I'd be tempted to try a Behringer FBQ1502. It's a full graphic equalizer (15 band I think). If it detects feedback at any frequency an LED on that slider flashes which makes it dead easy to cut out trouble on a narrow frequency band. Have used the bigger FBQ3102 a lot (for PA duties) and it's a good bit of kit. Usually cheap as chips on Ebay too.
