Fmpedals is an Indonesian boutique guitar effects pedal builder founded by Sylvanus "Ivan" Hardiyanto, who began handbuilding pedals in 2016 from his base in Bekasi, West Java. The brand began as a personal project after Ivan found commercial boutique pedals out of reach, and has grown into an export operation shipping to Australia, China, Germany, Japan, Malaysia, Singapore, Timor Leste, and the United States.

The lineup leans heavily on Indonesian cultural identity, with pedals named after mythological figures and local references. Notable models include the Barong heavy distortion, the Arjuna overdrive, and the Arwana fuzz distortion, alongside an AR Overdrive signature pedal developed with Andra Ramadhan of the Indonesian rock band Dewa 19. Fmpedals uses imported components and positions itself in an accessible price tier relative to other boutique builders.
