Rub Help: Looking to add a savory taste

Hey, everyone I have been using Jeff's rub I bought on here and really like it.... But I got one of those big jugs of the JB's fat boy rub as a gift and I like it on ribs, But found that if I mix it with Jeff's 3:1 of the JB's I really like the savory it adds. But I am not gonna pay the 13 bucks a jug for the JB's all the time....

So does anyone have any ideas on what I am tasting in the Jb's I could just add to Jeff's rub and save some money?
