iPhone applications developer Agile Partners asked TESTAMENT guitarist Alex Skolnick if he would run through a setup using the all-new stereo delay coming in AmpKit 1.6 (an amps, effects and recording app for iPad, iPhone and iPod Touch). The recording below, which was captured by Premier Guitar at this year's NAMM (National Association Of Music Merchants) show, a massive music-products convention that took place January 24-27 at the Anaheim Convention Center in Anaheim, California, features Alex on the developer version of AmpKit 1.6, which will feature stereo output capabilities. Alex is hooked into a Peavey 10-channel mixer, which is then going out to two Peavey 12D powered enclosures. The audio you hear was made from a digital recorder hooked to the output from the mixer. No EQing or mastering has been done to the AmpKit audio track. Some ambient sound from the camera mic has been added.

Skolnick is one of the true guitar heroes. He has performed in some of the world's biggest venues with his seminal thrash metal band TESTAMENT, and relocated to New York City to earn a jazz degree from the New School. He has recorded four albums with his acclaimed trio, including his most recent, "Veritas", out now on Palmetto Records.

TESTAMENT's new album, "Dark Roots Of Earth", sold more than 20,000 copies in the United States in its first week of release to land at position No, 12 on The Billboard 200 chart. The CD arrived in stores on July 31, 2012 via Nuclear Blast Records.
