Yes, absolutely. I'll use jamin.

I was tried LADSPA equalizers (i have TAP, CMT, MCP, REV, SWH, VCO plugins), TAP EQ generally -- its octava measured Q is too wide for this work. I was thought about filters with small Q usage and then "to subtract" result of their work from a basis somehow, but way proposed by Wolfgang is simplest IMHO.
