HoRNet Plugins has introduced a free physically modeled spring reverb.

A simplified version of the HoRNet SpringVerb, the new Molla effect plugin uses the same algorithm to recreate the complexity of the physical interactions between the springs and the sound taking place in a spring reverb.

In a spring reverb the reverberation effect is generated through an electro-mechanic stimulation of one or more springs at different tension. The spring(s) complex oscillations are then converted back into electrical signal by pickups.

The spring reverb was born together with plate reverb as a mean to create artificial reverberation in the 30s and was made popular by Hammond organs which adopted this kind of reverberation due to its small size. This factor also lead to the adoption of spring reverbs from many guitar amplifier manufacturer and, despite not sounding like a natural reverb, its metallic and dark sound has become part of the recording history for many musical genres.

Like with the SpringVerb, we approached the recreation of this peculiar sound implementing a mix of research papers and adding our own twist but, we have packed the attitude, the sound and the flexibility of our SpringVerb into a smaller format that is simple to use.

Available in VST/VST3, AU and AAX formats for Windows and Mac, the plugin is free to download in return for a social share.
