Heat oven to 350. In the bowl of a stand mixer, cream together the butter, oil and sugar at medium speed. Add eggs one at a time, blending until incorporated, then blend in the lemon, vanilla and almond extracts. Add half the 7Up, blending until combined, then half the flour; repeat with the remaining 7Up, then the remaining flour until evenly blended. Grease a 10-inch Bundt pan with butter; add cake batter. Bake until golden on top and firm to the touch, about 1 hour 15 minutes. Let cool in pan 10 minutes, then invert onto serving platter, and let cool to room temperature before slicing and serving.
