1) The use of metal strings - which are so widespread today - due to their high working tension involves a considerable strain on the fingers, joints and muscular system, which, in the long run, can lead to real work-related injuries of a disabling nature at the joint and cartilage level. All our double bass sets are designed to prevent this very type of problem.

2) The transition from metal strings (a much stiffer material in itself and generally with greater tension) to our sets could easily involve the need to adjust the action of the strings on the fingerboard.

3) For those who have always used metal strings: it is perfectly normal for the D string to be more dull and muffled than the G string. In other words, it is not a defect but a typical characteristic of plain gut strings and gut wound with flat Nylon, together with the related synthetic sets. To overcome this acoustic disparity, the 'Red Springs' G and D strings were introduced, where the D string is made with a special technology that evens out its performance with the G string. The same applies to the 'Red Springs Metal' G and D.

4) The G and D strings that are wound with flat nylon thread (Gold Springs Vintage, Gold Springs Synthetic, Red Springs) are by their nature fragile: during the installation and tuning phase a 'shearing' effect may occur on the nylon covering the section that's free of the protective colored silk. To prevent this from happening, make sure that during the initial stage of winding the string around the peg there is only the section that's protected by the silk.
