We claim the ornamental design of a tandem sub, as shown and described.

FIG. 1 is a front perspective view of a tandem sub showing our new design;

FIG. 2 is a rear perspective view of the tandem sub of FIG. 1;

FIG. 3 is a top plan view of the tandem sub of FIG. 1;

FIG. 4 is a bottom plan view of the tandem sub of FIG. 1;

FIG. 5 is a left-side elevated view of the tandem sub of FIG. 1;

FIG. 6 is a right-side elevated view of the tandem sub of FIG. 1;

FIG. 7 is a front elevated view of the tandem sub of FIG. 1;

FIG. 8 is a rear elevated view of the tandem sub of FIG. 1;

FIG. 9 is a front perspective view of a tandem sub of FIG. 1, showing an alternative disclaimed environment;

FIG. 10 is a top plan view of the tandem sub of FIG. 1, showing the alternative disclaimed environment;

FIG. 11 is a bottom plan view of the tandem sub of FIG. 1, showing the alternative disclaimed environment;

FIG. 12 is a left-side elevated view of the tandem sub of FIG. 1, showing the alternative disclaimed environment;

FIG. 13 is a right-side elevated view of the tandem sub of FIG. 1, showing the alternative disclaimed environment;

FIG. 14 is a front elevated view of the tandem sub of FIG. 1, showing the alternative disclaimed environment; and,

FIG. 15 is a rear elevated view of the tandem sub of FIG. 1, showing alternative disclaimed embodiment.

The broken lines consisting of dashes show an environment that forms no part of the claimed design. The broken lines consisting of a double-dot/dash pattern show a boundary of the claimed design.
