Folks- I am looking for an EQ for my Martin D21 acoustic guitar (with Fishman undersaddle pickup) to do a little detail work on the frequencies. The important thing is that it be small: 1/3 rackspace (like my RNC= Really Nice Compressor) would be ideal. Also good (but not as important) would be parametric functions, or at least quasi-parametric (sweepable frequencies, but no bandwidth control). Line level is best, as I'll be dealing with the signal after it hits a mic preamp. So I am not looking for a high-impedance 'stompbox' type of thing. Does anyone have one to recommend?
