    hi all,

    i own a Ibanez ATK 400 (Korean), i like the bass much, but i does not sound Musicman like. The sound is to high and has not the MM-Power in it. When the electronic is bypassed (by a wire) the sound is deep and rich. I reviewed the electronic and saw that the Condenser C11 is to small, i replaced it with a 22µF. Now this Bass is a Killer, real deep with lots of highs, and it is kicking like a MM.
    Maybe this is not valid fot the US ATK´s. I read only good things in the forum about them, but the Korean...

    When someone want to fix his Korean ATK, please contact me if you need help.

    best regards

    Cool, I have an ATK 305 and will check if I find the condenser c11 in there.

    How exactly did you bypass the electronics by wire? I would like to try this first before I start with soldering. But, I have to admit that I'm a beginner in electronics and soldering, so please explain it in a language that even I will understand :rollno:

    Thanx a lot!

    the quick and simple (but not the technical correct) version:

    - remove the battery
    - bypass the electronic by connecting the orange and the yellow wire, or output-pin to 5-way-switch if the colours are different to my bass.

    the correct way:

    desolder the orange and yellow wires from the electronic and connects them.
  4. What was the original value for your C11 capacitor ? (the one near the volume pot, right ?)
    Mine says 2A473J.
    I ask this because I bypassed the electronics like you said (connecting the yellow and orange wires) and I couldn't hear any difference in deepness and just a tiny bit off difference in brightness ...

    Hi Guy! I have the same problem. Can you help me? I have ibanez ATk400 , but sound is not as MM. :crying:
  6. I hate to bring up a dead thread, but on the topic of ATK mods on the Pre-amp, can I also change the trimmer pot to lower the output of the preamp even further?
