I mean, there's nothing above 10kHz. I really wouldn't have expected that.
Yes, I was surprised too.
This is why, if you do not change any setting the sound is really darker when you cut the cab sim.
As other informations I tried too reach the flatter responses with the speaker sim on and the speaker sim off, because It's interesting to do that with different values of the character.
With the Cab Sim On
, it's not easy, and with some values of the character it's impossible : you have to live a light mid scoop or a boost of the highs :
With the Cab Sim Off
, it's more easy :
What is really interesting is that you can keep a flat signal but change the cut in the lows just by boosting bass, mids and trebles in the good way.
I don't put all the other measurements to see what frequencies are affected by the different knobs. I mean, someone already did that very well (with nicer curves than me
in that thread Tech21 VT-Bass - where's the magic ?
So yes, in term of frequencies, the Speaker sim of the VT seems to only boost the highs.
After that, there are maybe some other more changements made in the tone by the speaker sim, but they may be subtle.
Anyway, it's a very nice pedal, even if its understanding is not immediate
You have you have to earn its great tones !!
