Spirocore Bass Strings

Spirocore bass strings are still by and large, the upright bass strings of choice for most jazz bass players.  They have a stiffer core than usual, and offer more sustain (and 'growl').  While Spirocore upright bass strings are still sometimes used for classical bass players, they tend to primarily only use the E string. The E will have more punch and 'speak' easier then the usual E strings that come with more classical oriented sets (like the Pirastro Flexocor series.)  For bowing though, they tend to be too bright to use as a whole set, at least in a total orchestral bass setting.  Some upright basses (the rare, super dark toned) can tolerate them, but still not the bowing string of choice.

Buy Spirocore upright bass strings

We still offer the cheapest prices on all of our upright bass strings, especially the Thomastik Sprirocore brand.  How often do you need to change your strings?  This really depends on the amount of playing done (hours added up), the bass and the tastes of the upright bass player.  Some players really like brand new strings, and others like newer strings, but only after they've played in a bit (2-3 weeks.)  It really depends on the bass as well.  Some basses that tend to sound super bright (and don't need any help in that department) and will sound best after the strings are played for a few weeks. Some players will purchase strings in advance of any significant recording so that the strings will not sound too "raw" the day of the recording. Buy Spirocore bass strings.

The most popular used Spirocores, are the S42 (Orchestra gauge). They have a bright red winding near the tailpiece AND the same color winding on the ends of the string.  The Light Gauge (Weich) has the same color red on the tailpiece end, but in the scroll a light purple winding.  The solo Spirocores (red on the bottom and yellow in the scroll end winding.)
