A Universe of Musical Colors

Since 1977, BOSS compact pedals have inspired generations of musicians around the world. Over 140 unique models have been produced, over 19 million units have been sold, and many have remained in non-stop production for decades. From vintage classics and go-to workhorses to rare and specialty effects, the PX-1 puts the diverse BOSS compact pedal range at your command.

Authentic Recreations

Backed by newly developed BOSS algorithms, each effect in the PX-1 delivers the authentic sound and response of the pedal it’s based on. Every detail is modeled with stunning accuracy, thanks to a powerful DSP engine dedicated to recreating the sound of a single effect at a time. Dial in tones fast with the familiar knob interface you’re used to with BOSS compacts, supported by an onboard display for current parameters and internal settings.

Modern Flexibility

The PX-1 supports external control with one or two footswitches or an expression pedal. Use the Swap function to switch between two effects. Or assign nearly any parameter for real-time expressive control while performing. Stereo I/O provides flexible connectivity and enhanced sound for models that support stereo operation, while tap tempo and MIDI clock sync help you get the most out of time-based effects.

Core Effects

The PX-1’s permanent library features eight famous BOSS pedals, including the three models from the 1977 debut and iconic drive pedals like the DS-1 and SD-1. Every model has a “1” designation, indicating that it’s the first of its type within the BOSS timeline.

OD-1 Over Drive

The OD-1 invented the now ubiquitous “overdrive” category in stompbox effects. Designed with an asymmetrical clipping circuit that reproduces the pleasing sound of a driven tube amp, this yellow classic dishes up warm, fat tones rich with even-order harmonics.

SP-1 Spectrum

This unique and rare BOSS effect boosts a single frequency band determined by the Spectrum control. It’s great for many tone-shaping applications, such as adding presence to solo lines, boosting the character of overdrive and distortion pedals, and creating nasal “cocked wah” lead tones.

PH-1 Phaser

The PH-1 produces a mild phaser sound with a full low-end response. Skillful engineering allows you to dial in a range of musical tones with a simple two-knob interface.

SG-1 Slow Gear

This well-loved BOSS original reshapes the note attack to create violin-like swell tones. The SG-1 is particularly effective when crafting ambient sounds with delays and reverbs.

CS-1 Compression Sustainer

The first BOSS compressor pedal has a distinctly different circuit than the later CS-2 and CS-3 models. It features an optical design with a photocoupler, which offers a slower attack with a unique character.

TW-1 T Wah

The TW-1 provides a classic wah effect that’s controlled by the input signal level. Two controls adjust the sensitivity and depth of the input filter.

SD-1 SUPER OverDrive

The workhorse SD-1 has been the core gain pedal for generations of players across every musical genre. Expanding on the OD-1 design with enhanced voicing and a tone control, this essential stomp is packed with highly musical overdrive colors.

DS-1 Distortion

The DS-1 is the top-selling BOSS compact pedal ever. Its original, unchanged design delivers a hard-edged attack and smooth sustain, making it a player’s staple for nearly four decades.

Eight Additional Effects

The following eight effects are also included with the PX-1, and you can load them into the pedal’s eight user locations. After registering your pedal with a free Roland Account, download the effects into the PX-1 using the BOSS Effect Loader app.

CE-2 Chorus

The CE-2 distilled the sound of the CE-1 Chorus Ensemble—the first BOSS pedal and the world’s first chorus effect—into the smaller compact pedal format. Tuned for mono operation and a lighter modulation sound than the CE-1, this signature BOSS original has defined the guitar tones on countless hits from the 1980s to the present day.

BF-2 Flanger

In production for over 20 years, the original BF-2 hardware featured a unique analog design based around a single BBD chip. This versatile effect produces an array of warm modulated tones, from metallic and phase-shifted textures to soft chorus and wavering vibrato.

PN-2 Tremolo/Pan

The PN-2 combines tremolo and panning effects in one design. Tremolo mode produces a tighter amplitude modulation effect than traditional circuits, while Pan mode moves the audio signal across the stereo field. Triangle and square wave shapes are available for different sound characteristics.

OC-2 Octave

The original OC-2 hardware was a pioneer in octave pedals, producing touch-responsive tones with an all-analog circuit and a unique method of phase inversion. The OC-2 works great for adding mono octave sounds to any instrument, and it’s legendary among bassists for its ability to create synth-like sub-bass tones.

PS-2 Digital Pitch Shifter/Delay

The PS-2 brought continuous pitch shifting to the compact pedal format in 1987, and the effect remains popular for its retro 8-bit processing and vintage digital character. Three pitch modes include a manual option for fine-tuning the pitch over two octaves and presets for one octave up and one octave down. The PS-2 also includes three delay modes with time ranges from 30 ms to two full seconds.

VB-2 Vibrato

This underground BOSS classic produces warm, characterful tones with mild pitch fluctuations and dynamic control of the modulation onset with the Rise Time function. In addition to standard toggle operation for the pedal switch, a special Unlatch mode adds the effect only when holding the switch.

DD-2 Digital Delay

Released in 1983, the DD-2 hardware was the world’s first digital delay in stompbox form. Created in the early days of digital music technology, the DD-2 is still loved for its warm 12-bit tones that sit perfectly in the mix.

DF-2 SUPER Feedbacker & Distortion

Compared with the DS-1 Distortion, the DF-2 offers higher gain and a smoother attack character. Its secret weapon is the feedbacker function, which lets you enjoy the sustained harmonic feedback of a cranked amp at any volume, including practice sessions with headphones. Hold the pedal switch or an external footswitch to punctuate performances with this expressive tone as you play.

An Ever-Expanding Universe

Add more effects with Model Pass purchases within the BOSS Effect Loader app. New effects can be loaded into the pedal’s eight user locations, and many effects will be added over time.

Learn About Model Passes and Upcoming Effect Releases

PW-2 Power Driver

The PW-2 delivers gritty, rough-grained distortion that works in many musical settings. Combine with a high‑gain amp for a wall of sound, or use a lower-gain setup for refined crunch. Start with the Fat and Muscle controls at minimum, then raise them for the desired low and mid-frequency character.

XT-2 Xtortion

The XT-2 is designed for bold distortion with maximum tone shaping. Even with the cleanest amps, it produces thick, solid gain with a commanding presence. Contour and Punch unlock a huge range of midrange control. Create massive tones with scooped mids for heavy riffs. Or boost focus and trim girth to slice through dense mixes.

CS-2 Compression Sustainer

While the CS-1 used an optical detector circuit, the next-generation CS-2 introduced a VCA for faster response. The compression is more versatile, enhanced by subtle distortion in the VCA circuitry that adds natural richness and character. Use the Attack knob to adjust the response to suit your personal touch and different music styles.

DM-2 Delay

A longtime player’s favorite, the DM-2 was the first BOSS analog delay in the compact pedal lineup. Its retro BBD circuit produces lush delays that become more saturated with each repeat, creating organic ambience that blends beautifully with the unprocessed sound. Turning up the Intensity knob drives the effect into gritty self-oscillation for expressive textures.

OD-2 TURBO OverDrive

The OD-2 is a highly versatile overdrive pedal with two distinctly different sounds. The standard mode produces a mild, well-defined overdrive with a sweeter character than the OD-1. Switching on Turbo mode activates an independent drive circuit with higher gain and increased presence, ideal for playing heavy riffs and solos.

DC-2 Dimension C

The DC-2 was born by adapting the rack-based Roland SDD-320 Dimension D into a compact pedal for guitars and other mono instruments. While it adds depth and spaciousness like a chorus, the unique Dimension effect produces minimal modulation, creating a three-dimensional character while preserving the instrument’s natural tone.
