Full Description Compact classics, one box The PX-1 puts a curated library of 16 BOSS icons at your feet, loading one model at a time for a clean, focused signal path that sounds and feels like the originals. Choose your effect and enjoy instant access to proven tones without hauling a whole board of separate pedals Authentic feel, focused DSP Newly developed algorithms run on a powerful processor dedicated to a single effect, so dynamics, sweet spots and knob responses behave just right. The familiar BOSS layout and a clear display make dialling in stage-ready sounds fast, even under low lights Flexible control and connectivity Stereo in/out opens up wide chorus, flanging and panning, while tap tempo and TRS MIDI keep delays and modulations locked to the groove. Add external footswitches or an expression pedal to sweep parameters live, and use Swap to jump between two loaded effects mid-song Expand as you go Grow the palette with additional models via affordable Model Passes in the BOSS Effect Loader app over Bluetooth or USB-C. Power it from the included adaptor or USB, add it to any rig with ease, and gig with confidence thanks to the five-year BOSS warranty Specifications Product Name: BOSS PX-1 Plugout FX Product Code: PX-1 Format: Convertible single-effect pedal platform Operation: Loads one model at a time for a focused signal path Bypass: Buffered bypass Warranty: BOSS five-year warranty Dimensions: 73 (W) x 125 (D) x 56 (H) mm; 2-7/8 (W) x 4-15/16 (D) x 2-1/4 (H) inches Weight (excluding AC adaptor): 400 g; 15 oz Controls: LEFT knob, CENTER knob, RIGHT knob, pedal switch Indicator: CHECK indicator Display: Graphic LCD 128 x 48 dots Bluetooth: GATT profile (MIDI over Bluetooth Low Energy) Editor/app: BOSS Effect Loader via Bluetooth or USB-C Processing: Dedicated DSP per effect for authentic tone and response Sampling frequency: 48 kHz AD conversion: 24 bits + AF method (Adaptive Focus method) AF method note: Proprietary Roland & BOSS technique that markedly improves AD/DA S/N DA conversion: 32 bits Nominal input level: INPUT A (MONO), INPUT B: -20 dBu Maximum input level: INPUT A (MONO), INPUT B: +7 dBu Input impedance: INPUT A (MONO), INPUT B: 1 MΩ Nominal output level: OUTPUT A (MONO), OUTPUT B: -20 dBu Maximum output level: OUTPUT A (MONO), OUTPUT B: +7 dBu Output impedance: OUTPUT A (MONO), OUTPUT B: 1 kΩ Recommended load impedance: OUTPUT A (MONO), OUTPUT B: 10 kΩ or greater Connectors: INPUT A (MONO), INPUT B, OUTPUT A (MONO), OUTPUT B: 1/4-inch phone type; CTL1,2/EXP: 1/4-inch TRS phone type; DC IN; MIDI IN: stereo miniature phone type; USB COMPUTER: USB Type-C Inputs/outputs: Stereo input & stereo output Tap tempo: Supported; MIDI clock sync via TRS MIDI IN External control: Supports 1–2 footswitches or an expression pedal Power supply: AC adaptor or USB bus power Current draw: 260 mA (AC adaptor), 420 mA (USB) Included effects (16): OD-1, SP-1, PH-1, SG-1, CS-1, TW-1, SD-1, DS-1, CE-2, BF-2, PN-2, OC-2, PS-2, VB-2, DD-2, DF-2 Accessories included: AC adaptor; leaflet (“USING THE UNIT SAFELY,” “IMPORTANT NOTES,” “Information”); Roland Cloud Activation Card Options (sold separately): Footswitch: FS-5U; dual footswitch: FS-6, FS-7; expression: FV-500H, FV-500L, EV-30, Roland EV-5; TRS/MIDI cables: BMIDI-5-35, BMIDI-1-35, BMIDI-2-35, BCC-1-3535, BCC-2-3535
