Review: Great strings by Daddario as always (bright and clear sound with easy to bend top strings and tight bottom strings) - Great strings to brighten up a dark/warm sounding guitar (Mahogany and Rosewood). Good value for money and in sealed packet. Perfect for having loose top strings for easy bends and tighter bottom strings for drop tuning, that and stops the strings from fluctuating about so much (causing fret buzz and intonation problems. If you use something like 9-46s usually then you will probably have to adjust the guitar slightly (slight truss rod & Intonation adjustment) and maybe heighten action on lower strings. I use these in half a step down Eb tuning sometimes tuning the Eb to Db also have them on another guitar in standard tuning, feels tighter but i prefer it as it doesn't allow the string to warble and fluctuate meaning less string buzz and better response. Review: Makes a Strat sound more stratty - These strings are absolutely amazing. They make a Strat sound more stratty, and springy. Brilliant tone that cuts through without sounding thin. Well done D'Addario. I have used standard d'Addario for 30 years, but these are the most significant uplift in tone that I've always yearned for. I wished I'd discovered them sooner. I also have 2 sets of the NYXL variety but haven't tried them out yet. ## Features - BRIGHTEST STRING - D’Addario’s brightest electric guitar string. - CUT THROUGH THE MIX - Stainless steel wrap wire produces enhanced interaction with magnetic pickups, creating an extraordinarily bright tone that will cut through any mix. - HEX-CORE - Like all D’Addario electric guitar strings, XL ProSteels are made with our proprietary Hex-Core, ensuring perfect intonation, consistent feel, and reliable durability. - EARN REWARD POINTS - XL ProSteels sets have a code on the recyclable VCI bag, which you can register to earn Players Circle points. - MADE IN THE USA – D’Addario electric guitar strings are made in the USA—drawn to our exacting specifications at our New York production facility. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003N1RU5Q | | Best Sellers Rank | 2,859 in Musical Instruments & DJ ( See Top 100 in Musical Instruments & DJ ) 144 in Guitar Strings | | Body Material Type | Steel | | Brand Name | D'Addario | | Coating Description | uncoated | | Colour | Stainless Steel | | Country of Origin | USA | | Customer Reviews | 4.5 4.5 out of 5 stars (3,976) | | Finish Type | Uncoated | | Global Trade Identification Number | 00019954953973 | | Included Components | Guitar Strings | | Instrument | Electric Guitar | | Manufacturer | D'Addario | | Manufacturer Part Number | EPS520 | | Material Type | Steel | | Model Name | EPS520 | | Model Number | EPS520 | | Recommended Uses For Product | playing electric guitar | | Set Name | ProSteels | | String Gauge | Extra Light | | String Material Type | Alloy Steel | | UPC | 019954953973 | ## Product Details - **Brand:** D'Addario - **Colour:** Stainless Steel - **Instrument:** Electric Guitar - **String gauge:** Extra Light - **String material type:** Alloy Steel ## Images ![Guitar Strings - ProSteels Electric Guitar Strings - Round Wound - Brighter, Crunchier, Increased Sustain - EPS520 - Super Light, 9-42 - Image 1](https://m.media-amazon.com/images/I/71FCs7WIfaL.jpg) ## Available Options This product comes in different **Pattern, Size, Style** options. ## Questions & Answers **Q: Do the super light 9-42 have a wound or unwound 3rd string?** A: Hi The 3rd ( 016 ) string is plain steel, not wound. **Q: will they fit on my strat?** A: They fitted mine ok.
