16 Studio Quality Effects Options

No matter how "minimalist" a guitarist is trying to be, they'll nearly always opt for Reverb and Tremolo effects on their pedalboard.

The Keeley EH Verb O Trem Workstation gives players a simple and beautiful sounding way to round off their board, bringing together those famous Keeley spring and plate reverbs with modulated valve-amp tremolos.

Two Flowers, Each With Eight Petals

This high-end Dual DSP effect workstation is packed full of studio-quality sounds that Keeley have developed tirelessly over the years, with each effect circuit having their own engine and set of controls.

You have a whopping eight effects of each type to choose from:

Reverb Effects

  • 2-Spring
  • 3-Spring
  • Plate
  • Hall
  • Chamber
  • Room
  • Fugue
  • Slapback

Modulation Effects

  • Sine Wave Tremolo
  • Square Wave Tremolo
  • Harmonic Tremolo
  • Dynamic Tremolo
  • Pitch Vibrato
  • Ramp Tremolo
  • Rotary
  • Uvibe

Each circuit comes with indepent controls for output level, alongside controls unique to that particular effect type (such as Decay, Morph and Effect Level for Reverb, and Rate, Depth, and Morph for Tremolo).

This allows you to create a near-endless blend of both effect-types, each of which also has its own independent activation switch - so you can have just reverb, or even just tremolo activated at any one time.

Custom Artwork

As per Eddie's request, the Keeley EH Verb O Trem Workstation features a lovely Lotus Flower print on a cream background. Not only does this add to the pedal's aesthetic charm, but it also has a spiritual meaning too.

Eddie chose a Lotus Flower because it represents the search on a path to enlightenment (in this case: your musical journey). The cream background is for the pinnacle in achievement, whilst the deep red linework is for the passion involved in such an endeavour.
