I have both the Ambient and the Slötva (version of Slö with three presets). Both are great, and personally, I think the Ambient is a subset of the latter which has more controls and can work closer to a reverb in the traditional sense. Ambient with the “mix” slider close to its left margin gets closer to regular reverbs but it is not your typical room/plate/spring/hall-type reverb. In other words, don’t expect the Strymon BlueSky or UAFX Golden-type reverbs.I have listened to a bunch of demos for a few hours and I am currently between the Slo and the Fundamental Ambient. Does the Fundamental Ambient do any regular reverb at all? Thoughts on Slo vs. FA in general?
Ambient does not have the Sustain (Hold) function, whereas the Slö does. In more conventional reverbs I also like to have pre-Delay. Neither of these pedals have that. Slö can definitely do a whole lot more than the Ambient can.
I would still go for the Ambient, though, but follow Walrus’ price promotions to get it for below $100.
