Boss Drops the SY-200 Synth and IR-200 Cab Sim
September 17, 2021 · 7 sources

Boss announced two additions to its 200 series compact pedal line: the SY-200, a synth pedal for guitar and bass, and the IR-200, a pedal-based amp simulator and impulse response loader. The SY-200 carried a launch price of $3291.
The SY-200 built on the earlier SY-1, which Boss described as acclaimed. Boss described the new pedal as "offering a universe of rich, analog-inspired polyphonic tones in a small footprint," and any guitar or bass works through a standard 1/4-inch cable, with no special pickup required2.
"Offering a universe of rich, analog-inspired polyphonic tones in a small footprint, the SY-200 makes it simple to weave"2
The pedal shipped with 171 sounds organized in 12 analog-style synth categories, each tweakable through three dedicated parameter knobs, with 128 memories for saving and recalling setups2.
| Category | What it covers |
|---|---|
| LEAD | Single-note soloing sounds2 |
| PAD | Layered chords2 |
| STRING | String synth tones2 |
| BELL | Bell tones2 |
| ORGAN | Organ with rotary-style modulation2 |
| BASS | Filtered and sub-octave tones2 |
| DUAL, SWEEP, NOISE, SFX, SEQ, ARPEGGIO | Additional categories3 |
Other SY-200 features announced at launch2:
- Two customizable footswitches with press-and-hold operation, assignable to synth on/off, memory scrolling, pitch bend, synth hold, and more25
- Independent level controls for blending synth and normal guitar sounds2
- Selectable modes that globally optimized the synth engine for guitar or bass2
- Full MIDI I/O on 3.5 mm TRS jacks, with cables sold separately2
- Support for up to two external footswitches or an expression pedal2
- Power from a PSA-series AC adaptor or three AA batteries43
The SY-200's MIDI connections use 3.5 mm TRS jacks, and the cables are sold separately, so plan for them if you want MIDI control from day one2.
The IR-200, meanwhile, was announced as a digital amp simulator and IR loader with 32-bit AD/DA conversion, 32-bit floating-point processing, and a 96 kHz sampling rate. Over 150 hi-res cab impulse responses from Boss and Celestion Digital were on board, and 128 user IR slots accepted mono or stereo WAV files at up to 32-bit floating point/96 kHz resolution in 200 or 500 ms lengths6.
| IR-200 specification | Value |
|---|---|
| AD/DA conversion | 32-bit6 |
| Processing | 32-bit floating point6 |
| Sampling rate | 96 kHz6 |
| Onboard cab IRs | Over 150, from Boss and Celestion Digital6 |
| User IR slots | 1286 |
| User IR format | Mono or stereo WAV, up to 32-bit floating point/96 kHz, 200 or 500 ms6 |
| Memories | 1286 |
Each of its amp types carried responsive gain, bass, mid, and treble controls, and 128 memories stored user setups. Room, Studio, and Hall ambience types were built in, a stereo aux input allowed jam tracks or backing music from a phone or mixer, and the two onboard footswitches scrolled through memories while performing. External control came via footswitches, an expression pedal, and TRS MIDI6. Like other cab sim pedals, it offered a stereo output for running into a mixer or audio interface7.
Both pedals sit in Boss's 200 series, a streamlined pedal line43.
