| Pedal | Current draw | Voltage info |
|---|---|---|
| Module 4 | 85 mA | 9vDC recommended. Up to 18vDC allowed, but higher voltages will not change the tone or headroom. |
| The Engine | 83 mA | 9vDC recommended. Up to 18vDC allowed, but higher voltages will only affect side A. |
| Unit67 | 87 mA | 9vDC recommended. Up to 18vDC allowed, but higher voltages will not change the tone or headroom. |
| Vibe Machine v2, v3 | 165 mA | 9-16vDC input voltage – higher voltages will not change the tone or headroom. So 9vDC for this one too, thus 🙂 |
