gfi system guitar effect pedals

GFI System pedals are designed and assembled in Indonesia by Henry Widjaja with help from a small team of engineers and techies, including his long-time friend Yonas Darja and Yonas’ brother Jesse.

GFI started out in 2010 designing and building analog pedals and began taking the plunge into the realm of digital design by 2013.

GFI’s goal is to market innovative and exciting products that capture the hearts and imaginations of guitar players and musicians for many years to come.

History (in Henry’s words)

Yonas and I were already toying with the idea of starting a guitar-oriented tech company while we were studying in the U.S. back in 2003.  The two of us spent more time talking & obsessing about guitars, effects, and music than we did studying for our exams!  

My major was Electrical Engineering with specialization in Signal Processing, and my hobby was tearing pedals apart to learn how they worked – this combination was essential to forming my knowledge base of how sound was created.

However, our idea for an audio company took a back seat after graduation. We went back to Indonesia, worked 9-to-5 jobs and started families of our own.   I went to work for an engineering company and then moved on to teach electrical engineering at a university.   All along, our little dream never left my mind; I still loved to tinker with pedals & electronics. 

While I've enjoyed working in an academic environment, I soon realized that I enjoyed my other activity much more, and so I took the plunge!  I quit my job, bought an oscilloscope, a soldering station, a drill press, a big desk, and a whole bunch of parts – and thus GFI System was born.

    • Tap-tempo (with 4 sub-divisions)
    • Kill-Dry function
    • Analog dry-thru

    Specular Tempus is a powerful reverb and delay effect processor in a compact pedal. Featuring 32 hand-crafted algorithms, 8 presets. stereo in/out, tap-tempo, and extensive inter-connectivity. Using the SpecLab software (free download) users get access to an extended set of parameters for deep-editing of the algorithms.

    Preset System:
     the 8 presets are organized in 4 banks, each bank contains 2 patches: A and B.

    Stereo I/Oa reverb and delay effect processor sounds much much better in stereo, period.

    Interconnectivity : Specular Tempus has been designed with the need to interconnect with the outside world in mind. It features no less than 4 interfaces that greatly expand the specular horizon :

    • Aux-In - accepts single, dual, or triple buttons switch boxes for versatile external control (tap-tempo, bank up/down, etc).
    • Aux-Out - provides a switch contact that you can use to control other gears  (e.g. switching an amp's channel).   
    • Effects Loop - create your own unique delay or reverb sounds by inserting other effects into the delay or reverb feedback.
    • MIDI In - nearly all functions of the pedal are opened to MIDI access, including tap-tempo and expression pedal control.

    Tap-Tempo : you can tap in your tempo using an external tap pedal or on the pedal itself (using a special mode). Subdivisions can be specified uniquely for each preset.

    Auto knob swell : when you engage this feature, the parameter controlled by one of the knob is slowly swept to the maximum value, hold it there, and then swept back to the original setting. Used judiciously, this feature can introduce dynamic elements to the soundscape. 

    Analog Dry-thru : dry signals are routed through pure analog paths.

    Small form-factor : the pedal measures 12 x 9 (cm) or 4.7 x 3.5 (inch).
