In a recent interview with LaughingMonkeyMusic, Testament’s Alex Skolnick reflected on the distinctiveness of the original US thrash metal sound and why many contemporary metal bands tend to sound alike.
Skolnick attributed the individuality of early thrash metal guitarists to the limited gear options available at the time. This scarcity pushed musicians to develop unique playing styles. In contrast, he observed that modern bands often rely on similar equipment, resulting in a more homogenous sound.
This mainstream success of Metallica also highlighted the diversity within the US thrash metal scene. Each band had its own distinct characteristics, even though they shared the same genre. Skolnick reflected "each band was affected by several things", noting how thrash vocalists like his bandmate Chuck Billy, Metallica's James Hetfield, and Megadeth's Dave Mustaine each had unique vocal styles.
"The tone was very hard to get at that time… There's a positive side and a negative side to it. On the negative side, it was much more difficult. You had to work much harder. Most of the amps were designed for '70s rock. They sounded like they would be good for Lynyrd Skynyrd. And then, fast forward a number of years, and that tone gets popular. And there are even multi-million-selling albums that have had this tone. Well, amp manufacturers had no choice but to make amps that could sound crunchy. Now, it's easy," Skolnick explained.
He elaborated on how this lack of gear diversity fostered individuality among musicians: "The positive side was that you were forced to be individual, and people didn't sound the same. Now, you have a lot more groups that sound very similar, and you could tell, 'Oh, they're using this exact same plugin…' I could point to about half a dozen very popular groups that sell a lot of tickets… and it sounds so similar."
Skolnick concluded by emphasizing the value of the challenging conditions under which thrash metal developed: "I think it helped having emerged during the time where you really had to be a scavenger, and compile a bunch of mismatched gear and amps and pedals, and somehow try to make it sound like that."
