    Haha, look what I found. Can I make a analog audio delay with these puppies?

    Also, can anyone ID the components in the 2nd pic?

    2nd image could be high current diodes.
    With those analog delays you can delay any kind of signal.

    Ok thank you, im sure i can find the color codes now that I know what they are,

    The first part was really a joke because I had smaller delay bars that i didint know what they were, and MrChips IDed them for me, and I figured that the delay was to short for a delay effect for audio, but I asked MrChips anyway since I didnt know what kind of time increment music delay was in. These that I posted have much larger values so I asked him half joking.

    Actually It could be that 2nd image is a capacitor.

    24pf cap??

    Musicians, especially rock and heavy metal guitar players are keenly interested in FX boxes that deliver delay effects such as reverb, tremolo and echo.

    http://en.wikipedia.org/wiki/Delay_(audio_effect)

    You can calculate how much delay is required by knowing the speed of sound in air which is 1125 ft/ or 340 m/s.
    That translates to a delay of approx. 1ms/ft or 3ms/m.

    So imagine a room 50 feet long. The sound path to and fro is 100 feet. The sound would take 100ms to return.
    100ms is the delay time you would need to simulate reverb, not 100µs.

    Tremolo and echo would require much longer delay times.

    They are called "feed-thru capacitors".
