GFI System

In the current JustPedals catalogue, GFI System is represented by Delay & Reverb Pedals, Reverb Pedals and EQ Pedals. Current listings include Skylar Reverb, Rossie Multi-Filter and s ENIEQMA Dual Channel EQ. That makes the range relevant to players looking for time-based effects and ambience, plus modulation and movement. Check each model for its exact circuit or processing platform, controls, power requirements and connections, particularly where the catalogue includes both pedals and supporting gear.

Modulation Pedals

Modulation pedals vary pitch, time, amplitude or phase to create movement around the dry sound. Chorus, flanger, phaser, tremolo, vibrato and rotary-style effects all sit in this broad group, but their controls and signal behaviour differ. Rate sets speed; depth, feedback, waveform, mix and stereo routing determine intensity and space. Decide whether the pedal should sit before or after drive and ambience, then check headroom, tap or MIDI control, mono compatibility and whether the effect leaves the dry signal intact.

Digital

Digital products use conversion and processing to create, store or control the effect. This can provide presets, complex routing, repeatable algorithms, USB, MIDI and firmware features, but conversion, latency, power requirements and clocking depend on the design. Check the input and output levels, sample or impulse-response support, bypass behaviour and current draw when combining a digital unit with analogue pedals or a direct recording setup.

MIDI

MIDI sends, receives or responds to Musical Instrument Digital Interface messages rather than carrying instrument audio itself. Program changes can recall presets, continuous controllers can move parameters and MIDI clock or transport messages can synchronise timing. Check the connector or USB method, channel and message support, clock direction, latency and whether the device needs a separate MIDI host or adapter. MIDI control is powerful, but compatibility depends on the exact messages each product understands.

Presets

Preset-capable products can store and recall effect settings, signal paths or control assignments. The useful differences are the number of locations, whether footswitches or MIDI can recall them, what parameters are saved, how quickly they change and whether trails continue between settings. Check editing, backup, firmware, expression and USB requirements, and confirm that the preset system covers the parameters you need rather than assuming every control is recalled.

Stereo

Stereo products provide separate left and right audio paths, which may widen modulation, preserve independent delays or route a pedalboard into two amplifiers or a mixer. Input and output behaviour is not always symmetrical: some units sum a stereo input, while others create stereo from a mono source. Check whether the effect collapses safely to mono, how the dry signal is routed, the socket format and the destination’s panning and phase requirements.
