A no-nonsense reverb

At first, you may think "who would want to buy a one-knob reverb in which almost everything is set for you so that you can only control the dry/wet blend?" and also "who would want to use that ridiculous flerb setting?". Answer to question 2 is "no one" and answer to question 1 is "well, pretty much everyone" because it's on all of your favorite artists' pedalboard. And for good reasons. "Spring" and "hall" are so perfect that you put the blend in between 10 and 1 o'clock depending on your taste and then prettty much forget about it. There are better and more complicated reverbs out there but none that are as simple and dependable as this one.
