I was wondering, what are the advantages of the Digitech S200 compared to the S100?
The S200 has a few more features than the S100. The S200 has a larger display, a De-Esser effect and slightly different presets. The S200 also has more control available through MIDI commands beyond program changes. The footswitch can be configured on the S200 as to what it will control whereas the S100’s footswitch control is limited to program up, down and bypass.
