Flamma FS22 Delay & Reverb

I haven't had the opportunity to use it in stereo, but when I play it in mono, it feels limited. I mean, there are 8 knobs, a 3-way switch, and 2 modes, but it all adds up to an ambient reverb. It's difficult to get a clean delay, and the reverb is of average amp quality. I think you could get a better sound by using the Fender Champion reverb on onther end Shimer reverb sound cheap? I think using it in stereo or adding another reverb could improve it, but on its own, it's a one-trick pony for ambient, and in that case, it's good.
