Features and functionality
-
The Slammi Plus is praised for its smaller, wah-sized footprint, which is ideal for tight pedalboards compared to the larger Digitech Whammy.

Side-mounted controls require lifting the pedal to adjust settings, which can be cumbersome in low-light environments.
Source -

Build quality
-

It's perfect if you get used to it!
as it doesn't have any mechanical parts, it's movement is not the traditional one like on a digitech whammy or a crybaby wah. It's also difficult to strap it to the pedal board as it's bottom has to move while using it unlike other pedals whose bottom is fixed to the board. Keeping these two issues aside, it's pitch shifting capability is second to none.
