    I have a Voodoo Pedal Power 2 Plus that's years old and otherwise apparently completely normal. It's currently running an OCD in two-port 18V mode, a full-size POG2, and a few other pedals without issue. I'm not using Sag or L6 modeler DIPs; everything's set stock. I've had issues with the AFB. Mind you, my AFB's been on this VPP2+ since I got it in November. I guess I got lucky with the original port selection, but I've had power resets onstage on multiple occasions. This may be related.

    As well as I could can together after a complete tear-down, only one port on the VPP2+ will actually run the Ampli-Firebox. The other ports get either no response or a brief blip on the Enable LED. I've tried both the ports and cables from other working stompboxes, to no avail. I'm aware the VPP2+ has two Line6 ports that feed up to 250mA instead of the usual 100mA. The one port actually does work is NOT one of the Line6 ports; it's a regular 100mA. In A/B mode, the flicker of the Enable LED makes an audible clicking in the signal path. All this goes away if I use the Atomic external wall wart. So,

    Is this really supported on a VPP2+, due to the high current draw? Can you recommend me a more modern power supply with high-mA 9V and native 18V ports and such? Lastly, are you aware if a low-power "blip" startup would erase A/B presets? I appended to another thread that I rebuilt my board this week and my A/B came up with all the knobs zeroed and Boost buttons reset to factory.

    John,
    The Pedal Power 2 Plus should work fine, but you must use outputs 5 or 6 that supply 250mA.
    If those aren't working to properly power the AmpliFirebox then you either have a bad power connection
    cable or something is wrong with the power supply. You should contact Voodoo Lab and find out about testing
    it or sending it in for repair. If the AmpliFirebox wasn't getting the proper amount of voltage and current
    it could act erratically. For now use the factory power supply unit you speak with Voodoo Lab.

    > sending it in for repair

    Yeah, it's like 12 yrs old. Since I've tried multiple cables in multiple ports, I'm about to write off the brick itself. I'm also noticing the prevailing trend toward 18V pedals and 300-450mA power supply ports.

    > it could act erratically

    Related note, is there a reference list of LED error codes? I've seen it illuminate and freeze (unresponsive to buttons), not light up at all, and blip once and go dark again, all in different situations. It feels like those are diagnostic codes linked to specific symptoms. And the other question, could a momentary power blip erase the A/B settings or revert presets to stock like some people have been experiencing?

    John,
    No. There are no error codes to share.
    Over or underpowering the unit can cause random issues.
    Preset settings could have issues, but there is no way for
    the unit to be restored to factory settings because of this.

    I eventually sorted this out. The Voodoo Pedal Power 2+ had to go. I had put the AFB and a POG2 on the two high-current "Line6" outlets at first. However, only one port on the VPP2+ would actually run my AFB without shutting off, and it was NOT one of the two high-current outputs. I also found the flicker of the LED in A/B mode produced an audible clicking in my signal chain. I had used Enable mode exclusively, so this symptom had gone unnoticed. When the POG2 reset power on me during a rehearsal just like the AFB had done, that exposed what the problem was. I got a Truetone CS12 and put the POG2 and the AFB on 500mA outlets. There hasn't been a peep out of either pedal since. That's resolved. I'm surprised it ran as well as it did on a 100mA outlet.

    That VPP2+ is an industry standard, but I'm surprised Voodoo hasn't updated with the times. That supply still costs $169 for nothing but 9V and no more than 250mA. The $179 CS12 had 12 outlets, up to 500mA, sag, 12V, 18V, and 9V AC to run my M9, and every cable that came with it was right-angle. It was an upgrade in literally every feature. It may be worth saying "ensure your power supply can deliver 300mA continuous" prominently in the AFB literature. There are a lot of people in small boards with small power.
