I don't know about you but I have always felt that the sound
on my GS was a bit tinney (too much treble, not enough base).
My friend just purchased a mac plus through USC's book store
($800, can you imagine that? brand new too) and listening to
some of the same sounds that I have on his computer (modem
transfer) proved this to be true. His sounds sounded much more
natural and solid. Using an old stereo trick I have my GS sounding
just as good now.

Go out and purchase a 20 to 30 microfarad capacitor at radio shack
or some where else. These capacitors are used on stereo speakers
to send only the treble or high frequency to the tweeters in your
speakers. Solder or connect this capacitor between the two leads going
to your GS's speaker. This will stop some of the high frequencies from
reaching the speaker and give it more natural balance. In my opinion
this has made quite a difference in the sound quality. With all that
treble missing I had to turn up the volume 1 notch to get the same
apparent loudness.

A higher value on the capacitor will make this affect more towards the
bass end and a lower value will retain more treble. I am using a 30
microfarad.

This is a quick and inexpensive way to get better sound.
