Are you talking about H9 or Space?
Reason I ask, for solo colour and thickening, I would tend to think or using a little delay rather than reverb … reverb can get a little lost in the live mix for that use… it can work …but I find it a little harder to dial in properly and it tends to vary widely with different rooms and musicians.
a little bit of delay with modulation to taste helps … if you can run in stereo then a ping pong delay can work well as can a delay with a slight delay of say 7ms
trick is to keep things subtle … make it so it almost not noticeable as a delay until you turn it off … then you notice how much it is actually adding
