From the vendor
Clone of the Spaceman Explorer phaser, but with a twist. We've replaced the original custom programmed LFO chip with the "off the shelf" StompLFO chip from Electric Druid. The chip not only allows retention of the expression pedal phase sweep input, but also offers more waveforms than the original design, as well as tap tempo and external sync input. Talk about a Cadillac upgrade! One awesome sounding phaser, with useful bells and whistles as well.
