Description
The EXP170-5SL takes D’Addario’s beloved EXL170-5SL 5-string set and gives it serious staying power. A super-thin layer of EXP Coating is fused to the nickel-plated steel wrap wire before it’s wound onto a hex-shaped core, creating a barrier against grime, sweat, and oxidation without dulling the string underneath.
What you get is a genuinely round-wound feel under your fingers and a bright, booming voice that still sounds like a fresh set — because it stays fresh three to four times longer than an uncoated string would. There’s no rubbery or muted quality here; D’Addario’s EXP process was built to preserve the exact tone and response players expect from the standard XL bass line, just with a much longer usable life.
This set is scaled specifically for super long scale 5-string basses, comfortably covering instruments with a scale length up to 38 inches. Every string is manufactured in the U.S.A. on D’Addario’s precision, digitally-controlled winding equipment, so tension and tone stay consistent set after set.
- Coated edition of D’Addario’s top-selling 5-string super long scale bass set
- EXP-coated nickel-plated steel wrap for a bright tone and roughly 4x longer life
- Designed for super long scale basses, up to 38-inch scale length
- Made in the U.S.A.
- Gauges: .045, .065, .080, .100, .130 (wound)
An easy way to extend string life on a super long scale 5-string without giving up the classic D’Addario XL sound.
