“This monumental collaboration signals a new chapter in Bad Cat’s commitment to exceptional tone”: Bad Cat marks the return of amp design guru Mark Sampson with the Era 30

NAMM 2025: Bad Cat has announced the welcome return of respected amp designer Mark Sampson – best known as the man who founded Matchless and the design brains behind the brand’s early models – heralding his arrival with a new two-channel tube amp, the Era 30.

“Mark Sampson, renowned for his pioneering work in boutique amplifier design, was instrumental in shaping the golden age of hand-wired tube amps,” says Bad Cat.

“His original designs set a benchmark for tone, craftsmanship, and reliability. Now, with the Era 30, Sampson has distilled over 35 years of amplifier design evolution into a product that embodies the best of his creative vision.”

The Era 30 channels Sampson’s early love of British amps into a head featuring two fully independent channels.

The first channel features an EF86 tube in the preamp, which is a higher-gain tube favored in the likes of early Vox builds (think Shadows, not Beatles) and favored for its full frequency response and sensitivity.

The second channel uses a trio of 12AX7 tubes in the preamp stage and there’s a quartet of EL84 power tubes onboard, plus a 5AR4 rectifier tube.

It’s a combination that oozes flexibility and boutique class and there’s a wealth of other smart appointments on the spec, including independent input gain controls, a six-position Depth control, and a fully bypassable buffered effects loop.

Then there are independent channel volumes and a global master volume control – a post phase-inverter circuit that allows you to keep all of that power amp saturation, but wield it at volumes more suited for home and recording applications.

And, in true boutique style, all the of Era 30s are hand-wired in Bad Cat’s facility in Costa Mesa, CA.

The Era 30 is a testament to his legacy and our shared commitment to delivering the ultimate tone experience.”

“I’m not ready to give it up yet,” summarises Sampson, in the clip above. “The best stuff is still coming.”
