The Petal is cool, but way too big format for my pedal board. I'm aiming to cram mine into the 1590B enclosure size, single foot switch, 4 knobs. Stereo in / out (1/4 TRS), Midi in/out (1/8 TRS), 2 Leds. Ideally then I can have a few of these on my board in different positions for relatively cheap.
