The following frequencies are pretty close to the actual guitar frequencies. Use this framework to
estimate frequencies that are ringing or feeding back.

Low E

80Hz

(G on low E = 100Hz)

Low A

110Hz

(C on low A = 125Hz)

E on D string 2nd fret

160Hz

.

A on G string 2nd fret

220Hz

(G on open 3rd stg = 200Hz)

C on B string 1st fret

250Hz

.

E on 1st string

320Hz

(A on 17th fret 1st stg = 880Hz)

A on 1st string 5th fret

440Hz

(B on 7th fret harmonic= 1KHz)

E on 1st string 12th fret

640Hz

(E on 5th fret harmonic = 1.25KHz)

Well kids, before we close this installment of Soundcheck, here are a few extra sound tips to keep you busy until next time.

  • As a general tip is a good idea to always check your monitors last. This way you ensure the best possible sound without feedback in the house speakers If you have a smooth house mix, you won't need a lot of monitor level. This philosophy is great at minimizing the feedback problems hot monitor levels can create. It can also save your hearing.
  • To clean up the vocals, drop the low mids between (125 to 300 Hz) 3 to 6 dB, boost 6 kHz by 3 dB, and use the 100Hz shelf control to cut lows by 3 to 6 dB.
  • To clean up bass guitar, cut the lows a bit, lower the bass amp volume onstage or reduce the amount of LF from the bass amp. Compress the bass signal if necessary. A threshold of 10-15dB with a slope of 4:1 is “ooh so nice” at fattening things up.
  • To fix a flabby kick drum, roll off the low end (125 to 150 Hz) and boost at 2 to 3 kHz.
  • To fix a tinny guitar sound, aim the amp across the stage rather than into theaudience.

    See ya next time !
