Two-Rock has since developed a range of its own designs, generally focusing on clean, high-wattage amps similar to Fender's amps in the 1950s and 1960s.<ref name="Dickson">{{cite web |last1=Dickson |first1=Jamie |title=Two-Rock Amplification: the tonal approach and philosophy behind the company's sought-after sound |url=https://www.guitarworld.com/features/two-rock-amplification |website=guitarworld.com |publisher=Guitar World |access-date=30 December 2025}}</ref> The company's amps are mostly aimed at—and priced for—the top of the pro market.<ref name="Cardiff"/>
In 2010, Two-Rock was sold to Premier Builders Guild, which purchased multiple amplifier companies, but Premier struggled and closed in 2016. Long-time Two-Rock enthusiast Eli Lester purchased the brand with Mac Skinner, who had been running its operations as general manager since 2004. The two discarded all the existing inventory and brought back co-founder Krinard to help design new models.<ref name="Kobylensky"/> Lester's goal was to "make the biggest, most three-dimensional, clean amplifier you can." Most of Two-Rock's models are 100 watts, including their Classic Reverb Signature and Bloomfield Drive models.<ref name="Kobylensky"/>
With only 25 employees (as of 2025), Two-Rock has declined offers from large retailers to carry their products, with Lester and Skinner preferring to keep the company small. The same team also produces amplifiers for the brand Divided by 13, which Lester and Skinner purchased from the company's founder, Fred Taccone, in 2024.<ref name="Kobylensky"/><ref name="Koe">{{cite web |last1=Koe |first1=Crystal |title="This opportunity sounded too inspiring for us not to explore": Two-Rock acquires Divided by 13 |url=https://guitar.com/news/industry-news/this-opportunity-sounded-too-inspiring-for-us-not-to-explore-two-rock-acquires-divided-by-13-amplifiers/ |website=guitar.com |publisher=Guitar Magazine |access-date=30 December 2025}}</ref>
