That's an alder back, can't guarantee the color will come out the same as most poplar has a greenish tint to it...
I stained that Strat back with two coats of Minwax oil-based "Golden Pecan" finish, then after letting those stain costs completely dry stained the darker Minwax oil-based "Jacobean" stain on top of that; then shot with sanding sealer and nitro gloss lacquer topcoats.
