tube screamer op amp
I've checked out the "Inside Tube Screamer" at R.G.'s GEO site, and thinking about building one.  
Can I use just run-of-the-mill 741 or TLO71 or TLO81 op-amps, or do I have to track down some exotic type? I didn't recognize any of the brands listed in the article.

You need to use a dual opamp - the ones that you listed are all singles.  
The TL072 or TL082 work well... the RC4558 is run-of-the-mill and fairly easy to find. IMHO, the RC4559 works as good or better than the JRC4558 that some people rave about, and it's lower noise.

Book Of The Day The Ultimate Tone, Volume III by Kevin O'Connor
Have you ever wondered if there is a better way to build a Bassman, Champ, Plexi, an 800, AC-30, Bulldog or Portaflex? Or you wanted to build an SVT with off-the-shelf parts? How about a master-volume amp that doesn’t change tone with the master setting? Everything you need to know is right here, including: proper grounding techniques, wiring methods, and mechanical considerations. Eighteen chapters cover the “iconic” amps everyone knows and loves, with schematics and layouts for each, along with the technical history of the product. Eyelet-board and chassis-mounted tube socket construction is used throughout, for easy servicing and modding. TUT3 is very accessible even if you cannot fully read a schematic and is a "must have" if you are going to build an amp for your self.

I suggest putting in a socket and then doing the experimentation. All the duals available have the same pinout.  
I've heard of good results with the RC4558 (raytheon) LM833 (National Semi) TLC2722 (TI) as well as the JRC.
