Hello i've been looking around for some auto swell effects. I've heard that some of those effects don't work really well with polyphonic arrangements. Some of them have a hard time working with chords for exemple. I've been really interested in two pedals but there's almost no review or demos on bass. Malekko Sneak Attack this one is also a tremolo, but i don't know if it works in poly mode EHX Attack Decay this one seems to have a poly mode Im open to other suggestions, but the poly mode is not negociable. Thanks.
