    I was about to upgrade from a Cioks DC10 to a Zuma, for both the better noise performance, weight savings and the ability to power my Line 6 HX Effects with a current doubler cable. I've just read on The Gear Page forums that the Zuma doesn't work well with the Ampli-Firebox? I did a quick search and found this post by @Jace Nuzback


    The Zuma is not a good match for the AmpliFirebox. Rather than providing all of the power as soon as it's connected, it ramps up the power. This is an issue for quite a few other pedals too. Strymon is aware of the issue. I'd recommend the True Tone CS series of power supplies instead.
    Jace, is there any way to work around this or get the Zuma and Ampli-Firebox to work seamlessly together? Or is this something that just cannot be overcome? In which case I'd probably cross the Zuma off my list.

    Avoid the Zuma for the AmpliFireBox.
    Again, I think those True Tone CS series are the best thing available right now.

    Thanks, I guess I'll have to look at other options, then.

    The Truetone CS-series stuff doesn't work for me because of the low available current on most of the individual outlets (100 mA), but what about the new Cioks/Eventide switch-mode power supplies? I've left links for you to have a look, in case you're not familiar with them.

    Cioks DC7/Eventide PowerMax (these are more or less the exact same product)
    Cioks 8 (same series as the above, just larger)

    Any of these units will work fine. Choose what you like.
    Please understand that I'm not pushing the True Tone brand either.
    I was actually quite leary of these when they came out as they are a different design
    than traditional power bricks. However our users have reported zero issues with them.
    Also, read this paragraph from their website regarding your issue:

    A major benefit of using a switching power supply is that it can handle far more current (power being pulled out of it) than any transformer-based power supply. Although we had to put power rating labels on each output to satisfy certification agencies (yes, we actually certified these, unlike most companies), the outputs can generally handle far more than the label shows. For example, you can connect a 300mA pedal to a 200mA output, without causing any problems. With a transformer-based power supply, you can’t get away with that. The important thing is to not exceed the total of all the labels. With a CS7, the output labels add up to 1900mA total. That means the total current draw of all your pedals should be less than 1900mA. That total current rating is roughly double the current load of the most common power brick, for a lot less money.

    Truetone power supplies can handle a lot more power on individual outlets than what's stated.
    My CS6 has the AA3 on a 500mA outlet and it works flawless, the AA3 draws quite a bit more than that.
    As long as you don't exceed the total max. current (1600mA for the CS6) you should be fine.

    Contact True Tone with the list of pedals you want to connect, they respond quite fast.

    I have experienced the same thing. I'm powering the AA3 and the Zoom G5n and 3 more analog pedals from the CS6 and didn't even use doublers... Works like a charm

    Okay, I'll decide between the TrueTone stuff and the Cioks 8 or DC7, then. The reason I asked about them is because the Zuma also seems to have no problems powering anything as per the specs and most reviews, and is also a switching power supply but still apparently has issues working well with the Ampli-Firebox, so merely being a switching power supply is no guarantee that it'll play nice with the AFB. So I was wondering if you had any direct experience or feedback about the Cioks 8/DC7/Eventide PowerMax working with no glitches at all.
