Critic Reviews

Don’t Make the Boosting Mistake, Attenuate: MXR M109S Six Band EQ | John Horne

wordpress.com

A versatile but finicky EQ pedal, the MXR M109S offers a wide range of tonal shaping with its 18dB boost and cut across six bands. Its bright LED is stage-friendly, but the sliders can be overly sensitive, making precision challenging. While effective for cleaning up tone and eliminating buzz, it may not suit those unsure about EQ sculpting. Guitarists should use it to attenuate rather than boost excessively, as the changes can be overwhelming. At around $90, it’s an affordable option for those willing to experiment, but not a must-have for everyone.

CHunky

I use it as a controller for my tube screamer to push the midrange of my 6505 and as a scoop for my mesa boogie mark v on top of the eq it already has, by pushing bass into the amp and to add chunk into it.
