Everything from retro-style axes to interstellar effects and insanely powerful amps caught our eye in Nashville.

Park Amps brought two really nice-sounding heads to NAMM. The Little Head 18 (top) uses the same preamp as the venerable P45, but has a rad self-biasing power section that accepts 6V6, 6L6, EL34, and other octal tubes—including rectifiers—without modification. Meanwhile, the EL34-powered, two-channel Rock Head 50 was inspired by the '70s Park Rock Head, but adds extra flexibility with a switchable cascading gain stage, and a cathode-following tone stack.
