The WA2A Optical Leveling Amplifier makes any recording sound better, drastically. I purchased a pair of these from zZounds, excellent customer service over the years, and since putting in over 100+ hours on the WA2A's I can say that these units actually work extremely well. I run my guitars through them, vocals, drums, bass... everything, and there's just something to hear about the difference these make. Comparing recordings without using the leveling amps, they sound mediocre. Plus, I am going to run all of the tracks through the WA2A's at the end as a master, and I am excited for the results there as well. These units are very functional, yet easy to use. Finding the sound is just plain easier with fewer knobs, especially if you let the tubes to the talking! BTW, utilize the "Pre-emphasis" knob on the back to alter the harmonic distortion of the tubes. It's a little difficult to reach in most setups, but dial it up to 3/4 up and that's a good start. Something that I've noticed, heavily distorted guitars sounds real nice with the Peak Reduction turned up fairly high, careful now! All in all, great product. Should last a really long time. P.S. They come with a pret-ty cool sticker.
