Great Sound, Naturally

By their very nature, piezo pickups tend to
be very bright, with somewhat reduced bass
response and warmth. The ADI21 combines
the features of an active DI (direct injection)
box with our proprietary microphone/tube
emulation. The BLEND control allows you to
mix the amount of modeled tone with your
instrument’s normal output. The resulting
sound is more natural with smooth saturation,
just as if your guitar were being mic’ed in the
great outdoors.

EQ and More…

Armed with an onboard 3-band EQ, with
sweepable mids to keep feedback under
control, the ADI21 e ectively eliminates the
harsh harmonics of piezo pickups. The output
is laid out on ¼ " TS or balanced gold-plated
XLR connectors, which can be used to send a
low-impedance signal to the mixing console
or straight to tape. You also get a ground lift
switch to eliminate annoying ground loop
hum problems. You can power this little
lifesaver with a 9 V battery or our PSU-SB DC
power supply (not included).
