The Keeley HALO Andy Timmons Dual Echo Signature effects pedal captures the mysterious sounding "Halo" that Timmons is known for and has long kept secret. Notes from the HALO dance rhythmically, almost creating a reverb-style diffusion. Those notes are held together with tape-style effects like modulation, saturation and compression. In addition to coming with Andy Timmons' signature delay tone, you can program your own sounds and save them as presets—easily bounce between Side A and B on the fly, essentially giving you two delay pedals in one. Experiment with the HALO's numerous other rhythmic delays, including quarter note, dotted 8th, stereo rackmount analog delay and a vintage multi-head tape echo. Stunning stereo and pristine sound quality are further enhanced with controls for saturation, tone and shelving filters.
