Final check

Product questions
Straight answers to the questions shoppers most often ask about this product.
No. This is a four-string set. A five-string bass needs a dedicated five-string set with a low B included.
That's the point of the format — two sets bundled at a lower combined price than buying two individual packs.
Sealed packs hold up well. Keep it out of damp environments and away from heat and it'll be fine until you open it.
They fit standard long-scale four-string basses. Check your scale length and string spacing first, especially on short-scale or unusual instruments.
