    Hello all,

    I have a Big Muff Pi currently with 12 other effect pedals. I’m thinking of picking up a Dunlop DC Brick to make my life easier. All pedals use the standard ‘Boss style’ 9v adapter but the Pi uses the 3.5mm. I have two questions:

    1. Does anyone know if the brick comes with the correct adapter for the Big Muff or do I need to purchase one separately? If so, is the 1-spot 3.5mm adapter compatible?

    2. Can the Big Muff be plugged in to the 18v port option on the DC brick? If not I will need to daisy-chain.

    Thank you for any feedback you can give!

    I don’t think it comes with the 3.5mm adapter. The 1-spot one should work.
    Do not put 18v into it. You’ll blow it up.

    Blow it up ‘eh! Well now, that could be amusing at the apex of my solo.

    I’ll order a 1-Spot adapter and see if it helps. I just don’t have any 18v pedals for the three options on the brick – seems like a waste. Thanks for your help EH Man!

    If the Brick was mine I’d open it up and replace the 18v regulators with 9v ones.

    EH Man – another quick thought. Can you please tell me what you think of my current pedal layout? I have just started incorporating EH effects and want to be sure I have them setup appropriately:

    , Boss TU-2, Boss DD-7, Boss NS-2 (Controlling: Boss CE-5, EH Small Stone, EH Pulsar, MD-2, EH Big Muff),

    Thanks!

    Good thought, but according to Dunlop’s FAQ, this can not be done:

    “Can I change my DC Brick to all 9V outputs? No.”

    Sorry, I can’t offer any advice. I play bass and don’t use any pedals.

    Not without actually unsoldering a part and replacing it. They should make it so it’s switchable via a dip switch.

    I agree 100%. Thanks for all your input! All the best.

    So – I received the Dunlop DC-Brick and it does come with a cable that fits into the Big Muff, however, the brick instructions say it is not compatible with positive grounded pedals. I took a risk and plugged it into the muff and the red power light came on. Is there any way I can be sure I have a negative ground Big Muff just to be safe? There is nothing in the Big Muff documentation that came with it.

    All current production Big Muffs are negative ground.
