Which stereo effects unit?

I am interested in adding stereo reverb, echo, delay, phasing, flanging, and chorusing to
My sub37. I am currently using an inexpensive unit that sound bad.

I’m looking at these and appreciate your feedback. Thanks.

if you want all that stuff in one unit, you could look at some gtr multi FX pedals?

some older ( and I guess, newer? ) rack mount FX had libraries of FX

Eventide H9 is popular too

“The H9 can run all of the effect algorithms from our TimeFactor (delay), ModFactor (modulation), PitchFactor (pitch shifting), and Space (reverb) pedals as well as some created just for the H9.”
