[Elecraft] [K3] ESSB Question

[Joe Word]

Does turning on ESSB have any effect other that allowing wider TX SSB
bandwidth? Say I had a setup using the 2.8 filter and another setup
using the 6.0 filter transmitting at 3.0, is there any difference
other that the .2 greater bandwidth? Does the ESSB feature change the
mic circuit or any thing else? I understand we have two separate EQ
setups (SSB and ESSB).
