What does all this mean?  You’re getting a tough switch that will last a long time in your instrument and look good doing it!

The switch is easy to install. If you have the slightest bit of skill with a soldering iron you can do it yourself. If you do not have that skill, you should have a guitar repair person do it.  The mounting hole is slightly larger than a standard volume or tone pot (12MM vs. 9MM) which means that if you decide to go back to your original setup, you don’t have to buy a new pickguard or repair that hole in your wood.

This package comes with everything:

  • (1) Tesi POCO 12mm Latching Guitar Kill Switch
  • (1) Tesi Quick-Connect wiring Bundle that includes:   (1) 8″ Black/Black ground wire, (1) 8″ Black/White hot wire, (1) 8″ White/Red Power wire with resistor, (1) 8″ 9V Battery Harness with resistor, (1) On/Off Rocker Switch, & (2) Spare 270 Ohm resistors for custom wiring jobs

When used with active pickups and/or a stereo output jack (not included) the Tesi POCO does not require the additional on/off rocker switch.

Each Tesi Guitar Kill Switch is guaranteed against defect for one year from the date of sale.  Contact us for more details.

The Tesi Switch Difference:

Tesi tests every switch before packaging it.  As a result, the failure rate is less than 1%.

If something does go wrong, Tesi switches have a 1-Year Guarantee against defect or failure.

While all of our wiring solutions are built to be installed rather easily, we always recommend that you have a guitar professional at your local guitar shop install it for you.
