MultiStomp series
MultiStomp MS-50G135 mA
MultiStomp MS-60B140 mA
MultiStomp MS-70CDR125 mA / 145 mA (mono/stereo in)
MultiStomp MS-100BT125 mA / 145 mA (mono/stereo in)**

*Note: 500 mA is the capacity of the AD-16 adapter suggested by Zoom. All the current Zoom multi-effects use the same adapter, and finding out the actual current draw would require measuring each unit at different loads/tasks. At any rate, a supply that can provide 9vDC, 500 mA center negative should work (I don’t know if the plug is the standard 5.5×2.1mm type, though).

**Note: this is an estimate, based on the figures for the MS-70CDR and the stated battery life figures from the spec sheet.
