Noah'sArk Distortion M

Not a lot out there on this one, but stumbled across the schematic over on FSB. Apparently it's another Marshall-in-a-box type. Sounds pretty good. Should fit nicely in a 1590B. The 1uF and 2.2uF caps are tantalum in the original but eletrolytics could be used as well. Original 1S1588 clipping diodes could easily be replaced with 1N4148s if need be.

      The 4580 looks like another general purpose part. You should be able to try any dual op amp... 4558, TL072, and similar.

      From what I'm reading, though, it looks like interwebz people think the 4580 is an improvement and sounds "smoother" or "more modern" than most common ICs.

      Anybody else have any experience?

      Use a higher value pot for the gain control. A250k is where I'd start.
