Korg DRV-1000 Digital Reverb, used
The DRV-1000 is a classic, early digital reverb from master keyboard makers Korg. Designed in 1985, when it was essential for product names to sound high-tech & futuristic, Korg pushed the Go button on their newly-installed PNG-3200 Product Name Generator* and came up with DRV (for Digital Re Verb) and 1000 (for esoteric modernity).
The front panel is super-simple with input & output controls, normal & signal overload LEDs, 8-way pattern selector and an 8-way reverb time selector. Final controls are High Damp & Cancel switches. High Damp affects the liveliness of the high end, to mimic the typical high frequency fall-off found in well-damped rooms. The Cancel switch kills the reverb signal, leaving the original signal dry, and this can also be operated via a footswitch
