Title: pedal ideas using Jrc 4558D
Post by: rosscocean on January 19, 2010, 06:07:59 PM
Hello everyone! I've built a couple of simple fuzzes which have gone well and I've got a few jrc4558D's.
Anyone got any ideas for pedals using them? Any suggestions and/or links would be great.
Cheers Ross

Tube Reamer, Tube Screamer, and Orange Squeezer all use a 4558 usually. There are some others, but those three are a good place to start.

Also, you could probably build a simple opamp buffer going into something like the jFet booster. The 4558 is a dual opamp that works well in many applications for guitar pedals. So does the Tl072 I've come to understand, and some others also.

4558 = DOD 308 and Orange Squeezer. Yeah the TS use one, but I HATE TS...

The Ti RC4558 is great. Different from the JRC4558 that most people have.

its an opamp, the vast majority of circuits do use opamps

Virtually ANYTHING that uses op-amps.  The 4558 is NOT a "special function" chip.  It is as mundane a workhorse chip as you can find.  So, for some of us here, asking "What can I build with a 4558?" is a bit like asking "What can I build with 10k resistors?".

Don't worry about "wasting" the chips on anything.  There is nothing critical about them, and nothing you build will be a waste of anything other than maybe your time (if you don't like the resulting pedal).  They're quite plentiful and cheap.  Build away.

If I had to pick one I like the ROG Mockman II.  A great sound from a simple circuit.

cheers man, I'll have a look for the schematic.

the mockman is good, orangesqueezer
