Two-Rock reveals compact yet powerful Studio Overdrive amplifier head.]

NAMM 2026: California’s Two-Rock Amplifiers has the Studio Overdrive head, and it’s a compact tube amp designed to be “authoritative and dimensional” even at lower volumes.

The firm is built upon a small but skilled team of tone enthusiasts, with co-owner Eli Lester once declaring that he personally tests every one of its builds before they leave the shop.

As such, Two-Rock has established itself for its high-headroom craftsmanship, and the head version of the Studio Overdrive is the latest to pass Lester’s rigorous QC-ing. This time, though, it’s coming in hotter, with one of the firm’s most gain-heavy builds.

On the surface, the small, two-channel amp may look a little unassuming with its simple control panel – featuring independent Gain dials, a three-band EQ, Master, and Presence, and a quintet of mini switches – the magic lies underneath.

As for the aforementioned mini-switches, while they’re subtle in nature, they’re certainly handy to have. Bright gives a little more, well, brightness and twang with warmer humbucker guitars in mind. Mid and Bass do likewise, injecting just a little bit more of each without needing to push the EQ.

It’s designed, in part, to be an introductory amp for those yet to dive into the Two-Rock world, as a “do all” version of what the Californians offer. Figure out how its stone stack works here, it says, and you’ve got the keys to the entire Two-Rock kingdom.

“The Studio Overdrive is intentionally straightforward and highly touch-responsive, built to reward nuance and control,” says Two-Rock. “It feels fast under the fingers and confident in any setting, from controlled studio environments to the stage.”
