I have the TX equalizer set to suppress the lows and emphasize the highs to get a reasonably-flat RF spectrum with my voice. Also I notch out around 800 Hz since those frequencies are not important for voice communications:
1 50 Hz -16 dB 2 100 Hz -16 dB 3 200 Hz -16 dB 4 400 Hz -10 dB 5 800 Hz -16 dB 6 1600 Hz 0 dB 7 2400 Hz +3 dB 8 3200 Hz -6 dB With those settings my voice looks flat on a spectrum analyzer except for the notch at 800 Hz. I should point out that I'm using a computer-type mic/headset which has flat frequency response. With a communications-type microphone you wouldn't need that extreme treble boost. The settings for non-ESSB SSB are the same except that #8 3200 Hz is +6 dB instead of -6 dB. With those settings the ESSB and SSB spectra look very similar.
