We close out the 2017 NAMM show with a look at gear from DigiTech, Santa Cruz, Hamer, and more.

Singer-songwriter David Ryan Harris collaborated with Port City Amplification to create the Soulstice, a 50-watt amp with surprisingly manageable volume. It has a wicked pitch-shifting vibrato and dual 6L6 tubes. Plenty of clean headroom with just a little grit. He'll be taking a pair of these out on the road with John Mayer later this year. $2,950 for the head.
