does anyone have a really good shcematic for a clipping curcuit for a mic pre. i'd like to have that option so when you overload the mic pre a light comes on and you know to make adjustments.

does anyone have

You may have one in a minute or so, do a search here. There are various (threads about) one LED clip indicators.

the one used in the E/G SSL 4 &6K is OK, let me jnow if you find a simpler one....

There's also an easy one on page 2 of this Rane pdf.  It's in the upper right corner.

It's designed for a bi-color LED.  I'm using several of them in a line mixer and they do the job.  Play with the values of R34, R38, and R41 to alter the response.   Changing the value of R39 alters the LED "flicker."

Are those full-wave detection? (It's hard for me to see, and my acrobat reader won't flip pages sideways without locking up...)

looks like 1/2 wave, signals are summed through a 10k res, then go through 1 diode

Yeah, the SSL one is nice, and DEFINITELY full-wave. That can be important, specially when on solo instrument channels...

In this project on the ESP site there is a simple full wave single led indicator you could look at.  http://sound.westhost.com/project30a.htm

The rane circuit looks full wave to me as it seems to be able to detect both positive and negative peaks, or maybe I miss something ?
(negative peaks go through OL2 and positive peaks go through OL1 I believe...
or the contrary, the Z2A opamp confuses me :p)

Also have a look at the NTP 179-160 compressor - it has a very nice clipper circuit..

The schematic for Dan's Great River  psu board  has an i.c. comparator
to catch both the pos & neg waveforms , works well , starts to glow as it approachs clipping

..sorry, it's the 179-140 - page 13 in the .PDF

http://www.gyraf.dk/schematics/NTP_179-140_Manual.pdf

..the circuit around discrete-opamp A2
