Keeley Caverns Reverb & Delay Pedal - Review & Demo

As you might expect from a pedal designed by Robert Keeley, the Caverns is no ordinary Reverb or Delay pedal, offering huge scope for tonal tweaking allowing you to create huge, lush, ambient soundscapes, whilst still remaining simple, intuitive and inspiring to use. The pedal’s split into two halves, on the left is the Reverb and on the right the Delay, and you can toggle these on and off individually using their corresponding switches. The delay side has controls for delay time, ranging from thirty to six hundred and fifty milliseconds, there’s a feedback knob to set the amount of delay repeats and a blend to adjust the mix between wet and dry signal. The delay itself is derived from Keeley’s much loved Magnetic Echo circuit, so it’s designed to emulate a vintage analog tape machine, so to add a bit of colour to the tone there’s also a modulation switch, to add virtual tape wow and flutter to the delay repeats. This is switchable to either light, deep or no modulation, and the speed of the effect is controlled by a rate knob. There’s three different reverb modes to choose from. Spring mode offers a lovely vintage, Fender Blackface style spring reverb and tremolo effect, Shimmer mode puts an emphasis on octave up harmonics and modulation mode adds a kind of chorusy modulation to the tone to create a huge, cavernous sounding reverb. These are then controlled by knobs for reverb decay or time, reverb warmth, from nice and bright to muddy and dark, and a rate control...
