Mid Shift switch on Peavey VB-2

walknbluez · #1 07-27-2010, 11:50 PM

The Peavey VB-2 has three active EQ controls: Low, Mid, and High. It also has a Mid Shift switch. The manual states that this switches the center frequency of the MID control between 800, 600, 400, and 200 Hz.

I was playing in a rock trio where I liked to get just a tad bit of overdrive, particularly when I played double stops. I usually kept the mid shift switch at 600. Now I'm playing in a project where I want a cleaner, "tighter" tone.

So I'm confused about how this mid shift control actually works and how it may help (or not) to dial in the tone I'm looking for.

I'm playing a Fender P and Fended Jazz through the VB-2 and an Avatar 212.

Am I correct in thinking that I will get tighter, cleaner lows by going with a lower setting on the mid shift switch, i.e. 200?

Sorta...picking a low mid shift setting & boosting will give you more low-end.The higher you set the mid-shift the less lows. If you want a fat clean tone just dont use any overdrive.You can set the mid-shift anywhere just dont overdrive the amp & it will be clean.

the mid shift switch does just that, it shifts the frequency that the mid range knob boosts or cuts. The vb2's tone control is also set up so that the bass frequncy moves up and down as well.

For example, if you put the mid switch at 200, then the bass is at 50. Move the mid select up a notch, and the bass moves up too, to 70. The treble shifts as well.

Ok so how do we get 50 hz from 200 hz switch select? And even if I don't need to understand that, what is the significance? I know 50 hz is a lower frequency right? So is that "tighter" or more "boomy"?

Your gonna have to find a sweet spot of the amp.If clean is what you want then dont use any overdrive.Boost the low freq around 200hz or lower depending on your cabs ? And yes 50hz is a low freq but doesnt mean that its going to be nice & clean, it could be muddy & boomy.Setting the freq up higher will give you more mids & your bass will cut through more in turn giving a cleaner sound ? You can set the M`S as high as it goes & still get a clean tone.Just give it a go & listen with your ears.
All the best.
