Quick Start Guide For Matching Lugs
Step 1: Clip the device to the drum hoop. Make sure the microphone end is over the drum
head. Press power.
Step 2: Hit in the center of the drum head to measure the fundamental pitch. Your drum must
be mounted or on a stand to resonate freely in order to measure the fundamental pitch (the
fundamental pitch is the lowest and loudest pitch your drum produces).
Step 3: Hit one inch from any lug. You should get a reading that is 30-100% higher than the
fundamental. If you don’t get a reading that is 30-100% higher, just hit the same lug again or try
hitting a different lug. Once you obtain the proper lug reading, press filter. After filter is set, you
will see the reading displayed in the top left corner. Also, the asterisk symbol will light up. This
will limit displayed readings to +/-18% of the filtered lug reading, thus filtering out higher and
lower overtones.
Step 4: Go around to each lug, hitting one inch away from the lug. Adjust the lugs to an even
pitch. If the lug pitch is lower, tighten the lug. If the lug pitch is too high, loosen the lug.
Note: When you tune the next drum or drum head make sure to turn the filter off and then
repeat the process and reset the filter to the relevant lug pitch. Also, if you change the pitch of
the drumhead substantially (more than 18%), you will also need to reset the filter to the current
lug pitch.
Quick Start Guide For Measuring Fundamental Note
Step 1: Clip the device to the drum hoop. Make sure the microphone end is over the drum
head. Press power, then press note.
Step 2: Hit in the center of the drum head to measure the fundamental pitch. Your drum must
be mounted or on a stand to resonate freely in order to measure the fundamental pitch (the
fundamental pitch is the lowest and loudest pitch your drum produces).
Step 3: After you hit the drum, the nearest note will be displayed on the LCD screen. Also, a
needle will show you weather you are sharp or flat of the note. If the needle points to the left
you are too low. If the needle points to the right you are too high. Adjust to the desired note by
loosening or tightening the lugs. The needle should point straight when you are tuned to a note.
