Explore Tone Project

AI-powered multi-
dimensional sound engine.

Guitar tones with unprecedented realism, responsiveness, and inspiration—transforming your playing through tone that finally feels right.

Experience tone that feels alive.

BIAS X delivers guitar tone with realism, responsiveness, and inspiration. It feels like you're playing through a dialed-in tube amp in a pro studio—because our AI-powered engine doesn't just simulate tone, it reacts to your playing like the real thing.

Amplifiers

ADVANCED AI-POWERED MODELING

BIAS X uses advanced multi-point Agentic DSP to replicate the touch sensitivity and dynamic behavior of real tube amplifiers. With 33 models, each amp responds to your playing—cleaning up when you play softly and saturating with harmonics when you dig in.

You’ll feel it.

From shimmering cleans to high-gain punch: notes bloom naturally, chords sound full, and dynamics translate perfectly. You’re not fighting your gear—you’re flowing with it.

Adaptive Circuit Modeling

Feels alive under your fingers—responding to pick attack, playing dynamics, and volume changes like a real tube amp, giving you the expressive range to convey every emotion.

Bias-Point Shifting

Creates that sweet spot where notes bloom and sustain naturally. Experience the warmth, sag, and harmonic richness that makes vintage amps so inspiring to play.

Dynamic EQ Response

EQ controls that respond musically like real amps—less clinical, more inspirational. Cut through a mix perfectly with tone controls that interact naturally with your playing.

Harmonic Fingerprinting

Each amp model has a unique harmonic signature derived from its physical counterpart, preserving the subtle tonal qualities that define classic tone.

Transient Accuracy

Captures the micro-details of attack and decay that define an amp's feel, from the immediate response of a Blackface clean to the compressed attack of a high-gain British head.

Power Amp Saturation

Accurately simulates how power tubes compress and distort when pushed, creating the rich, three-dimensional saturation that's missing from simpler modeling approaches.

Experience the dynamic response and harmonic complexity that make our models feel like real tube amplifiers.

Effects

AI-ENHANCED PRECISION

Our 63 effects utilize component-level circuit modeling to deliver the organic, responsive behavior that makes vintage analog gear special. Advanced circuit analysis accurately models how components interact, creating effects that respond dynamically to your playing.

You'll hear it.

Each effect undergoes a rigorous 20-step calibration process overseen by professional producers. You'll hear and feel the difference immediately—tape echoes that saturate naturally with authentic frequency degradation, compressors that model the behavior of optical, FET, and VCA circuits, and overdrives with the precise harmonic complexity of rare boutique pedals.

Dynamic Distortion

Overdrive pedals that clean up when you roll back your volume and saturate beautifully when pushed.

Modeled Component Interaction

Get the magic of vintage pedals where components interact to create sounds that range from subtle warmth to creative chaos.

Adaptive EQ Curves

Tone controls that feel musical and intuitive—turning knobs results in useful sounds throughout their range, not just at specific sweet spots.

Analog Noise Modeling

Subtle, musical noise characteristics are preserved where appropriate, while unwanted noise can be easily eliminated.

Temporal Response

Time-based effects like delays and reverbs capture the character of analog and vintage digital units—from clear transients to smooth, natural decay.

Input/Output Saturation

Effects simulate the subtle compression and harmonic enhancement that occurs at input and output stages of classic gear.

Cabinets

3D CABINET MODELING

Our cabinet models deliver the three-dimensional sound of professionally mic'd speaker cabinets. Going far beyond traditional static IRs, BIAS X employs advanced DSP to model the dynamic physical behavior of real speakers—from cone excursion to power compression.

Cabinet Masters

We partnered with an industry leader in studio-grade impulse responses - Spectre Digital - to bring some of the best, most sought-after cabinets to BIAS X. Unlock brand new meticulously captured cabs to shape your tone.

Immersive Sound

Hear your guitar in three dimensions—with depth, space, and presence that flat IRs can't deliver. 

Dynamic Cone Behavior

Feel how bass notes tighten up when you dig in and high notes shimmer with harmonics. Get that natural compression that makes recorded guitars sit perfectly in a mix.

Microphone Modeling

Access the sound of expensive vintage microphones perfectly placed by a seasoned engineer for studio-quality tone. 

Intermodulation Effects

Experience the massive wall-of-sound effect that comes from multiple speakers working together. Get the complexity and harmonic richness that makes 4x12 cabinets legendary.

Volume-Dependent Resonance

Feel how cabinets behave differently at various volumes—from tight and focused at lower levels to harmonically rich and resonant when pushed hard.

Spectre Digital Cabinets

Industry-leading IRs that add depth, character, and speaker realism to your tone—captured by the experts at Spectre Digital.

Signal Chain
& Control

EFFORTLESS CONTROL, INFINITE FLEXIBILITY

BIAS X delivers pro-level tone design through a clean, intuitive interface—built for speed, freedom, and precision. Whether you’re sculpting subtle textures or unleashing layered sonic chaos, the redesigned workflow keeps your creativity front and center.

Dual Signal Chains

Split your signal and process it in two parallel paths—each with its own effects. Stack or pan them for wide, layered, or contrasting tones.

Drag-and-Drop Workflow

Rearrange amps, cabs, and effects visually and instantly—build your chain in seconds.

Streamlined Preset Manager

Organize, and recall tones fast with an overhauled interface built for clarity.

Flexible Routing Matrix

Experiment with parallel paths, stereo splits, and creative FX placement. Turn on the global Doubler effect to double your signal for added width.

Smooth Real-Time Control

BIAS X offers an intuitive, easy-to-use signal path interface. Move components horizontally or toggle them vertically to adjust gear placement on the fly.

Revamped Gear Browser

Browse, compare, and swap gear with a faster, more intuitive experience.
