Fall in love with your acoustic guitar all over again.

The ToneWoodAmp - allows for acoustic guitar players to add live effects to their instrument without having to connect to an external amplifier!

“Simply switch on the ToneWoodAmp and start exploring the endless possibilities. Your acoustic guitar will suddenly have a new life. There is nothing else on the market that can make your guitar sound like this without the use of an external amplifier or external effect.”  Ofer Webman, creator of the ToneWoodAmp.

Welcome to acoustic guitar 2.0. No external amplifier or effects are needed!

The ToneWoodAmp uses a clever combination of powerful DSP (Digital Signal Processor) and Surface Exciter. Attached to the back of your acoustic guitar, the device vibrates the back of your instrument, producing sound effects such as reverb, echo, delay, tremolo and more, which interact with the natural sound of your guitar. The result is a unique soundscape coming from within the body of the guitar itself, while still maintaining the guitar’s natural beauty, original tone, and untethered portability.

What It Sounds Like?

Jake Allen's video demo above is a great example of how it sounds. We also have many videos on our website and Facebook. Here is another simple home recording we made to simulate the player's experience at home. The recording device was ZOOM H2N. Please note that there are two segments on this demo and that the first sample of each segment is always "dry" ( i'm not the best finger picker so please excuse the performance :-). PLEASE USE HEADPHONES OR GOOD QUALITY SPEAKERS.

The ToneWoodAmp Built In Effects

The ToneWoodAmp feature 3 Reverb types, Delay, Echo and Tremolo. There are another two presets that aren't finished yet.

To switch between effects, turn the “Program Change” knob. Each effect has 3 parameters to work with:

"Store" and "Recall" Capabilities

You can store and recall effect presets to the ToneWood Amp. To store an effect preset, press the Program Change knob for more than 2 seconds until the program number flashes few times. To recall a setting, press and release quickly the program change knob and the setting will be recalled.

What The ToneWoodAmp looks and feels like on the back of your guitar

In terms of weight, there is virtually no impact on your experience. Our prototype weighs close to 11oz, your unit will be around 6-7oz.

Need More Effects? Connect with iDevice and Use Any Guitar Effect App Including MIDI Apps!

In addition to the ToneWoodAmp’s internal DSP, the device can also connect with all iOS devices, so you can use your phone or tablet to produce an unlimited number of effects, and even play Virtual MIDI instruments from within the body of your guitar itself.

How To Attach The ToneWoodAmp

The initial installation and setup of the ToneWoodAmp is fast and easy, It requires no tools, and has no permanent impact on your guitar. Once the magnetic rails are installed, detaching and attaching the ToneWoodAmp to the guitar takes just seconds.

We have two methods of install, both use a base of what we call the “magnetic rails”. The first (original) method include a double sided adhesive strip perfectly safe to all Polyurethane finished guitars (This is the most common finish for modern guitars). The second method (Which we just announced on Dec 7th) is an adhesive free alternative, it includes a set of four magnets easily placed inside your guitar. This option is perfect for high-end or vintage nitro based (Nitrocellulose Lacquer) finished guitars
