Bad Cat Amps

Bad Cat was founded in 1999 by James Heidrich, who saw a specific gap: Matchless had just closed, and the boutique amp market it had created was suddenly without its flagship brand. Heidrich approached Mark Sampson in the summer of 2000 to design circuits for the new company — bringing Matchless's chief designer directly into Bad Cat's DNA. The first amps, the Black Cat and Cub, debuted at NAMM 2000 and were explicitly in the lineage of the DC-30 and Lightning. The Hot Cat followed in 2002 — a 30-watt class A design that could keep pace with 50-watt amps and introduced a level of gain that class A circuits weren't previously associated with. It won nearly every industry award available.

Sampson's departure from Bad Cat around 2003–2004 was less than amicable. Heidrich continued building the brand to the same point-to-point, premium-component standard until selling it in 2011. He later founded Blackwing Amplifiers in 2016, building to the same standards with the same team. Both Heidrich and Sampson died in 2025 — Heidrich earlier in the year, Sampson on February 27th, just weeks after unveiling the Era 30 at NAMM, his first Bad Cat design in over two decades.

The thread back to this collection's core runs through Sampson himself: as a teenager in Mason City, Iowa, he built a plywood collage of the Beatles on stage, complete with Rickenbacker guitars and Vox amps. His career was a decades-long attempt to understand and replicate what those instruments did. The Matchless page on this site documents where he started. Bad Cat is where some of that understanding ended up.
