Hey man my name is Livi and ill try and explan this in extreme detail.(This is my level of experteace)
Ok man, First you wanna get your drum keys ready. If you can get one drumset key and a marching snare key you are in good shape. But you need to have your snare key. they are cheap as crapp and cost
mabey like 4 bucs at your local music store.
(In case you were wondering) The drumset key is small and compact. The Marching snare key or T handle (Popular for its Handle as a big capital T)Makes your life 10 times easyer by letting you crank those kevlars nice.
Step One: After finger tightning your screws get your drumset key and and turn them at 90 degree angles. Repeat with bottom head. Keep tightning until you hear an annoying *Crack Crack* sound. keep going with your drumset key until tuning gets inbarible. leave it to strech for 45min to 1 hour.(repeat if nesserary)
Step Two: After streching make sure you check and see if the screws are still tight. Here is the hard part, Now grab your marching snare key and turn your key at 90 degrees again IMPORTANT Tune in a star fashion. Start at bottom screw, tune then go directly up, tune go one screw to the left, tune then go back to the bottom screw
dont TUNE AGAIN YET!! now at the bottom screw go one screw to the right so its making a straight line from the last screw you just tuned. and so on and so forth.(This will make your head sound absolutley gorgous.)every once in a while hit the drum so u can hear its sounding better. when the top head sounds decent swich to bottom head and repeat be very slow this can break on you from tuning to hard.
Step 3:Here is the fine tuning. If i were you i would leave it for a while again just to be safe,But you may continue. Repeat the star fasion tuning but tune in smaller degrees like
mabey 50 or so. get a drumstick(Preferbly a marching snare stick) and first hit the middle of the head. contune tuning till the head sounds nice and high and u like the sound.Now take your stick and lightly tap the very edge of the head. If you hear a difrence in sound fix it.(this can take a while lol) when the sides are leveled of well hit the center again and the top head should sound really nice. if not keep fine tuning and be careful you
dont want to rip it.
Step 4: Your top head is tuned congratulations! now repeat with bottom head DO NOT TUNE TO HIGH!! Tune slowly and hit the the drum so you notice the diffrence. When you feel comfortabe with the sound take you thumb and press the center down a bit and hit the sides of the bottom drum and level them out.
Last Part! Step 5: You wanna tighten or lossen the cat intestine(
thats what they were made out of back in the day lol) the material which gives the snare the popular buzz sound. go to the side and loosen all the way so it sound like you turned the snare off. now slowly tun the knob and u will hear a snare sound come slowly. keep hitting your drum while you are turning the knob. when it sounds perfect you have completed the tuning prosses my friend.
Give your drum a hit and it should sound orgazmic lol hope i helped man. Good luck!!
