i have the Malekko Spring Chicken reverb pedal... I like it because it replicates a spring reverb on an amp. I don't like reverb pedals that have 3 or 4 knobs for setting parameters... I just wanted a pedal with a single knob like you do on amps, as my current amp has no reverb tank.
Works well for me and sounds great. need more reverb, turn up the knob! I've got a Boss Rv-5 reverb/delay pedal and i just don't like digital reverb.. so tricky to get the right sound.
