Our authentic V-TONE modeling technology recreates three of the most sought-after classic guitar amps, with three gain modes and three mic placements for a total of 27 possible configurations. You get a truckload of great amps in one convenient stomp box, allowing you to go from clean or crunch to super-fat distortion in a flash.

Extremely User-Friendly
Operation is simple; just choose the type of amp, from the smooth Calif (Californian), the bright, punchy TWED (Tweed), or the BRIT (British) with its incredible sustain and aggressive mids. Then select the gain mode, CLN (clean), HOT or HI G (high gain). Lastly, choose the mic placement from the three available selections. This feature is a BEHRINGER exclusive, allowing you to place the "virtual mic" in any of three positions:

(OFF X) - At the edge of the speaker cone, producing a smoother, softer sound with less midrange content
(CNTR) - Positioned at the center of the cone, for more upper mids and beefy low-end
(CLSIC) - Slightly in front of the cabinet, for high midrange content with tons of definition

It's a Tone Thing
We've also included a dedicated Drive control, for adjusting the amount of gain. This control effectively mimics the amount of push applied to the output stage of a tube amplifier, 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 1/4" 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.
