Sounds like a good use for impulse responses to me if you really want
arbitrary amplitudes. Probably the easiest way to construct an arbitrary
one though (without measuring a real system) would be through scripting
(i.e. gnu octave or there's probably a python library for iffts). That way
isn't especially easy though if you aren't familiar with iffts. Once you
have it going there are several LV2 convolution plugins.

Maybe just a graphical eq would do what you want. Thats the closest thing I
can think of to "draw your own amplitude response." Guitarix and LSP (
http://lsp-plug.in/?page=home) have some, including a 32 band from LSP. TBH
I prefer a parametric eq for most tasks.
