Description
The OPFXS Gain Box is a fully analog, multi-channel distortion pedal featuring sophisticated digital control and MIDI integration. Its unique architecture combines three distinct analog distortion stages—Overdrive, Fuzz, and Distortion—alongside a blendable Dry channel for preserving signal clarity. These channels can be mixed in parallel or run in series, allowing for complex gain stacking that remains articulate. The pedal features a global low-pass filter and output level control, both of which are digitally stored in three onboard presets. This design provides the tactile response of analog circuitry with the modern convenience of digital recall and remote control. It is an ideal solution for guitarists seeking a wide variety of gain textures from a single, compact workstation.
