Scientific Anglers Amplitude Textured Anadro Nymph
The first series of lines to feature the revolutionary AST PLUS slickness additive, the Amplitude will shoot farther and last longer than any other line on the market. It’s slickness down to a science.
If you’re anything like us, the allure of big fish and big rivers is intoxicating. That’s precisely why we created the Amplitude Anadro. Designed with line control in mind, its extended rear taper allows you to cast a mile, mend with authority, and turn over nearly any rig imaginable—from dredging double nymphs to larger dry-dropper concoctions. Steelhead, salmon, and trout won’t know what hit them.

FAQ
What makes the AST PLUS additive different from other line technologies?
The AST PLUS additive provides enhanced shooting performance and improved durability compared to standard lines, allowing for longer casts and better line retention in water.
Is the Amplitude line suitable for dry-dropper setups?
Yes, the extended rear taper allows for effective use in dry-dropper rigs, including larger configurations with double nymphs or other weighted combinations.
How does the line perform in windy or long-distance casting conditions?
The slickness and controlled taper help maintain line integrity and reduce drag, making it effective for casting a mile or more with consistent mending.

I’ve used this line on several long stretches of river and it casts much farther than my previous line. The mending is smooth and I can handle heavy rigs without tangles. Great for steelhead season.
Lisa McDonald –
The AST Plus additive really makes a difference in how it shoots. I can cast a mile with ease and the line holds up well in cold water. A bit more expensive, but worth it for the performance.
Julian Bond –
Used it for a dry-dropper setup on a salmon run. The line stayed intact and allowed me to mend properly. The texture and control are excellent for precise presentations.
Adrian Mills –
Felt more durable than other lines I’ve tried. Casts well in windy conditions and doesn’t snag easily. Good for both nymphing and larger rigs.
