When all else fails and you already bought picks (plectrums) then guitar strings are an awesome stocking stuffer for any guitar player. Available in Single Sets, 3 Packs and 10 Packs, D’addario has you covered. Not sure what gauge to buy? Standard or Regular Gauge for Electric is 10-46, for acoustic is 12-53 and bass is 45-100. If you are buying Classic/Nylon Guitar strings then just choose Normal tension strings. You can’t really go wrong with these gauges, so if you aren’t sure what the guitarist in your life typically uses, choose these. You can also take a photo of the guitar and take it into your local music store. While they won’t be able to tell from looking at a pic of the guitar, they will have a better idea of what to recommend so that you get the right gift!
