Quick and easy way to tune...Remove batter. Tune reso to desired sustain. (Usually about a half to full turn from finger tight) After tension, tune each lug to the same pitch.
Install batter head, finger tighten and then in a cross pattern using your tuning key, turn each lug about a half turn and repeat. After tension, tune each lug to the same pitch and you should have a very doable tuned drum.
