MultiCab Sim

Got a request for this one, designed by Daniel Schwartz. Seems to be a pretty versatile cabinet simulator. Might be handy to throw this in the same box as the Mini Amp from earlier this week. More info, schematic, etc here on DIYSB.



Also the next episode of the DIYLC tutorial is up on YouTube. Forgot to plug it in the post from Tuesday.

    1. Try adding a pulldown resistor from input to ground (1M).

  7. After the third attempt I still don't know what I do wrong. It doesn't work for me. I checked all components. Could someone help me? Please.

    1. I just finished it. It works. I put at the end of my chain before power amp and it sing nicely.
      From my experience, mostly my circuit doesn't work because few tiny cold solder drop between lines and accidentally connect those lines. Usually after I finished polulating a board, I take a razor and run the tip through gaps between lines and brush it with toothbrush. Work as clean as you can and be patient. If the layout marked 'verified', mostly you will succeed with careful build.

  8. hi everybody!
    is there anything that i should care for, if i would combine this cab sim with the "active guitar di box" from this site?
    i,m trying to build something like a "ultra red box deluxe!" for example: do i need two gain controls? ( maby i can replace one pot with a fixed value.....)
