but also with regards to punch and overall dynamics.
Most notably that the model would sound more "direct", like the sound was coming off the face of the speakers whereas the real amp would sound like it was coming from around the speakers. V13 made a big difference in that and now with the new triode modeling I don't hear that difference anymore.
Parameters are never changed during a firmware upgrade, except when noted in the release notes.
I've just compared five of my reference amps with their models. Deluxe Reverb, Carr Rambler, Bandmaster, Princeton and Twin Reverb. The models are more accurate than ever. The only one that was off was the Bandmaster because the model assumes V1 has been removed and I had put V1 back in. Once I reduced the Master Volume to simulate putting V1 in the model was spot-on.
The breakup, pick response and response to rolling off the volume knob are so close that I cannot tell which is which when I do my blind A/B test.
Whether or not V14 is exactly the same as V13 I don't care. All I know is the models are uncannily accurate and sound great. When switching to the old modeling (which I can do in debug firmware) the pick response is not as accurate. It lacks power and punch and feels "congested" when picking lightly. It IS cleaner when picking lightly with the old modeling algorithm but it doesn't respond the same as the amps. The amps break up more when picking lightly. With the new modeling the breakup is the same when picking lightly.
FWIW my Deluxe Reverb is nearly impossible to get clean. With the volume on 2 it will still break up with my PRS (as will the model). Note that Fender amps are indicated from 1-10 whereas the Axe-Fx indicates from 0-10 so '2' on a Fender is approximately 1.1 on the Axe-Fx.
The new triode modeling is audibly more accurate when you compare it to the old algorithm. Especially at edge-of-breakup but also with regards to punch and overall dynamics. I did lots of testing and critical listening comparing just the preamp modeling with actual tube preamps. The new algorithm is so much better that I felt it was unwarranted to include a Global option to select the old algorithm. I could explain what is going on but I would be giving away some trade secrets.
I just tested the Deluxe Reverb again. I did my "double-blind" test where I randomize the A/B selection and then press the A/B switch to select between the amp and model and try to guess which is which. I failed and guessed that the model was the actual amp. I used to be able to pick things out that would give it away. Most notably that the model would sound more "direct", like the sound was coming off the face of the speakers whereas the real amp would sound like it was coming from around the speakers. V13 made a big difference in that and now with the new triode modeling I don't hear that difference anymore.
I just face-palmed myself for not realising this. Makes a big difference to the gain & also affects the tone controls. "3" on the dial is when a lot of Fenders can start to break up when hit a little harder, especially with HBs, which is a lot lower on the Axe:Note that Fender amps are indicated from 1-10 whereas the Axe-Fx indicates from 0-10 so '2' on a Fender is approximately 1.1 on the Axe-Fx.
Yes. It's a straight-line fit so use y = mx + b.
At 1 on a Fender it's 0 on the Axe-Fx therefore we can write 0 = m + b. At 10 on a Fender it's 10 on the Axe-Fx so we can write 10 = 10*m + b. Solving these two equations yields
m = -b
10 = 10*m - m
10 = 9*m
m = 10/9 = 1.11
b = -10/9 = -1.11
So, given the Fender knob value as 'x', the Axe-Fx equivalent value would be
y = 1.11 * x - 1.11.
You skipped 7 in you chart and things are off after '5'. Here is the corrected data:
Fender____Axe
__1______0.00
__2______1.11
__3______2.22
__4______3.33
__5______4.44
__6______5.55
__7______6.66
__8______7.78
__9______8.89
__10____10.00
Note that the pots used in guitar amps are notoriously poor tolerance and are "consumer" log taper. The Axe-Fx uses true log taper and the tolerance is perfect so there can be 10% or so mismatch at any given knob position.
Only tiny comment on that
A e.g Vibro Champ would not work on Fender "1" needs min 1.5 to sound at all maybe that is due the high efficient Oxford speakers
Roland
