It works!  Thanks Mark Hammer and Oliver Alex!

Here's another link to Aron's Gallery:

A build pic is on the other first post link.  I didn't have TL074's handy so I subbed one TL064 and oneTL084 - worked fine.  I tried with a couple of  LM324N's (same pinout I think) but they didn't  seem to work.

Anyone know where I can still find this? I can't seem to find it in the gallery through search either 
(I did start on a layout myself, but with two Quad OA's it's a bit challenging for me)

[Mark Hammer]

Thanks!  I'm going to have to try that layout myself.

Just for cross reference Mark,

this is Oliver Alex's schematic you posted back in 2005: (it's still there)

Currently I have this (most of it) on breadboard. works fine and sounds really nice. Can't comment on the noise issues as I did not wire the last opamp after the volume control yet. But I really like how it sounds and decided to make a pcb and box it.

[Mark Hammer]

That's the one.  I was really pleased with it, particularly since there was diddley-squat in the way of trial and error.  I just played my hunches about rolloffs, gain, and such, wired the sucker up, and it worked as well as I imagined.  Sometimes you just get lucky.

Is this single battery version the one thats in Munky's layout gallery? Yahoo is currently not functioning for me to check it out, so I thought I would see if anyone knew.

If not, where can I find the 1 battery layout?

Thanks!

Last time I checked, the layout in Munky's archive was for the 2-battery version.  Oliver's upgrade to the basic design is intended to improve bandwidth and reduce noise a bit, in addition to adapting it to a standard wallwart supply..

Olivers update sounds cool... i'll have to do some digging I guess!

Thanks Mark!
