The history of Mark L Custom (MLC) Guitar Electronics and Amplifiers dates back to 2002, when Marek Laskowski (Mark L) first decided to design and produce professional guitar systems for musicians. Being a guitarist and guitar-electronics aficionado himself, Mark realized early on that he had the ability to modify existing equipment to make it sound and perform better than originally designed.

​Soon Mark began designing and building his own original equipment under the MLC name that vastly outperformed anything currently on the market. The music business took notice as the list of professional musicians, as well as musical enthusiasts, who choose to utilize MLC equipment continued to grow exponentially since 2002. Today MLC is headquartered in Gdańsk, Poland, and serves hundreds of professional and discerning musicians world wide . Not to rest on his laurels, Mark continues to create new reference grade guitar equipment, designs and assembles innovative guitar rigs, and builds some of the finest tube amplifiers made.
