoustic guitar. Choose your preferred gauge from 10-43, 11-47, 12-51 and 13-55.
Choose the right version
The gauge range gives the diameters of the thinnest and thickest strings in thousandths of an inch. Compare these numbers with your current set before making your selection.
Select a gauge to display the matching price, availability and package image. Check the chosen version before adding your set to the cart.
First, compare these specifications with the strings currently on your instrument. This gives you a useful starting point when choosing a replacement. Then check the available options before adding the product to your cart.
Plan your next string change
If you want to keep a familiar playing feel, start with the specifications of your current set. However, if you plan to change gauge, material or tension, check your instrument maker’s recommendations first. Your teacher or repair technician can also help you choose a suitable setup.
During installation, bring each string up to pitch gradually. Then check the tuning again before playing. A change in your string setup may require an adjustment to maintain comfortable action and accurate intonation.
Handcrafted in Germany
Optima makes its strings by hand in Germany using premium materials. The brand brings more than 100 years of string-making experience to its range for musical instruments.
