The Boss PX-1 is a convertible multi-effect pedal that holds multiple authentic recreations of effects from the BOSS compact pedal lineup. The PX-1 Plugout FX is an innovative hardware platform that captures the timeless BOSS compact pedal experience in one versatile pedal. This convertible stomp holds multiple authentic effect recreations from the historic BOSS lineup, providing endless fuel for every creative journey. 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, 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, supported by an onboard display for current parameters and internal settings. The PX-1 supports external control with one or two footswitches or an expression pedal, offers stereo I/O, tap tempo, and MIDI clock sync. The permanent library features eight famous BOSS pedals, including the OD-1 Over Drive, SP-1 Spectrum, and PH-1 Phaser. The PX-1's Swap function lets you switch between two effects, and nearly any parameter can be assigned for real-time expressive control while performing.
