Subject:Re: Finally revealed, new tool eliminates the "shrill factor"

I have the 3 closed sides, to keep the sound balanced as a keyboard
amp, as this is more a keyboard amp than an actual leslie. For a live
gig, it will be mic'd. I have it enclosed, to get a rich rotary tone
out of the horn. The high end response didn't really kick up as you
suggested, but more pronounced in the reflections moving around inside
the cabinet, which sound quite nice. The DEQ, simulates the "loudness
robbing effet" then to the preamp, and then to a final tone-shaping EQ
to get a close response to a Leslie cabinet power amp and speakers
frequencies response.
On the 2101, I have the horn volume turned up almost 100% for a few
reasons:
1. the crossover area for the lower rotor sim is wrong (permantly set
at 1000hz.... I tested it myself to be sure) I have the horn X/over
at 700hz, but still the lower rotor sim overpowered it at around 1khz.
Putting an 800 hz test tone, I turned up the horn volume until the
800hz tone just barely edged up above the low-rotor level.
2. With the above settings on the 2101, I bring in the final EQ module
just before the 2101, for final tone-shaping, and fine-tuning the high
end spectrum to get a clean balanced signal to the horn driver, as
well as shore up some deadened frequencies on the lower rotor-sim (I
use the cabinet resonance, which I think sounds cool) to smooth out
the lower end. The EQ tames down the preamp drive effect, so it
sounds smoother (like hot-run 6550's although not quite the same)
overall organ tone and overdriven tube tone.
Its kinda hard to explain better here with words alone... my next
video will detail how I route the signal the way I do. I still have
some fine-tuning to do, but I'm very pleased how its going, and never
thought my VK8m would sound this good!
BTW.... referencing Ted's comment "there's another way to deal with
the 'shrill factor'" I have to partly disagree... I'm not going to
start a war in that arena, but I can say that my method will make
Ted's alternate solution sound even better!
