Best guitar strings for metal: Buyer’s Advice
One of the first things you’ll need to contemplate when selecting the best guitar strings for metal is the gauge of string. Using a standard set of strings and then down-tuning can result in the dreaded string flap, whereby the string isn’t thick enough to maintain the correct tension.
This means you get a string that goes out of tune when you press down too hard on it and that’s not what you or your audience want to hear. If you’re going to be down-tuning to drop D, then you can probably get away with a set of 9s, but 10s would be better. For anything a step-down or below, you’re going to want at least a set of 10s or 11s. Also, it’s important to note the scale length of your guitar. A Les Paul-style guitar has a shorter scale length than a Strat-style guitar, and this means a set of 10s on an LP will feel like a set of 9s on a Stratocaster, so worth bearing in mind when purchasing a set of strings to play down-tuned metal.
Once you’ve selected your string gauge, it’s not enough to just slap them on and start down tuning. When you change the gauge of your strings, you’ll also need to adjust the setup. A string that’s thicker can cause multiple issues with your guitar, the most common will be buzz from the string not having enough clearance from the frets. The solution to this is to raise the action to compensate for the thicker string. You may also find the string doesn’t sit in the nut properly thanks to its larger circumference.
Nut issues are a common gremlin that can often fly under the radar. Issues at the nut can cause tuning instability and fret buzz, most often due to the string not sitting properly. When you next pop a set of heavy gauge strings on your guitar, make certain to check they’re sitting in the nut nicely, ideally they should be half in and half out, with no side to side movement.
The material is a crucial component of how guitar strings sound. While metal guitars are all about the heavy, you need to make sure you’ve got the clarity to go with it. This is especially true with extended range guitars and down tuning of regular instruments. Without clarity of tone, your guitar tone will be muddy so a set of flatwound nylon strings won’t do the job here. You’ll want nickel, steel or cobalt sets to make certain you’ve got the higher range harmonic content to go with the crushing heaviness.
