I purchased a used Boss GE-7 recently and got to put it through its paces yesterday in the FX Loop on my Mesa Dual Rectifier Multi-Watt. To my surprise, the pedal very obviously sucks tone from the amp when the FX Loop is on without the pedal even being engaged. In comparison, I don't experience...
Just looking for a Boss GE-7 EQ pedal thats been modified for a reduced noise floor/improved tone capability (e.g. XTS, Analogman, etc). If you have one and are interested in selling it, feel free to PM me.
