Axe-Fx II Quantum Firmware Release Notes
*******************************************************************************
3.00
Improved Amp block output transformer modeling. New model more accurately simulates dynamic core losses and leakage inductance. The “Xfrmr Grind” knob controls the intensity of the effect. Higher values result in more high frequency response and a more “open” sound. Very high values can yield a raspy, spitty tone common in vintage and/or low wattage amps. Modern “big iron” amps tend to have low values. Note that the audibility is dependent upon how hard the virtual power amp is driven and is more noticeable as the MV is increased. Also note that the effect in real amps is highly dependent on the speaker. Some speaker/transformer combinations exhibit significant high frequency dynamic boost while other combinations yield almost none. As always use your ears as the final determinant.*
Improved triode plate modeling for cases when plate load is complex.
Improved Ruby Rocket models frequency response accuracy vs. Drive knob. Existing presets should be reset by either deselecting and reselecting the amp model or by turning the Low Cut Freq parameter to 10.0.
Extended the range of the Amp block Hi Cut Freq parameter to 400 Hz to 40 kHz. As this changes the preset storage format, existing presets will be automatically updated to use default values.
Added “Dweezil’s B-man” amp model based on a modified Fender Bassman as used by Dweezil Zappa.
Added “Friedman BE/HBE” models based on an original Friedman “Marsha”. These are the original BE/HBE models from firmware prior to 2.03.
Fixed wrong default Tube Bias value in Recto1 and Recto2 amp models.
Fixed importing Cab blocks from Axe-Edit library not working properly.
*Note: The Transformer Grind parameter will be set to a default value and the Dynamic Presence parameter will be reset to 0.0 for any presets created with previous firmware.
