[sdiy] Preamp circuits

[David G. Dixon]

I'm looking to build a simple preamp circuit so I can run a microphone
through my ring modulator and scare the neighborhood kids on Halloween with
my rendition of "The Humans are Dead".

I was simply going to chain both sides of a TL072 with, maybe, 10x gain on
both (exact number to be determined to achieve roughly 10Vpp output), with
perhaps a 474 monolithic AC coupling cap on the input and an attenuator on
the output.  The whole circuit would be about 1 square inch.

Am I missing something here, or is it just about that easy?

While we're at it, does anybody here have a preferred circuit for an
envelope follower?  Offline responses are OK.
