Virtually any Acoustic, or Electro-Acoustic guitar or bass (steel or nylon string) with a flat back or slightly arched back (not an Ovation) is compatible with the ToneWoodAmp and the Magnetic X-Brace. 


A pickup is required! For those who don’t have an electric-acoustic guitar, we offer a high quality “technician-free” pickup bundle: 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.

Full body acoustic arch-top jazz guitar and other f-hole instruments Full body Archtop jazz guitars with f-holes may sound lovely with the ToneWoodAmp (depends also on the natural tone of the guitar) but due to the no-sound-hole limitation it is not possible to install it with the Magnetic X-Brace (we are exploring other harnessing option for f-holes instruments), therefore only temporary solution such as the 3M Blue Painter Tape might hold the ToneWoodAmp to the guitar

Thin body acoustic guitars can work but will be very tricky when it comes to the install of the Magnetic X-Brace due to lack of space. The same is for baritone ukulele and small body guitars such as the Cordoba SM‑CE Mini.

Semi-acoustic electric guitars (Godin Multiac, and Taylor T5 Series) will perform poorly with the ToneWoodAmp

If your guitar has one of the following, the TWA may not be well suited:

  • Guitar with a nonstandard / very small sound hole. i.e.: the Baby Taylor 
  • Guitar with no sound hole
  • Thin body guitar
  • Guitar with an irregular back surface or shape (inside or outside). **Slight arch-back is OK!**

The following is a list of known guitars that are incompatible with the TWA:
  1. Baby Taylor
  2. Most Ovation Guitars
