Spirocore Upright Bass Strings

Spiros are an old favorite for jazz and other genres and has been a popular string for many years. They were one of the first decent metal strings to be adopted by strictly gut string players-- in fact, lots and lots of us played G & D guts and A & E Spirocores, since the larger gut strings of the mid-20th century still were too indefinite and flabby for good jazz articulation. 

They have great sustain and a big sound good for many styles, but remain a jazz favorite. You'll also find them on lots of general use basses, for bluegrass, blues, and other styles where that big sound and sustain are prized. While they are certainly used by many fine arco players, they have a reputation for a scratchy sort of response under the bow -- and their stiffness requires an attention to proper technique. So if you bow a lot, and not strictly acoustically (scratchiness is particularly obvious when amplified), consider that reputation. I have used them sucessfully with magnetic pickups. 

We carry the standard "Medium" Spirocores, as well as the Weich, or light weight gauge, which are more flexible and lighter. The modern string packages say "Orchestra," which refers to conventional orchestra tuning. We also carry the "Red Mitchell" Signature set, which is a set for tuning in 5ths, which is favored by some players. 

Trying to replace the Spirocore strings you already have? Spirocore Medium (Regular Gauge) have RED windings at both the tuner end and ball end of the string - while the Weich (light) gauge strings have a PURPLE winding at the tuner end and RED winding at the ball end.
