vibrato unit replacement

[benfox]

Hi
I'm planning to do this
http://sound.westhost.com/project49.htm
Or maybe something else witch vibrates good !!! If you have stuff....
But this one seems to be quite easy to me and i don't want something too difficult.
I wanted to know if in the schematic from the link upside i can use a 4558 instead of a 1458

Also i wan ted to know if it exists a schematic of vibrato including those parts mn3102 or mn 3204
That's all
I hope you understand my post
remember i'm benfox the french guy

Looks like most any opamps will work. Use sockets when you build it that way you can try different ones.
Also socket the Fets they can be a bugger to match sometimes and if there not matched you may get little or no effect.

Maybe not for the LFO - though the inputs aren't being pulled too close to the rails so a number of amps should work - but for the audio part, sure.
