Kevin Frazier from Grid1 recently let me know about his company’s new product: a 60 watt lithium battery-powered tube amp called the G1 BPT212. The amp was launched at the Winter NAMM show in Anaheim about a week ago. It features 2 12″ speakers, a lithium rechargeable battery, two footswitchable channels, and your choice of wood cabinet. The company claims to get 4-6 hours per charge. Frazier recently demoed the amp for Guitar Player magazine. The G1 is expected to ship in February.
