A year or so ago I bought a cheap used Fish & Chips EQ pedal to try out, messed with it a while, then put it away. I recently got it out to try some mid-range boost and really liked the tone. But it started flaking out on me so I decided to get a better EQ pedal. I was going to get the Boss GE-7 because everyone seems to be using that one, but then saw the Maxon GE601 EQ that had a cool vintage vibe to it. Reading some reviews, some people said it sounded better than the Boss so I decided to give it a try. Wow, this thing sounds noticeably better than the Fish & Chips. I love the sound of the mid-range boost in the 400 and 800 Hz range with the SD-1. I need to solder up some cables to run it through the FX loop on my Ori20, but right now I'm just going old school straight in. I'm very happy with my new EQ pedal day!
