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 is not designed for acoustics, however, we have tested it on an acoustic before and it gives it more of a sitar-like sound.

Does this 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 right here in the US!

Can you turn it on and off quickly?

Yes. Without taking the device off, you can loosen the side screw, rotate the main body out of the way, then tighten it again.

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.

How did GUITAR-JO start?

Jon wanted a banjo sound for a song he was doing for a musical performance. He didn’t want to buy a banjo and learn it, so he tried to find digital guitar effects, which he soon found fell drastically short.

Jon discovered that dampening guitar strings using a cloth and other soft materials produced a sound similar to a banjo. However, the results were inconsistent, with the cloth often falling out of place while playing. So he started working on making something a little more reliable and came up with a plexiglass dampening device that attached to a guitar body with suction cups. A bar with fabric material on its underside could then be lowered onto the strings, or raised if too much pressure was applied. It produced a sound that was much more consistent with that of a real-world banjo.

When the HECK is this supposed to come out?

Although it may be sooner, we expect to release GUITAR-JO™ to the market late 2017.
