Thank you for purchasing the GE-7B Equalizer Supreme Mod Kit. After these mods you will not believe it’s even the same Pedal. Included are all the components necessary for total tone transformation, it replaces key components in the signal path to turn your GE-7B in to a high quality low noise eq.
-
Open up the back and take a look inside. There is the main circuit board and a smaller board that houses the sliders, remove the silver screw in the center of the board holding the sliders( see pic) and remove all the tips from the sliders.
-
NOTE: THIS KIT IS FOR BOTH VERSIONS OF THE GE-7B, IF YOU HAVE THE OLD VERSION THERE WILL BE ONE PART LEFT OVER.

After the board is exposed it’s time to start removing components and replacing them with the new ones. Make sure the battery is removed and no cables or AC- adaptors are plugged in. On Page 3 is a detail of the GE-7B board before all the components are removed and which components will be replaced.
-
NEVER heat the solder and try to pull the component out you WILL damage the PCB. Use solder wick to completely remove the solder and the component will come free easily.
-
All of the parts except for the LED, IC, and power supply caps in the next step are non-polarized, meaning you can put them in either direction.
-
If this is your first time modding a pedal you may want to replace the parts one at a time, then test the pedal. You don't need to completely put the pedal back together every time you test it as it will work perfectly fine with all the guts exposed. Some parts will have a more drastic effect than others.
-
If you are quite confident of your abilities you can remove all the components in one step then go through and replace them all.
-
The components to be changed are in the photos. Depending on which board your pedal has.
-
If your pedal uses an ACA 12v unregulated power adaptor remove D5 and R53 then install a jumper as pictured to change it to use a standard 9V center negative supplyThis will also make the LED a bit brighter.
