  2. Hi!
    I need to find a simple amplifier schematic for my son's
    guitar...Loud enough to be heard well but not loud enough to be able to P.O.
    the landlord.

    Also I need a simple schematic for an echo unit(like a bucket brigade) using
    a 555 chip.

    I have a bunch of spare parts to use on these projects but I'm a novice so I
    need very simple designs...

    Thanks in advance...

    You can't make an analogue delay from 555s ! I don't think you can even get
    those charge coupled delay chips any more anyway. It's cheaper to do it in CD
    quality DSP now.

    ** Hah - it is dead easy.

    Just play the amp in the bathroom.

    On 27 Jan 2006 22:33:48 -0800 in sci.electronics.basics,
    LM386 with input signal full blast on the input and a "rheostat" on
    the output to control volume? Is that whacky or is it just me?

    Probably the design of a recent 'graduate' going by what I hear of the
    skills being taught currently.

    Some of these guitar players want to take advantage of the way the chip
    distorts. The same web site has a variation called "Little Gem" that
    puts a common pot in front of the 386 instead of the rheostat after.
    The manufacturer's data sheet circuit is probably the place to start
    with the LM386.
