Generally domestic 2 row pale malt (I like Great Western or Rahr) and crystal malt, usually around 60L. Also, get your sulfate up to around 300 ppm.
My basic pale ale is 2 row, C60 and some wheat. Bitter to 35-40 IBU (Columbus, Centennial, Target, Northern Brewer, Perle) and 1 oz additions at 15 and 5 min (C Hops, Willamette, Sicoe, goldings, etc) 1.050ish OG then 1056/1272/002/S-04 for yeast. Dry hop if you get the itch. Usually this or some variation.
