Fuel Tank Jr + Mooer Tender Octaver = Noise and Power Drain?

    So I posted a few days ago about how unless I plug my Mooer Tender Octaver into its own power supply, it's really noisy.

    I bought a Fuel Tank Jr thinking that the isolated inputs would help, but I've found two problems:

    1) The Tender Octaver on its own is noisy in inputs 1, 2, & 3. But if I put it on inputs 4 or 5, it's fine.

    2) As soon as I plug everything else into the other outputs (still keeping the TO on input 5 by itself), the noise comes back as soon as I switch it on.

    3) The light on the Fuel Tank dims when I plug the Tender Octaover into input 5, whether it's on its own or whether other inputs are in use.

    So I'm at a loss here, if there's an issue with the Tender Octaver or the Fuel Tank. All my other pedals work fine with it.
     
  2. The TO is rated for a current draw of 128mA, the Fuel tank only puts out 120mA per output. Try a different power supply, or swith to an octaver with a lower draw, for instance the TC SubnUp mini only draws 100mA.

    Yeah I'm reading up on MA's to make sure that I wasn't exceeding the current draw. I had no idea the draw on it was so high. I was looking at the MXR Bass Envelope and that's only 14. Do Nano pedals typically draw more current?

    Digital pedals (typically) draw more current.

    Ok, so this is digital? Do you know then if the MXR Octave is analog?

    Yep the MXR is analog. How do you tell? Sometimes they state it in the manual, current draw & tracking can hint at what's under the hood too.

    Thanks guys. I just listed it. I'm going to get something less power hungry.

    Bear in mind that analog octavers are a TOTALLY different ball game. They only do octave down (or octave up fuzz), can only track single notes, and can glitch out on open strings, or low or sustained notes. They sound fatter and involve no processing delay though.
