1542.0. "inventions" by BRMUDA::DEBARROS () Fri Jul 15 1988 14:32

    	The other day I was in my usual hacking mood.... and I took
    a phono plug from some old headphones and put a 6 ohm resistor on
    it.  I had the mono side  of my SQ-80 plugged in to a amp... and
    I put the phono plug into the other output, and I got some pretty
    neat results.  The effect of the patches had a mix between a stero
    phase effect and a chorus effect.  It was great... then I started
    thinking that If I make different plugs with different resistance
    values????? would the effects get stronger/ weaker.....
    
    any comments?

1542.1Do it...JAWS::COTENeed help? 296-4596Fri Jul 15 1988 15:1411
    The MONO output probably sums the 2 stereo outs if there is nothing
    in the second jack. By inserting the plug you may have fooled the
    machine into sending two descrete signals out each of the jacks.
    Since you only had a single audio out running you weren't hearing
    the full stereo sound.
    
    I'm not sure the resistor (or one of *any* value) had any bearing
    on the sound, but if you got a musically usefull effect an nothing
    caused smoke, go for it...

1542.2wow.. Technicolor !SALSA::MOELLERFri Jul 15 1988 16:016
    I agree with Edd.. putting a resistor in one side of a stereo circuit
    should do nothing cool in terms of phase cancellation, flanging
    or anything.  No, what I think you heard was stereo !  I like it
    too !

 	Thanks... for the feedback.  

	When playing sequences.... using sayyyyy 6 different sounds, only
certain patches are played with the chorus/stereo effect, and others are
played very dry but with a long sustained reverb effect.  

Havent seen any smoke yet.!

    Actually, I sorta happened on something mysterious like that that has
    never been explained to me.
    
    As a kid, I had a real cheap 12 watt guitar amp.  I had to use a
    distortion box to get any distortion or gain out of it, and even
    way back then I HATED distortion boxes.  In those days, they called
    them "fuzz boxes", a term which seems to have died somewhat.
    I called them "buzz boxes" that's what they sounded like to me.
    
    Anyway, I also had this ANCIENT "Revere" reel-to-reel tape deck
    with a builtin amp and speaker.  It had a PA mode.  I made the
    experiment of plugging my guitar into it without much success.
    It wasn't loud enough, and the tone wasn't very interesting.
    
    Then one day, I tried it again.  It was loud and gave me a really
    great sound.  Not a "buzz" or a "fuzz", but what we now call
    "Overdrive".
    
    I managed to figure out that the reason it sounded different that day
    was because I didn't plug the plug ALL the way into the tape deck.
    It was sorta half out.  Doing that is what caused it to sound that way
    and I used it for years as my guitar amp.
    
    At the risk of "waxing superlative", it really had a great sound that
    I wish I had today (it has since died and parts are unavailable).
    
    My question is, why did pulling the plug somewhat out cause the
    gain to go up like that?

    I have one of those tape decks (still works). The phone jack input
    is a sterio one, where there are multiple gains, depending on the
    length of the 1/4 phone plug (strange stuff). These were made for
    use in schools & were practically indestructable. I'll vouch for
    the tone - an overdriven tube amp, into a saturated transformer
    core just has a certain sound that works well for a guitar sound.
    I used to do the same thing back in the late 1960's with my 3M
    (Revere) tape deck.
