VT Bass frequency response plots

#41
Also, these were done with the gain at minimum. At the halfway point it seems more toppy which is why some roll their treble all the way down when using it as an overdrive.

Going through to headphones/monitors at medium-high gain I need to have the treble down very low. If I'm using it more as a straight up amp/cab sim after fuzz with the gain set low, then I set the treble to the 'flat' position of 10:30 o'clock.

I just bought my VT two weeks ago and they may have changed it up a bit. To get a flat signal all my settings are the same except High is turned all the way off and unity gain is at about 2 o'clock. Seems kinda odd, right?

Also, my Mid seems to be tuned to around 1.15k (or at least the resonance is right there); nowhere near 500 as mentioned on the insert. It's right around the frequency of my pick attack. Has anyone else noticed this?

Was there more than one version of this pedal ? I'd love to know. For me, unity gain (with no drive, i.e. drive set to 7) is with level set to 2:00, but I'm finding it a bit of a nuisance to trim the level around 8:00 when using higher drive levels ... tiny tweaks make a huge difference in volume.

As regards mid frequency, the other thread strongly suggests the same thing as you, it's 1K. Maybe the insert was always wrong ?

Thanks for posting that other thread, but honestly, I didn't understand what any of it meant. Lol, I just really understood the mid frequency being about 1k, but all those graphs went way over my head...

I actually got a lot from your graphs. I have an approximate idea of how to set the EQ relatively flat wherever the character knob is, which is awesome. Thanks again

I just downloaded FDeck's RTA software and have been messing about with it. I did a few screenshots of the VT Bass at various settings for anyone who's interested. The aim was to see if it suffered from the same mid-scoop as the BDDI, how flat the EQ was with the EQ knobs at noon, and how to get the best approximation to a flat EQ.

Character all the way down, all EQ knobs at 12 o'clock:

Finally, I managed to get the flattest curve possible withthese EQ settings (apart from the massive treble rolloff due to the speaker sim!):

Wow, stuff like this is why Talkbass is freaking cool.
