Boss DS-1 Mod Kit( August 2022)

Start by sorting out all the parts in the kit, the parts list above will help!

Open up your pedal and take a look inside. (Your screwdriver might help with this.)

These are the parts that will be replaced

Expose the top side of the circuit board and find the parts that need to be removed.

It’s not a bad idea, especially if you're new to modding, to swap each component out one at a time making sure the pedal still works after replacing each one.

On the next step is a large diagram of the circuit board with highlighted components. The DS-1 has been pretty much the same pedal for over 20 years but there have been some minor changes to the layout. Your DS-1 may have the components in a slightly different place depending on when it was made.

Carefully remove the components using a de-soldering braid.

C1, C2, C3, C5, C8, C9, C10, C11, C12, C13, C14

D4, D5

R13, R14, R16, R35, R39

There is a small circuit board that holds the Red LED. Your kit has a bright orange LED to replace this with.

LED’s are polarized and only work one direction. The longer lead of the LED is the positive side orange wire.

If you decided to do all the mods at once your board will look something like this before you put it back together.

The capacitors and resistors are not polarized. Meaning it does not matter what direction you put them in. The diodes however are polarized and the band on the diode or the long lead on the LED goes on the side that the arrow is pointing to on the board.

You can test the pedal with all of it’s guts out but it may be a little noisier than normal because the metal enclosure is not providing any shielding for the circuit.

Once all the new parts are soldered into place it’s time to put it back together and start rocking !!
