The latest version of ToneWoodAmp is 2.70 and it includes the following changes:

DI Auto Lock, a new addition to Global Settings that, when enabled, locks the TWA from changing effects or parameters after a set time between 5-30 seconds while using the TWA in DI mode. When locked, TWA can be unlocked by holding the Amplitude button down for one second or by removing the cable from the Output jack..

DI Level Type, another new addition to Global Settings. There are two options, Separate or Master. Selecting Separate, each effect will have its own independent DI volume (prior versions of firmware operate in this fashion). Selecting Master control the DI volume on all effects with one master volume. Each effect will still have an independent gain control.

DI Mute has been changed to a toggle control. Quickly mute or activate DI with a single click of the Parameters button when in DI Mode. Turning the Parameters knob will exit DI Mute.

Chorus Effect is an optional update that replaces Overdrive with controllable Rate, Reverb, and Depth parameters.

Minor changes include: 

  • Increasing the lock and unlock time to one second 

  • Dim option removed from Global Settings (Default to 5 seconds) 

  • Insert Mode now shows current selection (insert>series or insert>parallel) 

  • Notch Low and Hi are now Notch 1 and 2. Notch 2 is full-spectrum (40-2090hz) 

  • Minor bug fixes.
