Description
When you retire a dead set of classical strings and drop on EXP44s, the difference is immediate: crisp trebles, a round, natural feel under the fingers, and a bright “new string” voice that actually sticks around. D’Addario builds these by bonding an ultra-fine EXP coating to silver-plated copper wrap wire, then winding it over a multi-filament core — so the corrosion and grime that usually dull your tone within weeks get blocked before they start. Expect 3-4x the lifespan of uncoated classical strings, without the stiff, muted feel some coated sets suffer from.
EXP44 sits at the top of D’Addario’s tension chart — extra hard — built for players who want serious string resistance and volume without sacrificing tonal clarity. These are part of the Pro-Arte line, so the clear nylon trebles are laser-sorted for tight diameter tolerances, giving you consistent intonation and balance string to string.
- Extra Hard tension, clear nylon trebles, non-ball end
- EXP coating over silver-plated copper basses for a natural roundwound feel
- 3-4x longer tone life than uncoated strings
- Laser-sorted Pro-Arte trebles for accuracy
- Corrosion-resistant packaging keeps the set fresh until you open it
- Designed and manufactured in the USA under strict quality control
If your last set went dull weeks ago, this is the upgrade — same bright attack you had on day one, just lasting much longer.
