For Sale: Keeley 4 Knob, 6 Stage Phaser Another casualty of my Hail Damage Deductible Sale! 6 stage phasers sound the most funky to me for use with bass, thus why I owned this green boy for so long. The Keeley phaser is really nice, with an added Tap/Ramp feature that you don't see in most phasers. What's this do? Well one of two things: either lets you set a slow speed and a fast speed and ramp up/down between the two (think of a lesile effect) or tap out the speed of the phaser to match your song tempo. Don't have the box; there is Velcro on the bottom of the pedal. Price: $135 shipped in the CONUS NO TRADES!
