BluGuitar Accuses Blackstar of Design Theft in Amp Showdown
Did Blackstar Amps copy BluGuitar's Amp1 design? BluGuitar founder claims Blackstar's Amped 1 steals core components, including a custom power supply.

BluGuitar founder Thomas Blug has sparked controversy, accusing Blackstar Amps of copying their Amp1 design in the new Amped 1 unit. While both companies offer guitar amps with similar names, the real heat lies in Blug’s claim that Blackstar went beyond mere coincidence.

In a YouTube live stream on The Tone Lounge Podcast, Blug compared the disassembled internals of both amps, highlighting a striking resemblance in critical components.

Specifically, Blug pointed to custom-designed transformers and other elements within the power supply that he believes Blackstar directly copied.

Unique Design

Blug argues that the switched-mode power supply used in the BluGuitar Amp1 is unique and not found elsewhere in guitar amps. He claims Blackstar “stole” this design, a move that could have legal ramifications.

Switched-Mode Power Supply: A New Frontier in Guitar Amps?

Blug acknowledges that switched-mode power supplies are not uncommon in other electronics, but their use in guitar amps was a novel concept when the Amp1 project began in 2010. This innovation may be at the heart of the controversy.
