We recommend good quality Alkaline batteries like Energizer or Duracell.
With firmware version 2.56 or later, it is possible to use Ni-MH or Ni-ZN rechargeable batteries.
Most batteries designed for high-drain devices will work well.
Carbon Zinc batteries do not hold up well when used with the ToneWoodAmp because they cannot carry a large loads.
Your TWA settings will also affect the battery life.
If the gain is set too high and the louder sounds are causing the Tonewood to "clip", it will consume excessive power.
Also, if the Tonewood is installed with the transducer directly above an internal brace in the guitar, it will have to work harder to make sound.
Make sure that you experiment with the placement to find the most balanced sound before permenantly attaching the X-brace.
We recommend using rechargeable batteries with your ToneWoodAmp to cut down on your cost of use, as well as pollution and waste.
Our favorite is the 2550mAh Panasonic Eneloop Pro.
Duracell Rechargeable also work well.
There are some things you will want to consider when selecting your batteries.
A 3000 mAh battery will long outlast a 600 mAh battery. so please take this into consideration when ordering. We recommend at least 2300 mAh
Be sure to set your TWA battery type to your selected battery to ensure the accuracy of your low battery notification.
To change your battery type:
- Combo-click the Effects and Parameters knobs to enter the settings menu,
- Turn the Effects knob until you see the word battery and then click the Effects knob to select the battery options.
- Turn the Effects knob to the desired battery type (Alkaline, NiMh, or NiZn)
- Click the Effects knob to select this type.
Warning: If you are storing the Tonewood for extended periods of time, remove the batteries.
Batteries can leak and destroy the circuit board in the Tonewood.
Also remember, there are 3 batteries in the Tonewood. Sometimes the battery that is far inside may get stuck.
Be sure to change all 3 batteries at the same time.
If one battery is low and the others are new, the low battery may leak.
