EMPIRICAL LABS DocDerr EL-RX DUO - 500 Series - Multi-Purpose Tone Module (Horizontal Pair in EL500 Rack)

The DocDerr EL-RX DUO from Empirical Labs is a horizontal pair of multi-purpose tone enhancement modules preinstalled in the EL500 rack that houses six different sections of digitally controlled analog processing. The DocDerr features a low-noise preamp capable of working with line level or instrument level signals, 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 unparalleled instrument preamp with 16 dB of gain, great for acoustic guitar, bass, synths, exotic plucked instruments, and more.
