Why S.I.T.?

S.I.T. String company has top notch customer service, besides having the best strings in terms of quality, price, and sound. Also we have to mention the feel and tone, S.I.T. has blown us away with their clarity and playability. We are so thrilled to be with a company that makes such a fantastic and reliable product for the touring professional!

Definitely our favorite strings that we have ever used!!! Joe uses the Power Wound strings for his electric guitars, and the Phosphor Bronze strings for his acoustic guitar. “I just switched to a custom set of 9-48 for my acoustic, and I run a custom set from 8-60 on my 7 string electrics.”- says Joe. Sammy uses the power wound nickel bass strings and have become his all time favorite because of tone and playability. Jaime uses Power wound nickel extended range, .064-.095 and he ain’t looking back! Thanks S.I.T. Strings!!
