I have had a VB-2 since last Nov. LOVE IT! Although i haven't been able to find a tour 410 cheap enough for my liking so i went with the back breaking(but cheap) TVX 410 and it sounds huge! I will take some shots of it tomorrow at practice and share. Stay classy TB.![]()

The mid shift shifts the whole EQ. If you use the 200Hz setting, you also shift the low and high control active centers to their lowest points so you don't end up with EQ dead spots. This can make it easier to pinpoint and boost deep bass. This shift also moves the mid control into the "punch" EQ range, effectively turning the mid control into more of an upper bass control, but the mid control boost is wide range, so you will still have control over the higher mid frequencies.
Basically, the resonance control increases the power amp's low frequency gain as you turn it up. This can be thought of as a "loose" control, but it can also be thought of as a power amp bass control. This is accomplished by altering the feedback, or error correction system in the power amp, which looks at what's coming out, compares it to what's going in and makes adjustments accordingly. Your bass cab may say that it's 8 ohm or 4 ohm impedance, but actually, cabinet impedance changes with frequency. Without going into too much detail, these impedance variations can cause "error" in the speaker/amplifier system that is your rig. Error can mean a bass resonance, or bass hump that is inherent to the cab design. Feedback in a power amp can allow the power amp to dampen out these resonances to hold the frequency response flat, which is often desirable, or feedback can be used strategically to encourage resonances, also sometimes desirable. Presence does the same thing except to the highs.

That's a good cab to use with the VB-2. It was voiced with that cab and the Pro410. I use the TVX as my office test cab. It may be inexpensive, but I like 'em!
