Description
EXP45 is D’Addario’s most sought-after classical guitar set, prized by players for its dependable balance of warmth, playing comfort, and clear projection. This normal tension set belongs to the celebrated Pro-Arte line, whose treble strings are laser-sorted for exceptional consistency string to string.
What sets EXP45 apart is D’Addario’s EXP Coating process. A microscopically thin protective layer is bonded directly to the silver-plated copper wrap wire before it’s wound around a multi-filament core. This barrier fends off the corrosion and grime that typically dull a string’s voice over time, so these strings hold onto their bright, articulate “new string” character far longer than uncoated alternatives — roughly three to four times longer, in fact. Despite the coating, the feel under your fingers remains true to a natural round-wound string, with no artificial slickness.
- Normal tension set for balanced tone and comfortable feel

Backed by D’Addario’s reputation as the world’s largest and most trusted string maker, EXP45 offers classical guitarists a coated string that sounds and plays like a traditional one — just with a much longer lifespan.
