3.00 Release Notes:
NOTE: THIS VERSION WILL LIKELY CHANGE THE SOUND OF EXISTING PRESETS. THERE HAVE BEEN NUMEROUS CHANGES AND IMPROVEMENTS. YOU SHOULD AUDITION ALL YOUR PRESETS AFTER INSTALLATION AND CHECK FOR PROPER OPERATION AND TONE. AN AMP MODEL CAN BE RESET BY TEMPORARILY CHANGING THE AMP TYPE AND THEN CHANGING BACK TO THE DESIRED TYPE. THIS WILL LOAD THE MODEL WITH DEFAULT PARAMETERS.

NOTE: FACTORY BANK A HAS BEEN REDONE TO REFLECT THE CHANGES AND IMPROVEMENTS. THE SYSEX FILE TO INSTALL THIS BANK IS INCLUDED ALONG WITH THIS FIRMWARE.

  • Added IR Capture feature. Please see the separate instructions for details on the use of this feature.
  • Greatly improved power amp modeling. New pentode model with adjustable hardness. Improved power supply modeling. Improved screen grid modeling and bias excursion modeling (more apparent “knock” on high-gain tones).
  • Added POWER TUBE HARDNESS parameter. This parameter adjusts how rapidly the power tubes enter saturation. Higher values give a slightly more aggressive distortion character. Lower values give a smoother breakup.
  • Added TRANSFORMER MATCH parameter. This is an extremely powerful parameter that sets the relative output transformer primary impedance which in turn controls how easily the power tubes are driven into clipping. The higher the Master Volume setting the more pronounced the effect of this parameter. Decreasing the matching causes the power tubes to clip later and therefore the phase inverter and grid clipping becomes more predominant. Increasing the matching causes the power tubes to clip sooner. At lower settings the speaker resonance will be more pronounced, at higher settings the speaker resonance will be less pronounced. For optimum results bring up the Master until the desired amount of power amp distortion is achieved, then adjust the matching until the character of the distortion is as desired. The various LF and HF resonance parameters interact strongly with this parameter so be sure to experiment with those as well when crafting your ideal tone. The value of this parameter is relative to the actual transformer matching which is set internally and not directly exposed. The value is reset to 1.0 whenever they amp type is selected.
  • Added AMP VOICING parameter. This parameter voices the amp to a variety of tonal styles. Voicings take the guesswork out of mix engineering by automatically crafting the tone like a professional engineer would. Choose “Neutral” for the raw amp sound. Choose one of the other voicings to rapidly achieve a mix-ready tone.
  • Improved speaker load modeling. Now incorporates magnetic eddy current losses.
  • Added speaker impedance graph to the Amp block and moved all related parameters to that page. This graph allows you to visualize the resulting speaker impedance curve and how the various parameters affect the impedance. Note that the power amp frequency response will not equal the speaker impedance if the Damping is greater than 0. This is because negative feedback flattens the response curve.
  • Added quick reset to amp block graphic EQ. Pressing Enter while in the EQ menu resets all bands to zero.
  • Added mid-frequency resonance to Amp block. While most speakers don’t have a mid-frequency resonance, this parameter allows you to fine-tune the edge-of- breakup profile enabling you to achieve “hyper-realistic” tones.
  • Added “TX STAR” amp model. This model is based on the lead channel of a Mesa Lonestar.
  • Added “FAS WRECK” model. This model is based on the original WRECKER 1 model from the Axe-Fx Ultra.
  • Added “PRINCE TONE” model. Based on a single-ended Fender Princeton model 5F2- A.
  • Reworked “MR Z 38 SR” model. If you are using this model it is highly recommended that you reset the model by selecting another model and then reselecting the “MR Z 38 SR” model.
  • Reworked “BRIT JM45” model. Model is now based on Channel 1 (the bright channel).
  • All amp models have been reworked to some extent. The models listed above received major rework.
  • Reprocessed most Redwirez cabinet IRs to reduce excessive low end.
  • Reworked all mic models and added Proximity parameter to allow the user to adjust the desired proximity effect.
  • Improved Spring Reverb modeling.
  • Added Drive parameter to Spring Reverb modes. Added LOWCUT parameter to Pitch block.
  • Added 6 dB/octave slope to Delay block EQ.
  • Changed preset recall “wraparound” so that recall stops at the wrap point briefly. Continuing to increase or decrease the value will then result in the preset wrapping around after a brief period.
  • Improved Output Level knob tapers.
