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.

Zach loves his Sovtek Mig 60 head, which he plays through a cab he built himself at a pipe-organ shop in Denver. Every glue joint is lined with thin leather for maximum air tightness, and it’s stocked with Celestion G12M Greenback speakers.
