It’s a Tone Thing

We’ve also included a dedicated Drive control,
for adjusting the amount of gain. This control
e ectively mimics the amount of push applied
to the output stage of a tube ampli er, from
a gentle nudge to full-out, tube-melting
overdrive. Further tone shaping is provided by
a highly musical 2-band EQ.

Versatility

The GDI21 can be used for direct recording output, with speaker simulation or, when used
in bypass mode, as a superb active DI box. A ¼ " output jack is provided for connecting to
your amp and the gold-plated, balanced XLR connector will link you cleanly to the front
of house console. Ground loop problems are nonexistent, thanks to the onboard ground
liftswitch.
