Sorry it's gone. We may have another in stock or on the way. Please enquire below (or check our weekly Gear Update for incoming rarities).

“Poor man’s AMS DMX-16”? Possibly… but certainly if you’re looking for a pretty full-featured 80s digital ‘verb for a fraction of the price then this is worth considering.

Product Description

Klark-Teknik DN 780 Digital Reverberator / Processor for sale.

More than just reverb - this does some great reverse effects, as well as delay/double-tracking. Controls give access to all the usual parameters. Presets can be somewhat brash at times but it has memory space to store your own versions.

This page on has spec, sound samples and plenty of information about these units (including the familiar rumour that algorithms from AMS lurk within these - we have no further information as to the veracity of that, but certainly the two are sonically different. Like all (vintage) Klark-Teknik gear this is generally high quality, interesting and pretty uncommon.

Has just been serviced by a digital specialist and is working well, including the fan which can be a weak point on these - just ensure it is not covered during use!

Mono in, stereo out on XLR.
