Turn down the lights, turn up the spectrum...Join Keeley Electronics' grand entrance into the hallowed halls of psycho-acoustic processing - the Aurora Reverb. Few effects complement a guitar better than reverb; from spring reverb coils in a tank to the distant echo of cathedrals to 600 pound sheet-metal plate vibrations. Reverb captures our imaginations and plunges us deeply into our musical psyches. Reverb IS the key to the highway.
