The poor man’s graphic EQ: five bands of seven steps, four presets you edit by pressing the grid.

A graphic EQ you set by pressing the grid. Five bands, seven steps each, one row per band: press a cell and that band jumps to that level — no knob to turn, nothing to confirm. Four presets sit under the left footswitch, and a press writes straight into the one you are on, so editing and storing are a single gesture.
