Greetings everyone and welcome to my website Vettaville. This website is dedicated to providing unique information about some of Line 6's modern guitar/amp technology...particularly the Vetta as well the Variax. Also visit the Netherlands Vettaville and join us for equipment discussions at Andy Z's Institute of Noise Forums.

This article will be short and to the point. Let's face the music, the Vetta can be one complicated beast to work with...but that's also its inherent beauty.  And while Line 6 has done a great job of modeling so many different amps, cabs, fx, and mic options, trying to dial-in that elusive tone can be both frustrating and rewarding. If you feel that the Vetta sounds too boxy, boomy, bass heavy, etc. and are wanting to know which frequencies to adjust when using a "specific" cab model, then check out the list below.

  
   
 

Please keep in mind that since the Vetta's 4 Band EQ only provides two bands of fully parametric eq, you will not be able to adjust every frequency listed, so use whichever frequency comes closest. Therefore, my strongest suggestion is that you first focus on the "cut" frequencies listed below which tend to be the most offensive. I've chosen only the following cab models because I believe they will be the ones most often used.

The frequencies listed below are the "natural" resonant peaks and valleys for each cab model listed and could stand to have a little sonic surgery (cut or boost at those frequencies). These frequencies still apply regardless if you have chosen a 2x12 or 4x12 Output Setting. When using the Vetta's 4 Band EQ, I suggest a middle-of-the-road setting to start with, which means dial in the frequency listed with a Q=0.7 and about -6dB Gain Reduction. Then re-adjust according to your tone needs...and remember, it may only take just a little adjustment to make for a drastic change, so don't over do it because you can suck the life out of the tone as well.

If you wish to print this frequency listing, simply drag your mouse across the text and copy/paste it into a notepad or publishing program.

Specific Frequencies To Cut or Boost with the Vetta 4 Band EQ

2x12 Zen Master - cut@263Hz / slight boost@640Hz / boost@2.6K

2x12 Blackface   - cut@73Hz

2x12 Line 6        - flat frequency response, no changes

2x12 Match        - no good suggestions

Without going into all the technical details of the process, by sending pink noise into the Vetta and using spectrum analysis software, we are able to plot the frequency response of each Vetta Cab so that we can actually see how each cab model is re-shaping the frequency spectrum of the overall tone. After looking at all the different response plots, I've centered in on the "key" frequencies for each specific cab model listed above that should be addressed when applying EQ.

  
   
 

The image to the left shows two response plots, the upper lighter green line shows the flat frequency response of our pink noise test signal, while the lower bold green line shows the frequency response of the Vetta's 2x12 Line 6 Cab model...which by the way, is the least coloring of cabs simply because it has a flat frequency response.
Now this response plot shows how drastically a cab model can reshape the overall sound. As you can clearly see, this cab model is far from having a flat frequency response. Could you have guessed which cab model this is? It is the 2x12 Mini T, which explains why it sounds the way it does, and why it is very seldom used because it reshapes the over all tone in a drastic and not too pleasant sounding way.
