Building the Circuit
Before you begin, (as we've said many times), doing any unauthorized modification on your guitar could void your warranty or decrease its resale value.
This circuit should be easy to build as it requires just 5 capacitors and and a six position rotary switch.
We suggest that you start by soldering the 5 capacitors and the one wire to the 6 slots on the rotary switch.
Next, take the free ends of the capacitors you just soldered and twist those around each other.
Now (looking at the diagram), you must cut the "hot" lead from the volume control to the guitar output jack. (these have been labeled A and B).
Now, solder the end of the rotary switch with the attached capacitors to point A then solder the common terminal of the switch to point B.
Plug your guitar into an amplifier and enjoy the new sounds you just created!
