GAMECHANGER AUDIO was started in 2015 by Ilja Krumins, Kristaps Kalva, Martins Melkis and Didzis Dubovskis. Their first project was to create a sustain and sostenuto pedal for all musical instruments. The first prototype of the PLUS Pedal was completed in December 2016. The following year, the PLUS Pedal was brought to life through a successful crowdfunding campaign, and it became widely available in 2018. Their next project was the revolutionary PLASMA Pedal. The PLASMA was also successfully crowdfunded, and manufacturing began in the Autumn of 2018. Since then, they have gone on to develop the MOTOR Synth, the LIGHT Pedal, three additional variations on the PLASMA Tube circuit, and most recently the BIGSBY Pedal. Their research and manufacturing base is in Riga, Latvia.

Analog Alien is a boutique guitar effects company established in 2010 by brothers Joe and Jack Napoli (Cloud 9 Recording Inc.). They got started in effects pedal building through first modifying some of the large collection of effects pedals owned by their Cloud 9 Studio, and then offering mods for other guitarists. Jack then decided to have a go at building pedals from scratch, learning from books and by trial & error. He made several prototypes until he felt confident that he had a pedal that most guitar players would want to have in their collection, even if they didn't really have a pedal collection. He tested the circuit using several different guitars and amps until he was satisfied with the results. He also let other guitarists use it but never said that he made it. Soon his overdrive/fuzz face pedal became the pedal of choice for a lot of guitarists that were recording in the studio.

Damage Control Engineering was founded in 2004 by Pete Celi, Gregg Stock and Dave Fruehling, their first products were a line of tube-driven effects pedals. In 2009 they began to develop effects under the Strymon brand name. With models like the OB.1, a simple clean compressor and boost, and the Lex, a small power-house rotary pedal, to BigSky reverb and Timeline delay, Strymon has established itself as a leading guitar effects brand.
