The DocDerr is a 500 Series multi-purpose tone enhancement module that houses six different sections of digitally controlled analogue processing. A low-noise preamp, capable of working with line level or instrument level signals, is followed by four sections of EQ combining a two position high pass filter with three parametric bands, each with its own set of carefully tuned frequency presets. An internal jumper can turn the DocDerr into an instrument preamp with 16dB of gain.

The EQ is followed by a dynamics section that offers renowned Empirical Labs compression and a tape emulation circuit that softens and tames high frequencies and transient spikes. The DocDerr’s Mix knob allows the user to blend the uncompressed EQ’s signal with the compressed and saturated signal.

• Six digitally controlled sections of analogue processing

• Frequency response – 3 Hz to 180 kHz on eq section (-3dB points)

• Dynamic range – 120 dB from max output (.5%THD soft clipping) to min output

• Guitar adaptor cable included
