Something preamp modeling related?Ima cookinga something upa.
LOL, how did a couple weeks become several weeksSeveral weeks with this one, wonder what cliff is cooking or maybe he decided to take a well deserved holiday lol

Are the preamps already not damned AMAZING enough?!?!?Something preamp modeling related?
The power amp modeling is truly amazing! I personally feel like there is something in the bass/lower mids response of the preamps that is not entirely on par with a tube preamp. The best way I can describe it is that the tube preamp responds more precisely - like there is more roundness to the note and that the character of the unamplified note is better preserved. (I compared the preamp signals of my JVM and the Axe through a power amp model in the Axe). It's not really audible, more of feel thing, especially when going through the power amp + cab setting. I was hoping that the power amp FASPICE magic can be applied to the preamp triode models (I might of course be mistaken and it already is).Are the preamps already not damned AMAZING enough?!?!?

Kudos to @shatteredsquare for pointing you in the right directionThis is what I've been working on:
Firmware 11.0 introduces our new high-order speaker impedance modeling. We've curated the impedance data from nearly 50 cabinets. You'll now be able to select the impedance curve to use with an amp model (selecting an amp model loads the most appropriate curve for that model).
Why is this important? When you look at speaker impedance curves they look pretty simple. However that data is obtained when the speaker is mounted on an infinite baffle. As soon as you mount the speaker in a cabinet that impedance data changes, sometimes quite radically. The modes of the cabinet introduce significant peaks and dips in the impedance due to the back EMF created. Some of the cabs we measured have deviations from the published curves by 4-5 dB or more.
To understand why this happens the impedance of a speaker is dependent upon the acoustic load. In an infinite baffle the load is constant. Put the speaker in a box and the load is greater at some frequencies and lower at others because the sound waves bounce off the walls and constructively or destructively interfere with the motion of the speaker. For example, consider the sound emanating from the speaker and bouncing off the back wall of the cabinet. When the sound wave reaches the speaker it will either aid or oppose the motion of the speaker. If it aids the motion then the impedance will be lower and vice-versa.
I hope to have a beta this weekend.

Does this mean old presets will sound different?This is what I've been working on:

This seems like it's a step towards implementing a long standing wish to correlate cabs to amp models in the unit in some more automatic way?Firmware 11.0 introduces our new high-order speaker impedance modeling.

No beta for you!Kudos to @shatteredsquare for pointing you in the right direction
