Sounds sent through oscillators?

Hello. I'm a tad interested in making sound effects for music, more
specifically guitar effects and such things. What would happen if I sent
the signals from the guitar through an oscillator? Would it be possible to
send every second "flash" (I'm not very familiar with electronics or the
technical terms) through a different circuit, as long as it ends up in the
same place? What would happen if I sent the signal through a spring?

Thank you.

Springs are used in mechanical reverberation units.

An "oscillator" is a circuit which generates a signal or tone all by
itself - there is no "through," (i.e., other than power, it has
no "input") so I'm not clear on just what it
is you're trying to do here.

The general idea was to use an oscillator in a fashion similar to that of
an effect box. I was hoping that it would be possible to break the sound
up into very small fragments of about 1/1000 sec and send 50% of them
through a different effect circuit, or just disable it entirely, creating
a sound which I am not sure how would sound.

That can be done. Let a 1kHz square wave control the throughput of the
sound, via a transistor or something like that. But it won't sound
nice, atleast not in my ears.

An oscillator is basically a very selective filter built around an amplifier
with carefully controlled gain characteristics. You would probably get the
same net effect if uou had an equalizer with a large number of bands.
Switching fragments of the guitar's output through different bands would, in
effect, serve to totally emasculate the original audio.
That's the way some speech encryption devices work, and if you've ever heard
the unencrypted version of someone speaking through an encryption device,
you would understand... it's totally unintelligible.

If you're after musical effects, then you need to process the audio in a
consistently applied manner. That is, apply a consistent algorithm to the
sound (gain, attack, delay, envelope, etc) in order to make it interesting.
It's not an exercise for the electronic novice without the aid of an
experienced designer.

Any waveform with a lot of discontinuities in it will contain a lot of high
frequency components - how that sounds is anyones guess but it's unlikely to
be interesting.

Thank you.

A fairly simple thing you can do is use a 4066 switch driven by the digital
signal output of an oscillator. The 4066 will open and close the music path
at the rate of the oscillator frequency. I recall several pieces of music
that used this sound, interrupting the music at a rate of several times per
second.

For other types of simple effects I think you would need to build a
multiplier type mixer, and using the oscillator, to create pitch changes to
the music.
