Several boutique pedal manufacturers (e.g., Effectrode , Kingsley , Victory V4 ) use Amplitube-like modules to run tubes at genuine high voltage inside a standard pedal enclosure. This yields dynamic response and harmonic complexity unattainable with "starved plate" designs (which run tubes at 9V–30V and sound muddy or lifeless).
There are several types of amplitude, including: amplitubes
| Feature | Traditional Tube Amp | Amplitube Module | |--------|---------------------|------------------| | Size | Large (rack or head/cab) | Tiny (fits in palm) | | Power input | 120V/230V AC mains | 9V–24V DC (safe) | | Warm-up time | 30–60 seconds | ~5 seconds | | Microphonics | Common | Greatly reduced | | User serviceability | Easy (socketed tubes) | Difficult (sealed) | Several boutique pedal manufacturers (e
