So, someone in a thread mentioned that the guys from Red Wire impulses created this "speaker impedance curves" (no idea what tha means) and that one should put them before the cab sim impulses to make tube amps sims sound better or more like real tube amps. As you can tell, I know shit about this. This is Red Wire's statement:
[FONT=Arial,Helvetica,Sans-serif][FONT=Arial,Helvetica,Sans-serif][FONT=Arial,Helvetica,Sans-serif]This update includes impulse reponses of multiple speakers' impedance curves. These can be used to reproduce the effect that a tube amp can have on the frequency response of the speaker. Compared to solid-state power amps, tube amps have a high output impedance. As a result the connected speaker's frequency response will change, causing it to look more like it's impendance curve than when driven by a solid-state power amp. You may appreciate the more scooped tone, the added thump and sparkle.
The IR labeled "100perc" is the impedance curve as it was measured. Files with 90perc, 80perc, etc. represent "toned down" versions of the impedance curve for less of an effect, where 90perc is 90% "wet", 80perc is 80% wet, etc. 50% wet is equivalent to the real world effect we saw with many of the tube amps we tested. Speakers included: Celestion G12M25, G12T75, Vintage 30, Alnico Blue (more coming soon) [/FONT][/FONT][/FONT]
So, I gave it a go and I can tell it does sound different and nicer to my ears, but I don't know if I am doing this correctly. I tried it using Lecab. I'm sure someone can explain this better
edit: this is where I found out about this, it was Wild Hades from ignite Amps: http://www.ultimatemetal.com/forum/...-free-3-ch-tube-preamp-windows-vst-32bit.html
