I played around with the various USA Pre models on the Axe FX III yesterday - my main rig before I got an Axe FX (a II XL at the time) was a Triaxis so I decided to dust it off and dial in my exact presets from back then on the Axe. First, let me say that they sound pretty amazing and feel close to what I remember from the real thing. But I found two inconsistencies between the controls of the various models that don't seem to be mentioned in Yek's amp guide. I figured it might either be due to (very minor) bugs, or because of some differences between the models which are not well documented. Either way, this is what I noticed:
- The "USA Pre Ld1 Red" defaults to an 8 band Output EQ instead of a 5 band Mark. All other models have the 5 band EQ, intended for simulating the "Dynamic Voice" control on the Triaxis. Is this simply a wrong default value or is there a reason why this model has a different EQ type?
- In Authentic mode, all three Ld2 models have "Preamp Presence" and "P.A. Presence" knobs. However, the Ld1 and Clean models only have a "Presence" knob, which seems to be the power amp presence and not the Triaxis "Presence" control as it is a value from 0-10 and not a level control. What does the presence knob do for the Ld1 and Clean models, and what's the reason for the disparity with the Ld2 models?
