Get to know them!

Thomastik-Infeld Infeld bass strings are specifically formulated for modern electric bass guitars and deliver a warm, modern tone that's well balanced across the frequency spectrum. This set features a powerful Superalloy winding outer layer that's easier on your fretwork than stainless steel while providing fat, rounded lows, throaty mids, and solid highs without brittleness.

A legacy of quality from Vienna, the City of Music

Sweetwater is proud to offer you Thomastik-Infeld strings. Founded in 1919, Thomastik-Infeld has a long, storied history as a leading manufacturer of strings worldwide. Its co-founders, Dr. Franz Thomastik (a luthier and Doctor of Philosophy) and Otto Infeld (an engineer), were innovators in the development of materials and production techniques that made possible the reliable, modern strings we take for granted. Based in the heart of Vienna, the City of Music, the company today produces over 2,000 various types of strings for stringed and plucked instruments, and their strings have been adopted by world-renowned soloists such as Itzhak Perlman and Pinchas Zukerman.

Thomastik-Infeld Infeld Bass Guitar Strings Features:

  • Specially formulated for electric bass guitars
  • Faithfully capture the warmth, punch, and depth of your instrument
  • Superalloy winding outer layer is easy on your fretwork
  • Fat, rounded lows, throaty mids, and solid highs without brittleness
  • Meticulous tension, gauging; microprocessor-controlled winding for exacting string-to-string balance
  • Dependable intonation up and down the neck

Offer applies only to single-receipt qualifying purchases. Select manufacturers may require that only the manufacturer’s products qualify towards the minimum purchase amount needed to be eligible for promotional financing. Otherwise, an invoice that meets the minimum purchase amount and contains at least one qualifying manufacturer product is eligible for promotional financing. No interest will be charged on promo purchase balance, and equal monthly payments are required on promo purchase until it is paid in full. The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases. New Accounts as of 07/31/2025: Purchase APR is 34.99%. Penalty APR is 39.99%. Min Interest Charge is $2. Existing cardholders: See your credit card agreement terms. Subject to credit approval.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
