Anyone who has Source Audio’s Nemesis Delay and Ventris Dual Reverb on their pedalboard has a pretty comprehensive arsenal of ambience effects underfoot. 

Now you can access that experience while bypassing the combined price tag and footprint: the new Collider puts seven reverbs from the Ventris and five Nemesis delays into a single dual-engine pedal for a more streamlined pedalboard.
