Here’s one of the first demos (by Mike Hermans) of the new Keeley Caverns V2, a 650ms delay featuring spring and shimmer reverb and also a modulated reverb mode.
From the manufacturer’s website:
The New Caverns Delay Reverb V2 dual effect pedal combines delay and reverb for the perfect end to any pedal board. It features Keeley’s analog style tape delay with modulation options. The 650ms of warm delay combine with Spring, Shimmer or Modulated Reverb. Now with True-Bypass or Trails option. Because of its small and compact design, the New Caverns is a perfect fit for any fly-rig or small board where you have tight space requirements. The New V2 features Keeley’s most popular time-based effects, blended perfectly and fine-tuned over 2 years. It will be an amazing addition to any board. – More info here.
