{"type":"firestarter.listing","listing":{"id":"lst_hEZojswI","product_name":"Twin Lazers K1","category":"Guitar Effects Pedal","description":" \nNew for 2026:-Brighter LEDs!-Soft Touch Footswitches!-Tap-Tempo Footswitch!\nInspired by the long standing king of dual phase-shifters, this is true-stereo phase shifting at its finest.\nTwo fully-independent 4-stage or 6-stage phase-shifters (4-stages per phaser in Green mode, 6-stages per phaser in Red mode), can be run independently in stereo, or chained together via a standard patch cable to double the stages for series-mono 8-stage or extra syrupy 12-stages of phase-shifting swirl.\nPhase oscillator rate is displayed via a pulsing LED indicator adjacent to the Rate control and cycle times range from a crawling 0.2Hz (5 second cycle) - 5Hz (200mS cycle) on the dial.\nThe Shift control affords a phase shift/lag of between 0° - 180° between the dual phase-shifter oscillators.  When set at 90° in a stereo rig, the sound is truly mesmerizing as the swirl seems to be rotating around you, yet impossible to discern whether it is rotating clockwise, or counter-clockwise.  When the Twin-Lazers is run in series, a whole new world of phase sounds await by simply adjusting the Shift control.\nA full Mix control allows even more options and sounds allowing for light swirl, or full, thick &amp; ooey-gooey phase-modulation.\nA preset is easily saved by pressing the Save button, and recalled by holding the Tap-Tempo/Preset footswitch for 1.5 seconds.\nAn expression pedal can be assigned to any or all controls on the fly by simply connecting a standard expression pedal and rotating the desired control to the maximum setting (EXP. marker) on the dial.\nUsing Tap-tempo extends the oscillator speed out to a whopping 30-second maximum cycle, and a standard external tap-tempo footswitch can be connected to the Tap/Exp. jack.In addition: the Twin-Lazers tap-tempo oscillator automatically resets to the beginning of the cycle upon the second tap-tempo press so you can time it and fit it into your song perfectly.\nAll this, with the new \"K-1\" graphic on a tough-as-nails matte black powder-coate","images":["https://cdn.shopify.com/s/files/1/0174/5126/products/TwinLazers-Kali-Front.jpg?v=1667247027","https://cdn.shopify.com/s/files/1/0174/5126/products/TwinLazers-Kali-Right.jpg?v=1667247030","https://cdn.shopify.com/s/files/1/0174/5126/products/TwinLazers-Kali-Left.jpg?v=1667247030"],"price":269.95,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:48.908Z"},"share_url":"https://firestarter.network/l/lst_hEZojswI","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
