The processor offers up to 12 simultaneous effects slots, allowing players to create sophisticated signal chains for live and studio applications.
Dual Effects Chain & Flexible Routing
One of the key upgrades of the Ampero II Stomp is its highly customizable dual effects chain.
Multiple serial and parallel routing configurations allow you to split, combine, and rearrange your signal path according to your setup. This makes the unit suitable for complex stereo rigs, dual amplifiers, external effects, wet/dry configurations, and other advanced routing applications.
High-Resolution IR Processing
The dedicated IR loader supports third-party cabinet impulse responses with up to 2048 sampling points for increased tonal resolution.
The unit includes:
- 20 Celestion® speaker IRs
- Powered by Celestion® Digital
- 50 user IR slots
- 1024- and 2048-point IR support
- 24-bit / 44.1 kHz mono WAV compatibility
This provides extensive flexibility for creating realistic direct-to-PA, recording, and headphone tones.
Touchscreen Interface
A 4-inch 800 × 480 color touchscreen provides an intuitive interface for editing patches, adjusting effects, and navigating system settings.
The redesigned user interface makes detailed editing faster while retaining dedicated footswitch and hardware controls for live operation.
USB Audio Interface
Ampero II Stomp doubles as a professional 8-in/8-out USB audio interface, making it suitable for home recording and studio production.
USB functionality includes:
- 8-in/8-out audio
- Wet and dry recording
- Re-amping
- Direct recording into a DAW
- Firmware updates
- IR management
- Patch editing
- Windows/Mac software support
Stereo I/O & FX Loop
The processor features comprehensive connectivity for integrating with amplifiers, pedals, mixers, interfaces, and other studio equipment.
Its stereo input/output configuration allows the Ampero II Stomp to function as a central component of complex pedalboard and stereo rigs.
The stereo FX loop can be used to integrate external pedals into the digital signal chain while maintaining flexible routing options.
60-Second Stereo Looper
The built-in stereo looper provides up to 60 seconds of recording time, with essential functions including:
- Undo/redo
- Half-speed and reverse functions
- Stereo recording
- Footswitch control
It's useful for practice, improvisation, songwriting, and live performance.
Live Performance Control
Three assignable footswitches with halo LEDs provide direct access to patches and effects during performance.
Additional control is available through:
- MIDI IN/OUT
- EXP/CTRL input
- External expression pedals
- Momentary footswitches
- External MIDI controllers
The unit supports 300 presets, organized as 100 banks with three patches per bank.
Acoustic & Instrument Support
Ampero II Stomp includes Ampero-style acoustic simulations and input modes, making it suitable for electric guitar, acoustic guitar, bass, and other instruments.
Input impedance can be configured for:
- Electric guitar: 1 MΩ
- Acoustic guitar: 4.7 MΩ
- Line level: 10 kΩ
