Keeley produced the Verb O Trem with Nashville guitarist and song-writer Edie Heinzelman, and has designed the pedal ‘to instantly allow players to input the amount of Verb or Tremolo they need’.
The compact Verb O Trem offers three variations: the classic reverb and tremolo, Mack (pitch vibrato from a tube amp and spring reverb), and Harm (harmonic tremolo and spring reverb).
The larger Workstation version offers eight reverbs and eight different modulations. Reverbs on offer are 2 Spring, 3 Spring, Plate, Hall, Chamber, Room, Fugue and Slapback, while users can choose from a range of modulations including sine wave, square wave, harmonic, dynamic harmonic, pitch vibrato, ramp trem, ‘Les’ rotary speaker, u-vibe).
