Experience the acoustic guitar in a whole new way


The ToneWoodAmp allows you to play your acoustic guitar with different effects, UNPLUGGED – with the effects emanating organically from the guitar’s sound hole and the body itself.


Similar to the way the strings excite the top of the guitar to produce sound, the ToneWoodAmp excites the back of the guitar, producing sound waves of effects such as reverb, echo, delay, tremolo and more, which interact with the natural sound of the guitar itself.


The ToneWoodAmp is also a multi-effect processor which you can connect with any Amp/PA system and is also an iDevice interface allowing you to experiment with audio and MIDI apps.



For those who don’t have an electro-acoustic guitar, we are offering high quality “technician-free” pickup bundles: a Fishman Neo-D soundhole magnetic pickup for steel string guitars and the Kremona NG-1 tie-bar  piezo pickup for nylon string guitars. Please check the Order page for these bundles.


Amazing Amp-less
Acoustic Experience

The ToneWoodAmp provides the newest and most unique acoustic guitar playing experience without the need for an amplifier! It enhances the natural sound of virtually any acoustic guitar, adds depth, texture and effects, and creates a unique surround sound feel never experienced by acoustic guitar players before (see video testimonials below).

Read more – How it works

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.


Doubles As a
Multi-Effect Processor

The ToneWoodAmp can be used also as a multi-effect processor. In a situation where you need to amplify your guitar, you can connect the output jack to your amp or P.A. system and use the “blend” mode to dial the amount of guitar/effect you want to send out.

Triples as an
iDevice interface

If you desire to experiment with more effects and other cool tools, you can use your ToneWoodAmp with an iDevice and try your favorite apps including guitar effects, MIDI instruments and much more!.
