Z Besht! I have tried them all and this is the best reverb pedal I have come across till now. I use a small amp setup and the reverb wasn't cutting it so I tried several different pedals until a friend/guitarist let me use his Polara for a recording session and I loved..The Polaras flexible reverbs cover a full spectrum, from the intimate warmth of Room, to the vast expansiveness of Hall, through time with the cosmic power of Reverse, and anchored by Lexicons revered Modulated, Plate and Spring reverbs. In addition to those classics, the Polara introduces the new Halo reverb. The Halo reverb with cascading octaves interspersed in the reverb decays will cast a heavenly glow over your tone. I mean just freaking perfect and diverse reverb to have in your arsenal.
