Outsstanding bang for buck
I prefer the VLA 1 to the more popular 2. Its a little less hifi sounding for starters, the tube stages are grittier which is great for parallel bus use and its got a fast and dirty like it or lump it fixed or program dependent attack and release system that makes working with it fast. You want fidelity and precision get a 2, but if you want something that excels at trashy special effect jobs? This is it. Don't expect an LA2A, expect a stereo unit that can make anything sound like zep.... just kidding, but its got this loose vibey thing. The differences are minor between this and the 2 but its worth having both at these prices as one is clinical and precise and the other is a budget mojo machine. They can be made to sound similar but never the same.... both versions feature a big dollop of output that can be used to overload a console bus. Remember to back off those faders once you're in the red, kids. This baby gets LOUD
HEADS UP, the VLAs aren't in starved plate but they're not high voltage tube circuits, its more sort of a hybrid opto, slid state does most of the real work for in and out amps. Don't expect an LA2A but it has a vintagey charm of its own...
