I use this pedal in my live setup and in my studio, especially with synthesizers.
And in both cases, it has produced astonishing sound.
Slightly larger than average, it is very sturdy.
It sounds as a studio level reverb, lush and warm, with stereo input and output.
Also the Reverb UI is pretty intuitive.
Empress keeps improving the quality of products, updating this often on their forum.
My only regret is that you need to buy another product, the "Empress MIDIBOX", to control it via MIDI.
And, to conclude, I highly recommend this pedal, it's really something special.
