PG's Acoustic Editor Gayla Drake Paul walks us through her latest review of the ZT Amplifiers Lunchbox Acoustic, which is featured in the July 2010 issue. 

The Lunchbox Acoustic is ZT's first two-channel amp that features a top quality, dedicated microphone channel and separate instrument channel each sport the individual controls. It's loaded supported by 200W of clean amplifier power, anti-feedback circuitry, a pro-grade reverb and a highly flexible signal I/O.

The amp's controls are Gain, Bass Treble, and Reverb for each channel, a Master Volume, and a three-position anti-feedback control. It houses a 6.5" speaker and weighs about 12 pounds.

What a complete disappointment. I ordered this amp after reading Gayla's stellar review believing that it was 200 watts with a DI output, a woofer specially designed to handle large excursions for high volume applications, and a natural acoustic sound. The amp I received had none of these. I measured the amp power at about 130 watts RMS. The output jack that is labeled DI is anything but that, neither balanced nor transformer isolated. The paper woofer has a pressed paper surround not even a butyl rubber surround for response linearity as the volume goes up. And the sound? It's a modeled pre-amp stage but with no user access to the modeling parameters. I hear a guitar sound that some talented software engineers created to their liking in Berkeley CA. I don't hear the sound of my guitar as it sounds unplugged or through good acoustic amps that sound transparent. ZT is misrepresenting this product in their marketing and advertising -- not a 200 watt amp, no DI, no linear woofer response with increasing volume, and a contrived modeled sound. What surprises me most is that the professional magazine reviewers haven't picked up on any of this, except for a few who have pointed out that the amplifier is not as powerful as ZT says it is.

It would also be nice for online listeners if you could isolate the amp more. It's difficult to tell sometimes what's the guitar and what's the amp.

From what I hear in this video this liitle amp sounds better than the Vox acoustic amp. But the guitar for the Vox review was a Voyage-Air (a travel guitar).

Also what kind of pickup are you using on your guitar? This info is helpful.

Guitar sounds pretty good, but how about adding in some vocals. Or, better yet, a live event test with audience comments! Yeah, now there's a test! The next, best thing to being there.
