The External Speaker Output:
There is a ¼” external speaker output connector on the rear of the LUNCHBOX
Acoustic
, which
can be used to power an external cabinet. Please note the following IMPORTANT rules:
• The LUNCHBOX
Acoustic
is not designed to power both internal and external speakers
simultaneously. The external speaker output will not operate unless SPEAKER switch is set
to External.
• This output is fully balanced and high power. Connect it only to a passive speaker cabinet.
• Do not use this output for recording or connect it to other amps.
• Use a speaker cabinet rated at 8 Ω, or higher.
• Be sure your external cabinet can handle at least 100W.
Using The LUNCHBOX
Acoustic
With Other Instruments:
The LUNCHBOX
Acoustic
Instrument channel is not just for acoustic guitars. In fact, the
LUNCHBOX
Acoustic
loves a very wide variety of instruments and sound sources. Excellent
results have been achieved with electric guitars (especially with jazz tones!), slide guitar,
harmonica, electric piano, sax, accordion, electronic organ, traditional string instruments, and
synths.
Start with the GAIN, BASS, TREBLE, and REVERB controls all set at midpoint, and the VOLUME
all the way down. Then inch up the VOLUME, step by step. Season to taste. Because of the high
available gain, some acoustic instruments may tend to feedback if the GAIN control is accidentally
set too far up.
Mic’ing The LUNCHBOX
Acoustic
:
When making a recording, or running through a house PA, a great sounding amp really deserves
to be mic’d. Direct feeds are convenient, sometimes necessary, but they rarely capture the full
tone the player is hearing. Like all ZT products, the LUNCHBOX
Acoustic’s
sound is a result of
a synergistic system, and the internal speaker is an important part of that system. Getting really
good recordings always involves experimentation, but here are some general tips:
• Start with the microphone directly in front of the driver’s dustcap, about 6” back from the
grille.
• Cardioid LD condensers are the first choice, if available.
• Cardioid SD’s are good, too.
• An Omni SD can capture a very accurate sound, but you might have move it in closer to
the grille, and play with side-to-side positioning. A spot about halfway between the center
(“dustcap”) and the outer edge (“surround”) of the speaker will often work well.
• The classic dynamic guitar amp mics can work, of course, but be prepared to try a variety
of setup positions to get the tonal balance you want.
