Is it possible to tween ambient reverb if yes how?

I have this tunnel and I successfully made it so the ambient reverb changes to “SewerPipe” for more of an echo however since Ill be entering this tunnel in a vehicle at high speed it’s not going to feel smooth since it instantly changes

Yes, there is a service called ‘TweenService’ you can Tween basically anything with a number or Color3 value.

Im aware but Ambient reverb is an option

You can try using AmbientReverb with it, but I’m not sure.
