| Pedal | Current draw | Voltage/info |
|---|---|---|
| Modern ”small” pedals (labeled ”Mu-Tron”) | ||
| Baby Phase | 40 mA | |
| Bi-Phase II | 260 mA | 9-12vDC (12vDC ”ideal”, but 9vDC works fine too) |
| Boostron II | 15 mA | |
| Micro-Tron III Micro-Tron IV | 52 mA | |
| Mini Mu | 25 mA | |
| Octave Divider | (modern Mu-Tron 9vDC version) | |
| Octavider Plus | ||
| Phasor III | 115 mA | |
| Ripper | 15 mA | |
| Tremu-Tron | 15 mA | |
| TubeTron | 15 mA | |
Mu-FX series* | ||
| Boostron 3 | ? | 9vDC |
| Octave Divider | <200 mA | 12vAC |
| Phasor 2X | <200 mA | 12vAC |
| Tru-Tron 3X | <200 mA | 12vAC |
Note: Voltage/polarity is 9vDC center negative, unless otherwise specified.
* The ”Mu-FX by Mike Beigel” series were the first ”reboot” of Musitronics, with smaller (but not as small as the current units) size boxes. Those were mostly 12vAC-powered, and can be seen as a halfway house between the vintage/large (and mostly mains-powered) pedals and the current modern/small 9vDC pedals. See the picture to the right for an example of the Mu-FX series pedals.
