​The Lunchbox Junior boasts astonishing power and versatility in an ultra-portable, 5-pound package. Capable of crystal-clear chimes, thick blankets of fuzz, and everything in between, this superb pedal platform has earned a sterling reputation for mid-volume gigs, home recording, and more. Drive your pedals with the 9V output, and add the ZT Battery Pack (sold separately) to play on-the-go.

The Junior received a Premier Gear award from Premier Guitar magazine in 2012.

“The size-to-volume ratio is nothing short of remarkable. There is a fantastic, tube-like warmth that you just don’t hear in many solid-state rigs…I heard a character-rich set of overtones and each note had a pleasing roundness.” -Matthew Holliman, Premier Guitar

“I’ve had situations where this portable amp would have been the way to go without giving up any tone. Frankly, I’ve been lugging around too much amp.” – Jake Kelly, American Songwriter 


“It sounds incredible. I’ll admit I wasn’t expecting anything from a tiny amp with an 1/8” jack, but man was I wrong.  Plugged a crappy Harmony electric into it and was blown away. That guitar never sounded so good.”
– Brendan Benson
