Benefits of having multiple Op amps?
« on: January 28, 2018, 11:41:02 AM »
I took apart an old computer speaker and found a jrc4558D inside, I wanted to build a simple distortion pedal and thought itd be cool to use it.
So far Ive only built a simple one op amp guitar amp using an lm386, and I really liked it actually, so im still almost a complete beginner.
Ive found out that the 4558 I have is a dual op amp, so id like to use both somehow if im gonna use it. What are some cool things I can do with two op amps that I cant with one? My original idea was just one op amp for gain and some hard clipping after it. What could I do with the second op amp?

Most pedals based on the Tubescreamer are using 2 opamps. Go find one that appeals to you

With some googling you can find several layouts and breadboard wiring diagrams.  The Tubescreamer is a good project for a 4558.
