Boss PX-1 Plugout FX: One Pedal, Endless Classics


Boss takes a bold step forward with the PX-1 Plugout FX, a compact stompbox that houses 16 of their classic effects in a single chassis. You get eight preloaded models—including OD-1, DS-1, CE-2, and DD-2—with the flexibility to load an additional eight user slots via the Boss Effect Loader app.

How It Works

The PX-1 isn’t a multi-effect unit in the traditional sense—it delivers one model at a time. A dedicated DSP engine faithfully recreates the tone and dynamic response of each original pedal. To switch sounds, you use the app over USB-C or Bluetooth, selecting from both onboard presets and additional downloadable models, streamlining setup and travel.

Control & Connectivity

A three-knob interface gives intuitive real-time control over parameters (e.g., level, tone, and effect depth), while essential utility is supported through Tap Tempo, MIDI clock synchronization for time-based effects, and an expression pedal input for live modulation. Despite its versatility, it keeps to the sleek, pedalboard-friendly form factor musicians expect from Boss.

Why It Matters

The PX-1 offers tremendous flexibility—one pedal can stand in for many, simplifying rigs without sacrificing tone. Whether for live performance, practice, or recording, it gives players quick access to beloved effects while offering room for future updates. For engineers and guitarists needing agile sound options without a bulky board, it’s a smart leap forward in effects design.
