Description
If you’ve ever loved a fresh set of classical strings for exactly one glorious week before they went dull, EXP45 is the fix. D’Addario takes their best-selling Pro-Arte classical formula — laser-sorted clear nylon trebles paired with silver-plated copper basses — and seals the wrap wire in an ultra-thin EXP coating before it’s even wound onto the multi-filament core.
- Normal tension set, clear nylon trebles, non-ball end basses
- Silver-plated copper wrap wire, EXP coated, wound over multi-filament core
- Laser-sorted Pro-Arte trebles for consistent intonation string to string
- Retains that bright, round-wound “new string” feel 3-4x longer than uncoated sets
- Corrosion-resistant packaging keeps them fresh until you break the seal
- Designed, engineered and made in the USA to D’Addario’s tightest tolerances
What actually changes day to day: your fingers stay cleaner, the grime that usually builds up on wound strings has nowhere to grab onto, and the tone stays warm and projecting instead of going thuddy and flat. It’s the same balanced, comfortable-feeling set that’s become D’Addario’s top classical seller — just built to outlast the usual restring cycle by a wide margin.
If you gig, teach, or just hate that slow fade from fresh to lifeless, EXP45 buys you serious time between changes without asking you to compromise on tone.
