Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Check the nut slot and bridge hole for the B string. Some basses cut for a .125 need the slot widened slightly.
If you moved up from a lighter gauge, yes. Higher tension pulls more neck relief and shifts intonation.
Nickel-plated steel is a little warmer and smoother under the fingers, and gentler on fret wear. Stainless is brighter and more abrasive.
No. This is a five-string set. Buying it for a four-string leaves you with a spare string and the wrong gauges.
