Aha!Is there a chance you disabled the update impedance curve on legacy patch load global setting, and were noticing legacy patches that didn't update to their new default?
Let me try to answer you:This curve is specific to a cab and speaker, this calls for philosophical/methodological question regarding amp modeling block:
1. Could the impedance curve considered part of the cab and speaker modeling as well?
2. I wonder if the IR already captures some of the impedance curve information, does that overlaps with this part of modeling...?
3. If one can capture speaker and cab characteristics well enough, would it make sense to model the cab and speaker out-right and make it an alternative to IR player instead?
The current Cab blocks does IR, smoothing, proximity, mic pre-amp modeling, which seems have a lot of overlapping with what's captured inside the IR already. Maybe it makes sense to separate cab from IR player...
I'm with you, it's a purpose-built parametric eq, with a bunch of reality-based preset starting points, great tool. It don't always tweak the curve, but sometimes I definitely do exactly the things you said, tame boominess or excess highs. Lots of ways to adjust this box...I almost always tweak this, the low end could sometimes be boomy, and I need to shrink the low end peak a bit. And for warm jazz tones, I often tilt down the high end. This is one of the most effective tools to deal with boomy IRs...
Interesting situation, if I convert Axe-FX 2 preset to a 3 preset, the default seems to be reactive load.I think you're wrong about this. I checked every amp model and NONE default to anything other than a speaker impedance other than the Tube Pre.
Yes that's normal behavior because it doesn't exist in gen2 and default value at index 0 is réactive load i guess
if you import an old preset via Fractal sometimes you get th eractI've found the Texas Star 2x12 works well with my preferred IRs... But sometimes others work better with different amp models.
Any time I try new IRs I'll try out some of the different curves to see what sounds best.
Sometimes a different curve can do wonders especially in the bass response.
Also, some of the amps default to reactive load, which isn't likely "authentic".
Yes, I found the same.
Totally agree. Not only for the bottom end, but for the high end where the bite can be too much for some cabinet, not enough for another. Changes the "feel" or response of the amp in those areas in a different way than just adding or removing the frequency.I LOVE the speaker impedance curves. Spent a LOT of time with them in making the Live Gold presets, just trying various speaker impedance options out (not just default) with various Cab IRs, until it felt and sounded right like amp-in-a-room to me. They can be just the thing that wakes up the amp if you are struggling with dialing it in.
These really help help get the bottom end "just right" when using/auditioning different IRs. Huge leap forward when these preset curves came along for the speaker page!
Kudos to Cliff for making this part of the amp block.
You can try 1 X 12 V30 or the 2x12 Lead 80 and see what you think...Hello Everyone,
Which is the best impedance curve to select for a Carvin Legacy amp block? the default is pointing towards 4x12 USA lead, where as the suited IRs are all 2x12 leggy's, so how come it is pointing to a 4x12 Mesa model?
Anyone has any more information? As far as I remember the imp curve was added (FW 9 onwards I assume) where as the legacy model is very old and has never been updated.
Havent seen or heard any comparisons for the Vai model with the original legacy model like we usually see comparison with other models, hence cant understand how close is the modelling compared to real legacy amp.
Can anyone help to shed some light?
