Get a pitch shifter that's as flexible and creative as you are.The BOSS XS-100 Poly Shifter re-imagines pitch control, combining expressive pedal action with advanced polyphonic processing. Built on years of BOSS innovation, it delivers natural tone, accurate tracking, and a wide range of creative options to help you find the sound in your head. The responsive pedal lets you shift smoothly across four octaves up or down, while the toe switch and footswitches give you instant access to bold jumps, drop tunings, capo simulations, or fixed semitone steps. Whether adding dramatic sweeps, subtle doubling, or quick retunes, the XS-100 keeps your playing fluid, musical, and free from the artifacts that plague conventional pitch shifters.The XS-100 offers deep customization and extensive connectivity. You can fine-tune response curves, assign pedal ranges, adjust pitch-change speeds, and save up to 30 memories for instant recall. Independent controls for rise and fall times let you shape expressive effects, while detune modes expand your tonal palette with lush doubling textures. External footswitch and expression pedal support give you additional control, and MIDI I/O makes the XS-100 ready for integration into advanced rigs. With its transparent sound, dynamic response, and versatile routing, the XS-100 presents a deep sonic palette for you to explore, but beware the rabbit hole...Boss XS-100 Poly Shifter FeaturesAdvanced pitch-shifting workstation with deep control options and an eight-octave rangeTotal pitch control for guitar and bassClass-leading pitch shifting quality realized with new BOSS algorithmsClear response and natural feel that retains the fundamental sound characterSmooth onboard pedal with integrated toe switch provides linear pitch control across +/- four octavesFixed pitch settings in semitone steps across eight octaves for drop tunings, capo effects, and otherworldly tonesDetune function (+/- 50 cents) to create rich doubling effectsAdjustable pedal curve and responseFully customizable toe switch and footswitches for momentary pitch changes, instant retuning, and moreClear display for editing sounds and 30 memories for storing favorite setupsDedicated analog output that mirrors the input signalConnect up to two footswitches or an expression pedal for extended controlTRS MIDI I/O for external control and sending MIDI commands with the pedal and footswitchesUSB connector for system updatesBoss XS-100 Poly Shifter SpecificationsAD Conversion24 bits + AF methodAF method (Adaptive Focus method) This is a proprietary method from Roland & BOSS that vastly improves the signal-to-noise (SN) ratio of the AD and DA converters.DA Conversion32 bitsSampling Frequency: 48 kHzMemories: 30Nominal Input Level: INPUT: -10 dBuMaximum Input Level: INPUT: +7 dBuInput Impedance: INPUT: 2.2 MΩNominal Output Level: OUTPUT: -10 dBuMaximum Output Level: OUTPUT: +7 dBuOutput Impedance: OUTPUT: 1 kΩRecommended Load Impedance: OUTPUT: 10 kΩ or greaterBypass: Buffered bypassControlsEFFECT switchTUNE DOWN switchSELECT knobEFFECT buttonMEMORY buttonEXP1 pedalDisplay: Graphic LCD (64 x 32 dots, backlit LCD)ConnectorsINPUT jack: 1/4-inch phone typeTHRU jack: 1/4-inch phone typeOUTPUT jacks: 1/4-inch phone typeCTL1, 2/EXP2 jack: 1/4-inch TRS phone typeUSB port: USB Type-C®MIDI (IN, OUT) connectors: Stereo miniature phone typeDC IN jackPower Supply: AC adaptorCurrent Draw: 160 mAPower consumption when in OFF mode (when the power automatically turns off): 0.1 WAccessoriesAC adaptorLeaflet (“USING THE UNIT SAFELY”, “IMPORTANT NOTES” and “Information”)Rubber foot x 4Options (sold separately)Footswitch: FS-5UDual footswitch: FS-6, FS-7Expression Pedal: EV-30, FV-500L, FV-500H, Roland EV-5MIDI/TRS connecting cable: BMIDI-5-35, BMIDI-1-35, BMIDI-2-35, BCC-1-3535, BCC-2-3535Size and WeightWidth147 mm, 5-13/16 inchesDepth230 mm, 9-1/16 inchesHeight72 mm, 2-7/8 inchesMaximum height96 mm, 3-13/16 inchesWeight1.7kg, 3 lbs 12 oz Boss XS-100 Poly Shifter Pitch Shifter Pedal with Expression Pedal And Display Screen.
