I was going to say that it might be fun to try as an 
experiment, I bet you'd get great high end if you biased 
right, as an "effect".
One friend that I work with on a casual basis insists on 
recording his vocals on a 4-track cassette recorder with DBX 
engaged, then he plays it back unencoded. he calls it 
"Anti-DBX", and loves the way it pokes through the mix.
