The BIAS Head delivers responsive, articulate amplification in a compact toaster-sized form factor that weighs just 11.6 pounds. Its intuitive front-panel controls—gain, bass, middle, treble, presence, master, and Modern/Vintage voicing switch—let you dial in everything from pristine cleans to saturated drives without diving into menus. The amp captures legendary tube amp character while offering the flexibility of digital modeling, letting you experiment with speaker simulations and mic placements in real-time to shape recordings on the fly.

The 600W Class-D power amp delivers 850W at 4Ω, 600W at 8Ω, and 300W at 16Ω speaker output, providing headroom for both monitoring and live recording scenarios. Connectivity spans dual L/R line outputs (XLR and TRS jacks), headphone output for zero-latency tracking, mono effect loop, MIDI in/out/thru, USB for Mac/PC, Bluetooth wireless, and two footswitch inputs—giving you multiple routing options for recording direct, blending with cabinet IRs, or running through a speaker cabinet during tracking sessions.
Sound Design & Preset Workflow
Twenty-five onboard custom amplifier presets provide immediate starting points for session work, while nine built-in reverbs add spatial character and context to your recordings. The included BIAS Amp Pro software license unlocks component-level amp design capability from the front panel, letting you modify and create custom presets that capture your exact sonic vision and save them for consistent recall across multiple takes and projects.
