Why Alloy5109 ?

Alloy5109 strings are treated with an environmentally safe polymer liquid that evaporates quickly. REDF.R.E.D, (a Sfarzo Brand) polymer coating creates a resistance between the string wrap and core against acidic perspiration. Our polymer coating lubricates and protects against premature corrosion, slowing down the corrosive process while still retaining excellent tone.


“Hi just sending feedback on sfarzo bass strings I purchased from you at guitar show in Urmston. Put them on Jazz Bass and blown away by improved tone and volume. Best strings I’ve ever had on my Bass”.

– Tom Morgan

“Used Sfarzo strings for the first time at a gig last night. Amazing. They kept their tune better, felt better and have better tone than anything I have used before. I recommend that you get some of these”.

– Mike Grubert

“I have re-strung with your strings and am very  impressed!”

– Judd Lufthouse

Alloy 5109s

A great set of strings! The coating didn't feel sticky. The tone was nice, not to bright and not so warm that definition was lost. I play through bartolini pups and an Aguilar tone hammer and my tone was great! It was an outside gig in Florida humidity so I was curious to see how they held up. Next day, string still felt great!

Alloy 5109 Bass Strings

I have been using these on my bass guitars for years now...They feel great on the neck and deliver massive sounding tones....Grab a set and hear for yourself or better yet give them all a try.....You cant go wrong with Sfarzo strings!
