Too much reverb in Zynaddsub

Anything that doesn't fit into other topics goes here!
I have notice that all the zynaddsub presets have a lot of reverb which is not good. How do you get rid of it?

I will admit I still have to read this myself. :P

if you need more help still, let me know :)
Most of the presets I've used have no reverb at all as standard, though I often add some. A few of them do have a bit of vibrato and/or detune but that's all I've noticed. Can you give some specific examples of the presets you mean ?
