As the title says, really. Will be used for ambient parts on bass, between song soundscapes, etc. There's a few I've looked at: KMA Cirrus Pros: can get really weird, lots of tweakable looking settings, seems like an absolute ambient machine, looks cool. The momentary switching looks fun, but maybe not too usable? Cons: have seen people say it's a noisy pedal, although others disagree. One footswitch on/off isn't ideal. Keeley Caverns Pros: again, sounds great. Looks easy to dial in a good sound. Separate footswitches for reverb and delay is a huge bonus. Cons: seems to be quite a traditional pedal, doesn't seem anywhere near as broad as the Cirrus in different sounds that can be made Also looked at the Source Audio Collider, but honestly it seems a bit big & expensive for me right now. I'd like to stay in the enclosure size/price range as the other two options. Any thoughts/opinions on any of those, or something I haven't considered? Any help much appreciated!
