Customer Profile: Two-Rock Amplifiers

Musicians of significant renown—John Mayer, Eric Johnson, Doyle Bramhall, Ariel Posen, David Ryan Harris, Joey Landreth, and Matt Schofield—have adopted Two-Rock amplifiers as core components of their sound. Early designs drew inspiration from classic Fender amplifiers and Alexander Dumble schematics, though the brand has evolved distinctly.

"We really just put the best parts in there we can. We don't even look at the price of anything, we just put the best stuff in there and then price the amp afterward. I might sit there and spend two, three, four weeks just working on one capacitor." —Eli Skinner, Two-Rock Owner

Skinner attributed considerable sonic character to the power supply designed with Pacific Transformer.

"The transformers are a huge deal. We actually have a proprietary transformer manufactured for us—and it does do power scaling." —Eli Skinner

He described the dual primary design, explaining that half-power mode preserves phase and impedance characteristics while providing enhanced responsiveness and dynamic range.

The track 'Slow Dancing in a Burning Room' from John Mayer's concert film 'Where the Light Is' demonstrates the tonal capabilities—from delicate initial phrasing to powerful sustain—that establish Two-Rock's reputation among elite performers.
