From the post
If the Palisades is too much for you, the Dunes has a much smaller footprint and less controls to get distracted with. Pretty standard Tube Screamer clone with clipping options and a couple tone shaping switches. Might be a bit of a squeeze but it will fit in a 1590B with board mounted pots.
