The ZT Lunchbox Acoustic is the most lightweight and compact pro-quality 2-channel acoustic guitar/vocal amp on the market today. Players frequently comment that the Lunchbox Acoustic is the most natural sounding acoustic amp they have ever used. ZT went to great effort to achieve this result, careful to avoid coloring the instrument's sound, and instead making your guitar sound like your guitar - just louder. And by utilizing the amp's power to assure the low frequencies so important to acoustic guitars remain strong despite the 6.5 inch. speaker size, ZT succeeded in making the Lunchbox Acoustic sound much bigger than it is. Individual controls for the dedicated microphone and instrument channels combine with clean, room-filling amplifier power, anti-feedback circuitry, a pro-grade reverb, external speaker output, and an effects loop for plenty of flexibility. You can even add pre-recorded tracks via the 1/8 inch. aux input. There is simply no other amp as easy to transport & gig with than a ZT amp, and for the acoustic player, it's the ZT Lunchbox Acoustic. Features 6.5 inch. speaker and 200 watts
