Louder Than Liftoff

Pulse Tape Delay Colour


  • Fully Assembled

The Pulse Colour from Louder Than Liftoff puts a perfectly tuned, vintage tape echo at your fingertips. With one click, Pulse makes it sound as though you've spent hours tweaking a tape echo and equalizer for the perfect atmosphere and tone. In fact, that's exactly what designer Brad McGowan has done. Pulse is an entire tape delay signal path, featuring delay, saturation, and filtering, tweaked to recreate the sound of Brad's beloved Otari echo deck.


  • Compatible with the Colour 500-Series Palette
  • Customize your Pulse with solderless jumpers:
    • Delay time
    • Feedback (repeats)
    • Saturation on/off
    • Wet/dry ratio
    • Insert (variable wet/dry) or send (wet only) mode
  • Combine with LTL's Pentode Colour for a true tube echo sound
  • Frequency response painstakingly tuned by ear to sit in any mix
  • Compatible with the Colour 500 Palette

Due to the complexity of the circuit, Pulse is not sold as a DIY kit. All LTL Colours are sold fully assembled, calibrated, and tested by ear.

I absolutely love the way that real analog tape echo and slapback can add depth and dimension to a vocal or guitar track. A subtle dose can integrate a dry source into the space of the mix like nothing else. I use this simple effect so much that I knew we had to capture the sound of my trusty Otari 1/4" 2-track echo deck and miniaturize all those motors and tape heads for the Colour format.

Real analog plugins.

Colour is a new format for analog audio gear designed for and by the DIY community. We took our favorite sounding analog circuits and put them on modules that are small, affordable, and swappable.

The Colour format consists of Colours and Palettes:

Colours are ultra-compact, pluggable analog circuit blocks that impart various types of analog color. Check out our ever-growing selection of Colours. Colours can be designed and released by anyone.
