Green Ringer 2020 - another approach to simple FWR doubling

[idiot savant]

I noticed a ton of posts lately about the Green Ringer, and FET doubling. Here's something maybe new for y'all.

I've been using this IC for a few years now, and it offers an interesting low parts count approach for a Ringer-style pedal.

In keeping with the original, I've made it as simple as possible, and no simpler. If you want more features, I'll leave that to you!

Enjoy!

Very cool idea.

Tis the green ringer season...

Cool circuit, thanks for sharing...

[idiot savant]

Thanks all!

As PRR pointed out, they're a little spendy, but life's just too short to match jfets...

As a side note, I believe I've seen this IC used before in some interesting compressor side-chains by Rring @ www.circuitsalad.com

So, probably useful for making envelope followers too.

You *can* make the internal circuit equivalent with op-amps, trannies, and resistors...

You would have to match the transistors and get the most accurate resistors, but i think it would be worth it... probably use a quad-op-amp...
Also could replace the input JFET buffer with an op-amp buffer I think...

To the breadboard!

You would have to match the transistors...

Why?

It is a god d"mn great component

Available in SMD only?

You would have to match the transistors...

Why?

probably not really needed (for us DIYers), right?

really cool chip, put one on my order list, i can't wait til they (also some other IC's) come in the mail!
to bad they are smd, it always hurts my fingers somehow.

cheers, Iain
