I think you’ll find that the guys playing modern heavier stuff don’t use it much. Those that play more variety (classic rock, 80s, funk, modern, reggae, etc) use reverb to suite the style.
If you’re considering adding reverb to your amps as a standard feature, at the least, you should be able to have separate reverb level controls for each module. That seems doable with a spring type.
Ideally, having control of the reverb level and decay for each module/channel would be the best. Of course going that route it’s going to be digital and that would open the door for multiple reverb type selections (spring, plate, room and hall) as well.
I think it’s a great idea, do it!
