I ended up with the Bright switch on, the Deep switch off, treble set to 1:30, mids at 12:00, bass at about noon... which got pulled back to 9:30 when the PA was brought up to speed. Mid selector switch ended up on 4. Dialling in the tone was a breeze, which previously was not the case with pretty much any other Ampeg setup I've ever used. I was knocked out by how easy it was to make this setup perform. It makes me wonder if the SVT 4 Pro is similar enough to give it a go. It's cheaper and lighter, but I'm guessing sounds very different.
