Bass strings resonate between 70 to 120Hz, bo dy around 300Hz.
Avoid boosting these to stop feedback. 3kHz and 5kHz give great
"clarity".
Resonances differ— depending on type. Good full sounds around
300 to 500Hz. Clarity at 3kHz.
Extreme lows are at 60 to 90Hz. "Pick" or "pluck" sounds are
around 800 to 1200Hz. Upper harmonics clarified about 3kHz.
Good ful lnes s at 150Hz. Watch for "boominess" around 250Hz.
Mid-range 10kHz.
Bass strings resonate around 100Hz. Wat ch fo r sub-h armonics at
30 to 50Hz.
Good mid-clarity at 3kHz to 5kHz thins out rapidly in high end. Be
careful around 1.5kHz to 2.5kHz to avoid the "bar room sound."
Usually dies under 200Hz. Has great mid-sounds around 1200 to
2000Hz. Top end cuts off at 6kHz.
Rich fullness at 400Hz. Natu ral mids around 1500 to 2500Hz.
Avoid "scratch" s ounds at 8kHz.
Watch for "hot" mids around 2kHz. Low end boost around 400Hz.
Top end clarity at 6kHz.
Great low "kick" at 40Hz. The mids at 2kHz gives the familiar
"punch."
Good fullness at 100Hz. The "crack" is boosted at 2kHz. The
snares extend to above 4kHz.
The main fullness is around 200Hz. The mid punch extends to
4kHz.
Same as to m, but extends down to 80Hz.
Watch for the "gong" sound a round 300Hz. Good "shimmer"
sounds are around 8kHz to 10kHz.
About the same as hi-hat but has more low end around 150Hz.
Depending on the guitar sound driving it and the resonance of each
player's mouth, should have great "bite" a round 1200Hz and dies
above 6kHz.
