The Ernie Ball Mammoth Slinky Nickel Wound 5-String Bass Strings in 55-145 gauge are built for players who need their low end to mean something. Whether you're tuning down, playing heavy, or just tired of strings that feel like they're barely holding on under a hard attack, this set gives you something to push against. The extra tension isn't just about feel — it's about control. Notes stay focused, the B string actually behaves, and you can dig in without everything turning to mush. Nickel-plated steel wrap over a hex-shaped steel core is a tried-and-true combination for good reason. The hex core grips the winding tightly, which means consistent intonation and tuning stability that holds up through a full rehearsal or a sweaty live set. Tonally, you're getting brightness without harshness — there's a clarity across the full range that keeps the low strings from getting lost in a dense mix. The 55 gauge on the G-string still feels articulate and responsive, while the 145 on the B sits firm and authoritative rather than floppy and vague. These are the strings for the bassist who plays in a band that's loud, tunes low, and needs their instrument to keep up. Drop tunings, extended-range riffing, aggressive fingerstyle — the Mammoth Slinkys are at home in all of it. It's the kind of string set that makes you realize how much tension you were missing, and you probably won't want to go back. **Specifications:** - Product Code: P02823 - String Type: 5-String Electric Bass Strings - Set Name: Mammoth Slinky Bass 5 - Material: Nickel-Plated Steel Wrap - Core: Hex-Shaped Steel Core - Gauge: 55-145 - Number of Strings: 5
