Best Twang for Your Buck

GUITAR-JO® is the first and only electric guitar accessory that makes your guitar sound like a banjo.

How it Works

GUITAR-JO mounts onto a flat-body electric guitar. Six individual dampeners are lowered so that they gently touch the strings. That contact gives your guitar a banjo twang, take a listen:

The Main Body goes over the strings and houses the adjusters. The Adjusters are turned to lower and raise the dampeners. The Dampeners are lowered so that they come into contact with the strings. When contact is made, the fabric alters the timbre of the strings to give it a banjo twang. The Microsuction Material has thousands of microscopic air pockets that create partial vacuums between the material and the body of the guitar without leaving sticky residue when removed. The Mounting Base is used to attach the entire unit to the body of the guitar and contains the microsuction material underneath. The Side Screw allows you to adjust the height of the main body over the strings of the guitar. More precise tuning is done with the adjusters for each dampener on the main body.


You’ve got questions. We’ve got answers.

How does it work?

There are 6 dampening pads. Each dampening pad can be adjusted to make a small amount of contact with each string. When the fabric comes into contact with the string, it alters the timbre to give it a twangy banjo sound.

Does it work on acoustic guitars?

It does not sound like a banjo on an acoustic guitar.

Does it attach to curved bodies?

Not at the moment. It’s designed for guitars with a flat body surface. We may come out with an accessory that would be a replacement part for the mounting base which would accommodate more common curved bodied guitars, such as a Les Paul.

Where is it made?

It's made and assembled in the U.S.

Can you turn it on and off quickly?

Without taking the device off, you can loosen the side screw just enough so that the main body can rotate but will stay in place when you take your hand off. Then, just rotate the main body out of the way and back into place with ease.

How does it mount to the guitar?

On the bottom of the mounting base is microsuction material. This material has thousands of microscopic air pockets that create partial vacuums between the tape and the surface. The great thing about it is that it has a strong hold without leaving any kind of sticky residue.

Is the microsuction material reusable?

Yes. If dust collects over time, you can wash it with a damp cloth, let it dry for a while, then it will be good as new again. You can also use scotch tape to pull dirt or dust off.

Does it work on left-handed guitars?
