The newer MXR/CAE mc402 would be my choice. FSB has some schematics.

The zakk wylde/gtr od combo, virtually the same circuit, vero's on tagboard.  Sounds killer.

Marshall + Les Paul ==> Distortion+

Seriously, simple and classic. Use the 1N270 diodes.

I used 1n270s in mine as well. I did two in series on one side for an asymmetrical setup. CJ and Rej's Plus-Dist board. It's a bit trebly with my all-Fender setup, but if I back off just a hair from max gain I get a really useable crunch. I'm pretty sure if your guitarist asked for an MXR-style drive, he meant the Distortion Plus. It would rip with an LP and Marshall.

Another vote for the D+

Yeah I think the d+ is what I will go with

When I did mine, I threw together an etchable layout that I updated a bit to use a dual op amp so I could move to using a 4558D. I used the open op amp to buffer the Vref. It works well and I think it's a tiny bit of an improvement. I did go with the standard two diode clipping section though. I happen to have an old 70's Distortion+ and the sound is pretty much the same.
