X/M32:
I like the Hall Reverb, The Chamber Reverb, and Ambience. Turn the Diffusion all the way up, and the modulation all the way down. Low cut at 500 or higher, and take the sizzle out of the top. For drums, set Predelay to minimum.
I hate the Vintage Room and Vintage Reverb - it's impossible to get rid of the flutter. I’m not a fan of the Plate either – sounds like an empty fuel tank.
The best source for reverb testing is a hi-hat. If a reverb sounds good with a hi-hat, it will sound good with anything. Very few sound good with a hi-hat - it drives 'em nuts.
