Fractal Audio has announced the availability of a new firmware targeted at its Axe-Fx II XL, Axe-Fx II Mark I, and Axe-Fx II Mark II digital guitar preamplifiers, namely version 15.00, which contains a lengthy changelog and requires additional files to be installed.

Specifically speaking, version 15.00 adds Variable-Q EQ types to Graphic EQ, allows 4 Scratchpad IR locations, removes the Amp block Thunk parameter, and changes the name of Mstr, Level, and Damping options in Amp block to Master Volume, Output Level, and Negative Feedback (it improves accuracy).

In addition to that, the accuracy of Amp block’s feedback network, power supply, and Hi Cut control features is raised, the triode modeling, cathode bias modeling, and virtual power amp algorithm are improved, and several other features and options are added.

When it comes to fixes, this fresh release resolves the source impedance problem with Solo 100 amp models, the drive level issue encountered when Plexi 50W and 100W amps are used, and corrects several mistakes regarding the Dr Z MZ-38 device.

Moreover, the Bright Cap and coupling cap wrong values, the Low Cut improper frequency, and numerous other errors and issues will be resolved if the compatible preamplifiers are upgraded to version 15.00 (the complete changelog is displayed on the description page of each download).

To do so, the producer highlights that you must first install the Fractal Audio Axe-Fx II USB Driver then the Fractal-Bot Utility, and only afterwards get the appropriate archive for your preamp model. Also, know that the additional files are available for both Windows and Mac OSes.

If installed, simply extract the newly downloaded archive, run the Fractal-Bot application, and follow the instructions for a complete and successful upgrade.
