“BPB Dirty Spring is a simple plugin designed to sound good out-of-the-box. It’s easy to use, too. Adjust the Decay and Tone knobs to get the desired spring reverb character. You can preview it by pushing the Kick button (it simulates kicking/hitting a hardware spring delay).
The Pre knob adjusts the pre-delay time, which can be used to achieve some interesting echo/delay effects.
BPB Dirty Spring’s “secret sauce” is the built-in bitcrusher. Placing a bitcrusher on reverb isn’t everyone’s cup of tea, so the feature is completely bypassed by default. However, I love crunchy-sounding spring reverbs, and I highly recommend giving this feature a try.
There are several bitcrushing modes to choose from, ranging from very subtle to over-the-top. Try using some of these on sampled drums to get that classic 8-bit sampler effect.
Use a short Decay setting and adjust the Mix knob so that the bitcrushed signal is just a subtle lo-fi layer. Or, crank up the Decay and enjoy the sound of an extremely lo-fi spring reverb.
BPB Dirty Spring is free to download and use”
