[rhodesp04]

i use a few different ones:

massey tapehead (rarely)

mcdsp ac 1 -> use it for soft limiting

mcdsp ac 2 -> tape sat. on a buss once in a great while, but mainly i use it to tame 808's a lot to clear up some headroom and makes them come out on small speakers better

DuY Valve (has presets for different instruments) -> i use the male vox preset a lot on my vox.
