Installing Pedal Mods Boss MT-2 Mod Kit

CAUTION: Read all these instructions before beginning, if you pedal is currently under warranty it will not be after these mods. This kit and the instructions do not include any warranty of any kind and you agree to hold harmless the seller of this kit against any and all claims.

Thank you for purchasing the MT-2 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 MT-2 into a serious tone machine.

There is also a new LED to replace the red one, it will not change the tone of the pedal, just change the color of the light. The longer lead goes to the red wire.

Open up the back and take a look inside. There is the main circuit board and a tiny board that only houses the LED. There is no need to remove the jacks or pots for this Kit.

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. In the pic is a detail of the MT-2 board before all the components are removed and which components will be replaced.

Note that there are three components behind the ribbon cable and it’s a good idea to remove the tag board for the pots for easier access to the board.

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.

The diodes,LED, and power supply caps in the next step must be inserted correctly in order to work. The diodes have a band closest to the positive side and the PCB has an arrow pointing toward the positive side. For the LED the longer lead goes to the red wire.

There are two 2n7000 mosfets that replace the clipping diodes that should be inserted with the Gate (G) and Drain (D) together in the hole that the arrow is pointing to. And the Source (S) inserted in the other hole. If you want you can solder the G and D together then clip one of the leads but both leads should fit in the hole.
