I just bit the bullet & pulled the trigger on the Darkglass X. I want the smallest possible package. I sure we bass players could pop into a store to check things out. I've been using the same OD for over 20 years & never really liked it. I don't use it much, so it wasn't really a priority tp make a switch. Suddenly, I'm on a mission I ordered the Tech 21 DUG pedal as well. I don't think I'll use it live but I'm curious about it. And I love DUG! The Darkglass X series looks to have put some thought into their designs. We'll see what happens!!
