• NSL Spring Reverb

Signal Chain


This library features recordings created using a "Knas Ekdahl Moisturizer", a boutique spring reverb effects unit where three reverb springs are exposed, allowing them to be hit, played, and manipulated in real time. The unit also includes a multi-mode analog filter, and when combined with the playability of the springs, opens up many sound creation options.

The result is a unique sound effect library of massive metallic hits, clangs, scrapes, plucks, bounces, and rattles. The springs were played like a percussion instrument, using a collection of found objects, such as hammers, mallets, allen wrenches, forks, and plastic / metal rods. The springs were also stretched to alter the pitch, and objects were placed on the springs, much like a prepared piano, to alter the sound.

No other effects were applied other than the built-in multimode filter (high pass, low pass, band pass, and resonance) on certain sounds. These include sub-sonic hits, sweeping filtered metallic scrapes, and drones that round out the collection.

High-end outboard gear was used to capture the sounds in pristine high resolution quality. The output of the spring reverb was recorded DI to a Neve 1073 preamp, to a Apogee Rosetta 800 A/D converter and then into Pro Tools HD at 24bit, 192khz.

All sounds in this release are offered in 24bit 192khz Broadcast Wave format. Files are in a zip file, which includes a PDF with metadata.
