The ToneWoodAmp can be used on up to five acoustic guitars. You will need to purchase additional X-braces for each guitar that you use.
Once each guitar has an X-brace, you can enter the global settings and select guitar to assign it to bank 1-5.
Each bank will store the Master Gain and Notch Filter settings for the guitar assigned. However, the saved effects will be accessible no matter which guitar you have selected.
