FAQ and Contact Form

Frequently Asked Questions:

Q: What's the difference between latching and momentary? Which one do I need?

A: Latching switches lock in place when pressed, and will unlock when pressed a second time.  This is useful for anyone who's looking for a 'mute' button for their instrument, or as a pickup or coil on/off.   Momentary switches automatically return to the default position and will only mute your signal while the button is pressed, allowing for the stutter effect.  The most popular type of switch is Momentary.

Q: What does NO and NC mean? 

A: NO and NC are abbreviations for the operation of push button switches.  NO is 'normally open' or 'press-to-make' which means that there is no connection inside the switch until it's pressed.  NC is 'normally closed' or 'press-to-break' which means the connection is always made inside the switch until you press it.

Q: Why are Tesi Switches NO? Isn't that backwards?

A: Adding a new component to your signal path inside the guitar will add resistance (decreasing your signal strength) and increase the potential for outside interference (like hum from florescent or neon lighting).  When wired according to our recommendation, the Tesi Switch does not enter your signal path. Instead it creates a ground loop, sending the hot signal off to the bottomless pit of ground in your guitar, making it silent as death. Typically even other weirdo noises can't even escape it.  NC switches that require you to run your signal path through it can be noisy even when pressed and because they're not typically shielded for guitar use, BZZZZZZ.  You get the picture.  If you have any other questions or concerns about the NO switches we use, please contact us.

Q: What's the fastest kill switch you have?

A: The FASTEST kill switch is going to be the one with the lightest pressure required to get the button to make the connection, which is the DITO Arcade button.  Both sizes are equally light and fast.  Because we use buttons designed for the arcade market, the DITO buttons are made to take a significant amount of abuse, rated at over 10,000,000,00 (ten million) presses before failure. If you can prove that you pressed your button ten million times I'll give you a free one as a reward.  Kind of like getting a 1-up!

Q: I bought a switch with an LED. What's the deal with all these parts? Are they all necessary?

A: In order to make the Tesi Switch experience as simple and painless as possible, we include all necessary wiring for active or passive installation.  That means that there is going to be some pieces that you toss out, or keep for later, or make some crafts with.  There are two additional resistors included in the box in case you want to make your own wiring.  These resistors are 270 ohm which will make the light a little bit brighter and reduce battery life.
Parts required for installation on instruments with active pickups or electronics:     

  • White/Red Battery Wire (this has a 320 Ohm resistor built into the end)
  • Black with Black End (for grounding)            
  • Black with White End (send to hot signal)

Yep, that's it.  Your guitar already has a stereo output jack so you do whatever you want with the other stuff.

Parts Required for installation on instruments with passive electronics:

  • Battery Harness (this has a 320 Ohm resistor built into the end, 9V battery not included)     
  • Black with Black End (for grounding)     
  • Black with White End (send to hot signal).     
  • Rocker Switch to turn LED on/off NOTE:  You can purchase a stereo output jack separately and it will function as the on/off switch when you plug the guitar in.  Stereo output jack is not included.

Q: Do Tesi Switches have a latching option available?

A: Occasionally we do stock latching switches in the FILO, POCO and OTTO switches. Other push button switches may be available by special order.  Please contact us for availability and pricing.

Q: What is the Milliamp draw of your LED kill switches?

A: The LEDs draw very little, about 15mA.  A typical Boss distortion pedal usually draws about 60-80mA.  One decent 9V battery can last up to 35 hours of constant use. 

Q: How quickly will you ship my kill switch?
A: Orders are processed and usually ship within 24 hours (1 business day).  If you order on Saturday or Sunday it may not ship out until Monday.  There are a few exceptions throughout the year. If you need faster shipping, contact us!

Q: Will Tesi Switch perform the installation on my guitar?

A: It's always best to take your guitar to a local tech, but if you're in the Greater Nashville, TN area, Tesi does perform installation and modification services at reasonable prices.  Please inquire at tesiswitch@gmail.com for pricing and lead-time to perform the modification. 

Pickup installation can also be performed.
